App Store

On January 12, Eddie Cue dropped a few significant digits on us:

The App Store alone saw over 850 million average weekly users globally. Developers earned over $550 billion on Apple platform since 2008.

Apple Pay eliminated well over $1 billion in fraud, while generating more than $100 billion in incremental merchant sales globally. Purchases made through Apple Pay significantly outpaced the overall growth in consumer spending levels during the peak holiday shopping period in November and December. Apple Pay is now available in 89 markets. with more than 11,000 banks and network partners — including more than 20 local payment networks. Tap to Pay on iPhone expanded to 34 additional markets — now covering most of Europe — and is live in a total of 50 markets, with more than 15 million merchants of all sizes across the world accepting contactless payments using just an iPhone

Apple TV eclipsed all prior viewership records in December 2025, with 36% increase in monthly engagement (total hours viewed). To date, Apple TV has amassed 672 award wins and 3,085 nominations (excluding 2026).

Apple Music reached all-time highs in both listenership and new subscribers.

Apple Fitness+ expanding to 28 additional countries and regions offering more than 8,000 workouts and meditations in 4K Ultra HD.

In 2025, Shazam generated over 1 billion recognitions per month.

Expanded Share Item Location feature in Find My to 27 additional airlines, bringing the total to 36. (This feature allows private and secure sharing of an AirTag’s or Find My network accessory’s location with an airline’s customer service, reducing “truly lost” or unrecoverable luggage by 90 percent)

Apple Podcasts expanded transcripts to over 125 million episodes in 13 languages.

Apple News solidified its position as the No. 1 news app in the U.S., Canada, and Australia, and No. 2 in the UK. News features over 3,000 publications and more than 600 titles with Apple News+. News+ expanded its offerings with the debut of Apple News+ Food, which includes 100,000 recipes from 60 publications in the U.S., the UK, Australia, and English-speaking Canada. Apple News now includes over 150 local newspapers and news feeds across 50 U.S. states, seven Canadian markets, and London.

Apple One Individual and Family plans are available in more than 100 markets world-wide, with Apple One Premier, which also includes Apple Fitness+, available in more than 20 markets.

Historic data is not available on most of these singular data points however they are available at least for the payments to developers. In fact, there are 26 such data points. They are shown in the graph below as the blue dots.

The green dots and curve fitting them is my estimation of the total billings for App Store. That is, the total spent by customers on the App Store. To date, that amount is over three quarters of a trillion dollars. ($733 billion to be precise.)

Note that the data can be represented by a third order polynomial. Furthermore, since the r-squared is 0.9999, the function is very predictive. As an exercise, using this analysis it can be determined that $1 trillion will be achieved by the first quarter of 2028.

The beauty of a polynomial growth rate is that the rate of payment, that is the amount paid on a monthly basis, is itself accelerating. The following graph shows the payment rate in $million/day for developers.

This growth suggests that quite soon we will be nearing a rate of $300 million/day or $100 billion per year developer payment rate.

This is, of course, only the tip of the iceberg. As Eddie Cue points out in the press release,

In 2024, the App Store ecosystem facilitated $1.3 trillion in developer billings and sales, with more than 90 percent of that commerce going directly to developers, with zero commission paid to Apple.

To understand the totality of transactions on Apple platforms we need to explore the entirety of the App economy. There is for another post. Stay tuned.

According to JP Morgan analyst Samik Chatterjee, citing Sensor Tower, Apple's App Store revenue for May 2025, increased by 4.9% month-over-month (which compares to an average sequential increase of 2.3%) and an acceleration of year-over-year revenue to 13.0% in May versus up 11.8% in April. On a year-over-year basis, the App Store downloads increased by 3.1% in May (versus +5.8% in April) according to Chatterjee.

This analysis is based on app download sampling and may be indicative of the activities of consumers on the App Store. Services revenue in the first calendar quarter was $26.6 billion, up 12% year-over-year and at an all-time revenue record. Services gross margin was 75.7%, up 70 basis points sequentially, also an all-time record.

The world however seems to be having a problem with Apple Services. After years of skepticism of its relevance, now that it has achieved a run level above $100 billion/yr., it's being criticized for being harmful to competition.

The comments that it's unfair to developers or that it deters innovation are uninformed to say the least. What is missing from that analysis is that the App Store is only a small fraction of the entire ecosystem around Apple's platforms and that the economic activity the platforms enable is immense.

Let's learn.

Over the last year Apple reported a bit more than $102 billion in revenues for Services at a very high margin. The reason it was such a high margin was partly due to the fact the Services does book all payments from customers through the App store as revenues. In other words it does not include payments to developers as either revenue or costs. Those payments pass through but they are certainly part of the economic activity on the store. It would be indeed unusual for a physical store not to report what it pays for what it sells as part of revenues. But this is the basis Apple chose (or was obligated to choose) as the way to report App Store revenues.

Thus considering the payments to developers, the economic activity directly related to the App Store amounts to $120 billion/yr which includes commissions of about $30 billion/yr (last 12 months) and payments to developers of about $90 billion/yr (implying about 25% blended average commission rate.)

So including payments to developers the Services business grosses $186 billion/yr. of which 102 billion is reported as revenue, with the 75% gross margin and $90 billion is paid to developers "off the books".

But that $102 billion in revenues is only about 30% App Store commissions. The rest includes many types of income: It includes:

• Advertising which consists of Apple's own advertising services and third-party licensing arrangements notably the distribution fees for Google search (accounting for most of Googles "TAC" or traffic acquisition costs.
• AppleCare, Apple's own extended warranty service.
• Cloud Services which provide content synchronization.
• Digital Content which not only includes the App Store but also stores for books, music, video, games and podcasts. Apple also offers digital content through subscription-based services, frequently bundled, including Apple Arcade, essentially a game subscription service; Apple Fitness, a personalized fitness service; Apple Music, which offers music streaming and on-demand radio stations; Apple News, a subscription news and magazine service; and Apple TV, which offers exclusive original content produced by Apple and live sports access licensed sometimes exclusively by Apple.
• Payment Services which offers Apple Card, a co-branded credit card, and Apple Pay, a cashless payment service.

The quarterly view is summarized in the graph above. So a fixation on the commission is only a view into 16% of Services as an economic foundation (the orange area in the graph above).

But that's still only a sliver of the whole picture.

A report written by Jessica Burley, Analysis Group and Professor Andrey Fradkin, Boston University Questrom School of Business has estimated that the global App Store ecosystem facilitated $1.3 trillion in developer billings and sales in 2024. As the report writers say: "For more than 90% of the billings and sales facilitated by the App Store ecosystem, developers did not pay any commission to Apple."

How is this not visible? The reason is that this economic activity is distributed over the millions of purchases Apple users make through its iOS Apps every day. This includes traditional App Store "Billings" including paid downloads and in-app purchases, including subscriptions, that use Apple’s in-app purchase system and “Sales” which includes money spent by customers purchasing goods and services in general using any iOS and iPad OS apps. Apps developed by Apple such as Apple Music, Safari or browser apps such as Chrome are excluded from this analysis.

The economic activity unleashed by the App Store now reaches well over $1.3 trillion/yr. As the authors further explain,

While the present analysis captures the major app monetization strategies available to developers, the full economic impact of the App Store ecosystem extends beyond the estimates provided in this report, as the current methodology does not capture all of the ways in which the App Store ecosystem facilitates sales, or all of the benefits created by apps. For example, the App Store supports “companion apps” that raise the value of a company’s goods and services, including smart home apps and health apps. In addition, many apps now use different monetization strategies. As such, this analysis does not account for all the ways in which the App Store ecosystem creates value.

Furthermore the report breaks down the categories as Digital Goods and Services, Physical Goods and Services, M-Commerce (General Retail, Travel, Food Delivery and Pickup, Grocery, Ride Hailing), Digital Payment and In-App Advertising.

In addition the report estimates these categories from 2019 as well as 2024 providing a growth perspective: Over the past five years, the App Store ecosystem has more than doubled in size, increasing from $514 billion in 2019 to nearly $1.3 trillion in 2024.

It also identifies regional dynamics between the US, China, Europe (with select countries) and Rest of World (with select Asian countries).

I've been keeping my own analysis of what I called the Apple Economy and it includes these transactions outside the App Store and Apple's own products and services. If I were to subtract Apple's own revenues from the total, for 2024 I was getting about 1.4 trillion (out of a total of over 1.8 trillion).

My point was always to estimate the economic impact of Apple beyond its own sales. This gave us perspective to assume that in 2025 the total would reach over $2 trillion. The graph below gives the perspective which also implies a doubling since 2020 to 2024.

The new report from Burley and Fradkin is a detailed, bottom-up analysis which quantifies what was perceived as the economic value of Apple being far more than what the financial data records.

Bill Gates once stated in reference to Zuckerberg's assertion that Meta was developing a "platform" that it's not a platform unless the economic value of everybody that uses it exceeds the value of the company that creates it.

Apple captures about $30 billion as sales but delivers over $1.3 trillion in sales, a multiple of 43! I would call that generous. In addition it doubles the market in 4 to 5 years. I'd call that market expanding not constraining. Finally, it's a market that Apple created out of nothing. I'd call that market creation not destruction.

If judged on the question of creation and satisfaction of the customer, i.e. the ultimate purpose of the firm, the App Store and Services in general has satisfied 1.4 billion people. That they are spending over $1.3 trillion and doubling in 4 years is nothing short of astonishing.

We'll discuss this topic and other topics related to Apple at ACTIVE: The Apple Investor Conference, which takes place on next Tuesday, June 10th, the day after the WWDC25 keynote.

Apple Investors are keen observers of metrics of financial performance. We have to track top line, bottom line and many lines in between. Updates to the data are delivered every quarter through official documents such as the 10K and statements made in conference calls. These data are then analyzed and opinions are formed on the viability, sustainability, and prospects for the company.

The community of investors changes rapidly, with shareholders able to enter and exit with a click of a button. All it takes is capital. Therefore many critics of shareholders as stakeholders point out how fleeting the commitment can be. Though there is skin in the game in the form of committed capital, there is no requirement for staying committed.

This is not the case for another set of stakeholders. In a previous post I pointed out how important employees are to the company and my belief that their commitment is probably management’s greatest concern.

But if one were to sum up the total population of a stakeholder group multiplied by its required level of commitment, there is a case to be made that the most vested community is that of Apple’s developers.

This group numbering in the millions makes an enormous contribution to the prosperity of the company and indeed of the other stakeholders. And they do so through tremendous personal risk. If you are a developer you know this, but perhaps other stakeholders do not. So let me elaborate.

An Apple developer must spend years becoming versed in the developer tools, purchase membership and equipment, navigate getting their software accepted and hope that someone, anyone buys the result. Afterwards, they need to maintain the code and update it frequently as the underlying software and hardware changes.

This adds up to enormous personal opportunity costs. Developing means not doing something else and developing for Apple means (typically) not developing for some other platform.

The benefits can be significant however. Apple publishes the amounts paid to developers. That is part of the graph shown below.

The dark blue area shown as “App Store Billings” includes about 70% paid to developers which I would estimate at about 100 billion in 2023. 

But these are direct payments based on App Store transactions. A great number of transactions and economic activity takes place outside the App Store. That is over $1.1 trillion in 2023. It should grow to over $1.3 trillion this year. 

And then there is AI. As Ben Bajarin and I discussed recently, the integration of AI is shifting the risk/reward equation for developers to include capital spending or monetization of computation itself. 

A lot is at stake. Not only in terms of upside but also downside. Developers need to understand the “state of the union” for Apple as a platform and ecosystem from a financial point of view. Conversely, investors need to understand the degree of dependence and commitment being made by the developers. 

There has been no forum for this to happen. Until now. 

At the first Apple Worldwide Investor Conference ( WWIC ), we will bring together individuals with a stake in Apple's future—investors, analysts, and developers—to foster a meaningful conversation about Apple's ecosystem, and a better understanding of Apple as a business.

The event will take place on September 19th, in-person in Boston with limited seating, and via remote livestream globally, where you can watch, ask questions, and discuss, live.

Tickets are available now. Asymco followers can get an additional discount using code asc24.

See you at WWIC—in person or online!

As I remember it, at least 10 years ago, I began to hear anecdotes from developers who built apps for both iOS and Android about their economics. The story is that they tended to have twice as many users using Android but that iPhone App Store revenues were roughly twice those of Google Play Store. From that I devised a rule of thumb that an iPhone user was about 4 times more valuable than an Android user. Half the users, paying 4 times as much means double the income.

Over the years I came across a lot more data about market development (the diffusion of innovations) and market creation (the innovation process) and applied it to transportation. Along the way I also became more aware that figures of consumption and spending are not normally distributed. That it turns out that the governing function of much of human behavior is log-normal. That is, it is skewed rather than balanced or symmetric around an average. Classic examples are income distribution and the distribution of travel distances.

Consider the following diagrams: Trip Distances vs. Trip Speeds for New York Citi Bike travelers (n=42.7 million.)

The different lines represent different time periods spanning the months of the year.

The top graph shows that most trips are short, and the average distance is not the most common distance. The bottom graph shows that the average speed is the most common speed. The top graph is very accurately modeled with the log-normal function. The bottom graph is the classic bell curve of the normal or Gaussian function.

Income is log-normally distributed and so it has to be with services revenues. There must be a definite skew where there is a disproportionate spend by those who have more income. Thus segmenting or, to put it less kindly, discriminating customers properly is super important. Customer quality is just as important, perhaps more so, than quantity.

So let's revisit the question of user quality for online services.

Unlike 10 years ago, there is a lot more data. The EU, for instance requires a report of the number of users on each platform.

The figures I want to focus on are those of Apple App Store and Google Play Store: 123 million and 284.6 million respectively. These are strikingly similar to the ratio of 2x between iOS and Android from my old anecdotes. However, if we look at global data, Apple claims 650 million active App Store users while Google claims 2.5 billion active users. That makes the global ratio closer to 4x Android. However, if we look at the US, the ratio is 167 million iPhone users vs. 144 million Android. In the US, iOS is a majority.

This is explained by income. The wealthier the user base the more iOS seems to be in use.

Now let's look at revenues for the platform stores.

On the right side is the history of retail revenues by year from 2016 to 2022 and split between Apple App Store and Google Play Store. Mirrored on the left is the number of users, also split by store but also by region, but only for 2022. [App Store revenues are my own analysis (with validation against other sources) and include billings not just Apple's own cut. Play Store revenues are from Business of Apps.]

The ratio between revenues has kept remarkably steady, with 2016 revenues at a Apple:Google ratio of 29:15 (1.93) and 2022 at a ratio of 81:42 (1.93).

The global user numbers are, as mentioned, 3.8 to 1.

[Aside: One sanity check on the data is that the 650 million App Store users is about half of my estimate of iPhones in use (1.2 billion). That might be alarming. Why are only 54% of iPhones in use paired with App Store use? However, if we take the sum of both App Store and Play store users (3.15 billion) and compare it with the total number of global smartphone users (6.92 billion), we discover that 45.5% of all smartphone users use some store. Adding Chinese Android stores we can see that the ratio of 54% for iOS is somewhat consistent.]

Thus we can compare the app revenue per user of the two platforms by dividing global revenue number by the global user numbers. The results are shown below:

I scaled the spending to a per-month basis.

So the picture becomes clearer. The iPhone customer is 7.4 times more valuable than the Android customer. This is more impressive than the 4x rule I had 10 years ago. The reasons are mainly that my anecdotes were from developers who sold products in the US or EU whereas expansion of smartphones to 7 billion global users has drawn in more lower spending customers.

But Apple's base has also grown to over 1 billion users (650 million store users). This highlights that Apple has effectively grown and discriminated customers effectively. It obtained not just 1 billion customers but the best 1 billion customers.

How to discriminate effectively is the holy grail of marketing. The naïve approach is to keep prices high. But that usually only results in a "luxury" branding and a small base that tends not to grow. The alternative "premium" approach is to offer functionality and multiple tiers and distribution options and financing and merchandising. There is no simple formula.

The bottom line is that Apple's approach is attracting 650 million $10/month app spenders. When we factor in additional subscription services, we get to the juggernaut that is Apple Services. This analysis has shown how difficult it is for anyone to come close to this quality of revenue.

As we look forward to Spatial Computing, the idea of increasing that spend from $10/month for a small glass rectangle in your palm to perhaps $100/month for an immersive 360-degree 3D experience does not sound too crazy.

But only if you can find those customers. I suspect Apple already knows who they are.

The App Store ecosystem crossed $1 Trillion in 2022.

To be precise, in a report published in May 2023 by the Analysis Group the ecosystem is estimated to have exceeded $1.1 trillion. This ecosystem is defined as the total transactional value of the sale or distribution of digital and physical goods and services through apps. It also includes in-app advertising. The analysts relied on a variety of data sources, including data from Apple, app analytics companies, market research firms, and individual companies.

Note that this includes Apple's own services as well as App Store developers. Unlike Apple's own reporting of payments to developers (and thus partially revealing its own App Store revenues) this data includes payments which are not captured by Apple directly. In the words of the authors, "More than 90% of this figure originated from transactions that did not happen through the App Store, meaning that these amounts accrued solely to developers and other third parties, and that Apple collected no commission on them."

This $1.1 trillion figure is almost double the value from 2019. Ecosystem estimates were first provided in 2019 at $519 billion, with $643 billion in 2020, $868 billion in 2021 and $1,123 billion in 2023. These correspond to growth rates of 24% in 2020, 35% in 2021 and 29% in 2022. The compound growth rate has been 29.4% since 2019.

It would be ambitious to expect this CAGR to continue after the Covid boom but at the same time, it's worth noting that this growth out-paces Apple's own services growth rate. Services (reported) revenues grew at 18%, 27% and 10%. The actual figures and growth rates are shown below.

This Analysis Group report is very much worth reading and adds an important new metric of resilience and scope and scale of the platform and ecosystem that Apple has created.

However it is also not the complete picture. I strive to see the larger picture of what I call the Apple Economy. This includes the ecosystem as well as the direct revenues Apple obtains from products and services. [Of these revenues, roughly 60% is then passed on to Apple's suppliers, with less than 20% retained as earnings].

Therefore, the combination of ecosystem and revenues is shown in the following diagram.

Note that the "Economy" size was over $1.4 trillion when the ecosystem alone was $1.1 trillion. Note also that I'm also suggesting that it's likely to be $1.6 Trillion this year. This diagram shows the story since 2019 but also makes a forecast to 2025.

I'm expecting the ecosystem to grow more modestly at 18% in 2023 (down from 29%) and 16% in 2024 and 15% in 2025. Apple's own product and services sales are also subject to estimation error.

Nevertheless, it's not unreasonable to believe the forecast above where the Apple Economy expands to over $2 Trillion by 2025. This is an acceleration from previous forecasts.

It's difficult to write about the implications of this. Any value in the trillions is hard to put in context. Certainly, Apple's market capitalization is in the trillions. For fun, we can calculate that Apple is trading at a multiple of 1.74 of its economy.

But rather than trying to assess valuation directly, Apple's Economy is more like a GDP figure: I think it's helps to understand the overall scale and resilience. You might even ask what would happen if it were to cease to exist. The number of people who are employed in a $2 trillion economy is in the millions; perhaps 10s of millions of people.

In 2023, global GDP is expected to reach $105 trillion. It's nice to think that Apple could soon be about 2% of the world.

App Store spending was $1.8 billion in the last week of 2020, up from $1.42 billion the previous year —an increase of 27% vs. an increase of 16% from the previous year.

On 1/1/2021 App Store spending reached $540 vs. $386 million for 1/1/2020. This was an increase of 40%. The previous year's increase was 20%.

Developers selling through the App Store have now earned more than $200 billion since the App Store launched in 2008.

The previous year's figure was $155 billion, making the 2020 total $45 billion, a 30% increase from $34.5 billion average of the previous two years. Assuming a proportional increase, overall ecosystem transactions rose to $675 billion in 2020. This places Apple's valuation at a 3.2 multiple of its yearly ecosystem value and each customer is valued at approximately $1400.

The history of App Store revenue and the growth rates involved is shown below.

NB: A substantial amount of App Store revenue is derived through subscriptions which now total about 600 million.

A simple summary is that the App economy accelerated its growth in 2020. This implies an economic value reaching $1 trillion/yr. within two years. It would behoove the investor to evaluate the value of Apple as a multiple of its ecosystem as well as a multiple of its customer base.

As I have repeated over time, the strength and resilience of Apple is in its customer base. Strength in terms of willingness to spend for quality and value and resilience in terms of sustained satisfaction. As that base grows to well over 1 billion people and as this billion are exposed to an increasing spectrum of value options (products, services and ecosystem) the company becomes indispensable.

This is quite the opposite of the perceptions widely held even a few months ago.

In March 2016 Ben Bajarin and I put on an event called SUBSCRIBE where we asked, among other things,

• How will the online services business models evolve?
• How will hardware affect software and services and vice versa?
• How will  users, usage, and capital connect?

Now is a good time to look back on that event.

For the keynote I prepared a model which predicted the mobile ecosystems for iOS, Android and Chinese Android over the next 5 years (to 2020). The methodology involved taking a measurement of the revenues of the top internet service companies, building up the categories these companies occupied, estimating how much of those revenues are through mobile distribution and then splitting the result among the three platforms of iOS and the two Androids.

Adding to that the "native" app and content revenues for each platform would yield the Ecosystem total value. Applying a growth rate would offer some visibility into the future.

The following images are screen captures of the Perspective presentation.

Of course there are several potential errors in this methodology. The categories were not all inclusive. I used Social, Media, Search, Maps, email, Messaging, e-commerce, Travel, Enterprise, Storage, Transportation, Travel and Other as the top level categories. There are many products and services who would end up in Other. Moreover, these categories were anchored by the top companies in each category and the share of the top names was not always clear. Finally, the growth rates for these categories were based on historic trends which could change either way.

The online services ecosystem (all platforms) was thus estimated to be $450 billion in 2015, growing to $820 billion by 2019 and $914 billion by 2020.

The mobile split would vary by segment but would be roughly 75% by 2020 (25% would not be mobile). The final assumption was based on the split among the existing mobile platforms. I put a multiple of roughly 50% for iOS and 35% for Google Android and the rest for China Android.

Multiplying all these assumptions gave me a figure of $275 billion for the iOS portion of the global online services market in 2019. (Incidentally, Android was estimated at $207 billion and China Android $110 billion.) Note that this does not mean this was an expectation of Apple's revenues or that this was the opportunity of Apple obtaining any percentage of this revenue. It was simply the value of what would transact through iOS, a platform which would act as a commerce enabler. This was to be the size of the iOS "ecosystem" or co-dependency between Apple and the companies delivering through its platform.

Ecosystems are a powerful idea. As I recall, this term applied to mobile was coined by a Palm executive in the late 1990s when he referred to the value of all the apps built for the Palm Pilot. The biological term refers to the system of multiple species living in close proximity. It implies an equilibrium as each species benefits from the others and the environment. There might be predators and prey but biodiversity is the successful construct.

The idea of an ecosystem for a platform was also the core strength of Microsoft's Windows which created the network effects around it and it has been the goal of every platform since. The nature of computing and networking implies that these systems grow faster and are more resilient than the more traditional value networks of other businesses or industries.

Now this ecosystem was something we wished to highlight in 2016 as a core strength for Apple. It was not considered as such at the time and I thought putting a figure of $275 billion in 4 years' time was a way to highlight the potential. Time since has proven us right.

This week Apple highlighted the result of another research team who attempted to measure the iOS ecosystem. Their conclusion was that billings and sales facilitated by the Apple App Store Ecosystem in 2019 was $519 billion. More than twice the amount I had so optimistically forecast four years earlier.

The authors also emphasize that this is a conservative estimate and should serve as a baseline.

I feel partly vindicated about that figure as my attempt at a figure was intended to highlight the scope of the ecosystem and it is better to have underestimated it than overestimated it. The authors' methodology was also similar in being bottom-up summation of components by categories of services but the information available today is enhanced by the new data Apple made available on subs and Services revenues and install base.

Note that in the graph below the salient data points of subscribers (red triangles) had not begun until 2017 causing the acceleration in Services revenue (yellow line). Note also the additional square points representing install base.

This figure of more than half a trillion dollars of value transacted through iOS should give some pause. It it a very powerful figure that can be combined with the other data from Apple:

• More than 1.5 billion active devices
• More than 1 billion iPhone users
• More than 500 million paid subscriptions
• More than $1/day iPhone hardware revenues for Apple

The half-trillion per year on services implies between $335 and $520 in spending per user (likely closer to $500) per year. This would be in addition to the approximately $365/yr in hardware spending per user (which Apple books as hardware revenue). In the case of the iPhone there is yet more: the cellular network service which may average $350 per year.

To simplify, the "average Apple user" spends $1/day for each device, $1/day for the network and $1.4/day on items bought through the device. Adding a margin of error, that's between $3.4 and $4 per day each user spends. Oh, and there are about a billion such users.

The total spending enabled by iOS thus is close to $1.4 trillion/yr.

That's a significant amount. It's bigger than many industries. There are only about 12 countries with higher GDP (Spain is about the same.)

How does Apple benefit from this?

Apple captures 30% of billings through its App Store. My estimate for these billings were $67.9 billion in 2019 which means App Store billings were 13% of the 2019 ecosystem. Apple's 30% cut of Billings amounts to 3.8% for the whole ecosystem. It's hardly an oppressive number.

If Apple only captures 3.8% what use is this to Apple?

The last decade has seen Apple emerge as the world's largest company in terms of market capitalization, and not doing so with a wild multiple of revenue or earnings, quite the opposite. It did this by creating the world's greatest customer base. Not in absolute scale. Android and Facebook have larger customer bases with multiple billions of users.

No, Apple's one billion users are simply the best billion users. They are the most likely to stick with Apple and they are the most likely to buy more from Apple and—this is crucial—they are the most likely to buy everything else. Those other companies whose sales come from Apple customers have been taking note. They know that Apple customers are desirable customers and choose to target Apple customers, as much as they can. Associating your company with Apple makes a lot of economic sense.

I will admit however that my argument that Apple created a customer base is contrived. The fact is that Apple creates products and services and those products are the root of its power to attract the right customers. By choosing to create the best products it coincidentally chooses to create the best customers. The power flows from product not from pricing or positioning. This is a lesson lost for many.

Developers and regulators might feel Apple's massive power is perhaps too much. In the last decade, the narration around Apple has shifted from Apple being perpetually "doomed" to it being too dominant. Although I'm sure there are some who will try to conflate the two declaring that dominance will inevitably result in doom, most critics of Apple went from laughing (at it) to crying (about its practices).

The argument that Apple should change its practices developed to price as it does, distribute as it does or design as it does because it was too successful or is "unfair" is getting the causality wrong. Dominance won't be altered by a few points of percentage change (on a tiny fraction of ecosystem transactions). Fairness won't be altered when there are thousands of business models and many remain to be invented. Case in point is pornography which is not permitted on the App Store but which exists in abundance thorough other access methods.

The argument is that Apple should be more generous. That it should decrease the "cut" it takes for distribution. Or that it should not enforce revenue split for the customers it exposes to others.

But this is problematic on many levels. The playing field for all developers needs to be level. The customer must be respected and access to that customer should be constrained or certainly metered. Abuses must be policed and that requires leverage.

These practices are inter-dependent and the effect multiplicative, not additive. Apple has a monopoly on iOS and on MacOS and WatchOS and iPadOS. It does this to control the experience, security and safety of the user. It's that control which created the customer in the first place. It should naturally control access to its hard-earned customers.

It does not monetize the distribution of content or apps unless the developer/creator directly charges for the product or service. Distribution is not cost free and to offer it for free is a subsidy which would create additional market and innovation disincentives. The loyalty of Apple users is evidenced by the 600 million paid subscriptions (end of year estimate) that are booked through the App Store. Developers benefit directly as a result.

One could argue that the abundance of services which don't distribute through the App Store is evidence that the system works as intended. Apple's App store front is its property and it reflects its core values.

Being on the shelf in the App Store means you operate on the terms of the shelf owner. If the rules are not agreeable then the half trillion dollars of ecosystem activity is testament to the availability of alternatives.

The iPhone is the most successful product of all time.

Over 1.6 billion have been sold. Including the iOS products it spun off, the total is over 2.2 billion. Of those 2.2 billion sold, 1.5 billion are still in use.

There are about 1 billion iPhone users.

Economically speaking, iPhone sales have reached one trillion dollars. ((The milestone of $1 trillion iPhone revenues was reached in the fourth quarter 2018 during which time the stock price of Apple fell by 40%.))

Since the iPhone launched, Apple's sales have totaled $1.918 trillion. Of those trillions about one half a trillion was accumulated in the form of  income.

Of that half trillion in income, $360 billion was paid out to shareholders ((As a result, the number of outstanding shares has decreased by 29%)). and $131 billion was paid in taxes.

This sounds like a good business, but no business is good if it is static. What makes a business great is dynamism. The idea is to constantly maneuver for a new or enhanced way of doing business as technologies enable entrepreneurs to fundamentally change how value is captured or allocated.

The iPhone story isn't static, the "pivots" or change in direction are several:

• The App Store, a platform for collaborative innovation where millions of developers are offered the chance to improve the product.
• Accessories, a licensing model for third-party hardware that works with the iPhone
• Distribution through multiple channels
• Integration with other Apple Products
• The marketing of older products alongside new ones at reduced prices
• An expanded product portfolio with a broader range of prices
• Trade-in and financing options

Each of these initiatives contributed to the iPhone growth story but the biggest change in business model was the addition of services. Apple Services grew out of the iTunes business that pre-dates the iPhone and was established to provide content for the iPod.

In 2006, the year before the iPhone launched, Apple customers spent $3.3 billion on iTunes, Software and Services. By 2018 the spending rate was $80.5 billion/yr. It's very possible that this year's spending rate will reach $100 billion/yr. This new division is simply called Services today and consists mainly of third-party apps and third-party content sales as well as licensing.

Recently Apple launched a set of new services that it will offer itself. This includes television, films, financial services and news. Apple already has a music service of its own and file storage (iCloud) both of which are offered as subscriptions.

Apps are also allowed to offer paid subscriptions, and that total has reached 390 million, growing at 30 million a quarter with an expected total of 500 million by 2020. That amounts to one subscription for every other iPhone in use.

Some would argue that even with a $43 billion revenue rate, ($80 billion billing  rate) ((The difference is in the way Apple accounts for App Store revenues: declaring only the 30% portion of sales that it keeps as revenues, and not including the 70% that is paid out to developers. The "billing rate" is what consumers spend, the "revenue rate" is what Apple reports.)) Apple's business is still a hardware business and that comes with low margins, potential for disruption, non-recurring revenues and cyclicality.

This is not the case. Apples's business has high margins (64% gross margin for services, 34% for products), has been resilient over 12 years while attracting hundreds of imitators at lower price points, and has loyalty and satisfaction which results in more than 90% re-purchase rates. Cyclicality is driven by seasonality and product lifespans, not competition.

This common misconception of Apple is why it continues to be valued at a deep discount to not only peer companies who are services oriented (Google, Facebook, Microsoft and Amazon) but also at a discount to the overall market (the S&P 500).

Apple, since its inception, has always been oriented around its customers, not its products. The questions asked by management are "what can the company do to deliver experiences and satisfaction" rather than "what products can the company build".

Every company is bound by its capabilities but the best companies re-shape these bounds because they are defined by priorities.

A priorities-driven company habitually re-designs its processes and its resources. A resources- or process-driven company re-designs its priorities as its capabilities change.

Moving as it does between computers, devices, software, services, retail, logistics and manufacturing means that it's not classifiable as an "x" company where "x" is an industry sector. Rather, the company should be classified by the set of problems it seeks to solve (e.g. communications, community, productivity, creativity, wellbeing).

This disconnect between what people think Apple sells and what Apple builds is as perplexing as the cognitive disconnect between what companies sell and what customers buy.

Companies sell objects or activities that they can make or engage in but customers buy solutions to problems. It's easy to be fooled that these are interchangeable. ((They are only correlated. Purchase decisions are not *caused* by a product's existence. The real cause is a combination of need and supply and time and circumstance of purchase.))

Conversely Apple offers solutions to problems that are viewed, classified, weighed and measured as objects or activities by external observers. Again, it's easy to be fooled that these are the same.

This analysis is, of course, applicable to any company. Here I'm using Apple as a lens. This is because it's just so much easier to tell this story with the narratives and anti-narratives that are so widely disseminated.

In June of this year Apple reported that it had paid a total of $100 billion to developers. That is the 18th such figure given in the 10 year history of App Store, making the progress of payments and hence revenue and spending easily trackable.

The other regularly reported figure is the business segment revenue where App sales are currently allocated. Now called "Services" this omnibus segment includes many other sources of revenues such as:

• Digital Content (Books, Music downloads, Video downloads--including TV shows and movies and movie rentals.)
• AppleCare, Apple's extended warranty service.
• Apple Pay, transaction fees
• Apple Pro Apps, including Final Cut, Logic Pro, Motion, Aperture
• Licensing including "Made for iPhone/iPad"
• One-time settlements of various lawsuits.
• Other Services revenues which include
• Apple iCloud-related services
• Music Match
• Music subscriptions
• Other third party subscriptions (commissions)
• Third party licenses

This combined Services segment is significant with $35 billion revenues in the last 12 months. This is quite a jump from 2016 when Services had crossed $25 billion. At the end of 2016 Apple said it expected Services revenue to double by 2020. With a growth rate since then of 25% the company is on track to reach its target one year early. ((To calibrate this consider that Facebook revenues for the last 12 months were $48 billion and it now has a market capitalization of $468 billion or 41% that of Apple whereas Services consists of about 14% of Apple's total revenues.))

Consumer spending on Apple services includes more than what it books as revenue since only the (typically) 30% of App Revenues is considered Apple's revenue. Including the payments to developers, Services generated over $65.5 billion/yr in billings. This will reach $100 billion/yr in 2 years. The difference between reported revenues and consumer spending is shown in the following graphs.

I described the visibility into App Store revenues (which is the orange area in the graphs above) but the other sub-segments of Services are much more difficult to ascertain. Of special interest is Other Services which includes very high margin services. As part of that there is a peculiar source of revenues: Google.

It's known that Google pays Apple for the default placement of Google search within Safari on iOS and Mac OS. That payment is registered by Google as a "Traffic Acquisition Cost" or TAC. TAC is essentially payment for distribution where what is granted by the distributor is access to queries (traffic.) This way Apple acts as distributor for Google. So, for that matter, does Firefox which also receives TAC payments.

What is peculiar is that the amount of TAC paid by Google to Apple is becoming staggering.

A few years ago Google was paying over 20% of its revenues as TAC. Recently that ratio rose to 23%. Bernstein analyst Toni Sacconaghi estimated that Google paid Apple $1 billion in 2014 as TAC and that payments to Apple were about $3 billion in 2017. Now Goldman Sachs analyst Rod Hall estimates Google could pay Apple $9 billion in 2018, and $12 billion in 2019.

This is starting to look interesting but is it believable?

My own estimate of Apple's Other Services (which includes TAC revenues) is a run rate of $15 billion for calendar 2018. This makes $9 billion (60%) from Google quite challenging but not impossible. The remaining $6 billion needs to account for Apple's own cloud and subscription service revenues.

Does this make sense given Google's spending? TAC payments to distribution partners in Q2 were $3 billion. The $9 billion/yr assumption implies a $2.25B/quarter payment to Apple. That would be 75% of Google's distribution costs. That also sounds reasonable given the high utilization of iOS relative to any other platform.

An increase to $12 billion for next year is also quite a claim but it certainly is possible. I don't have a basis for making this estimate but the assumption of growth leads me to conclude that the payments are tied to actual traffic generated.

In other words the two companies have an agreement that Apple is paid in proportion to the actual query volume generated. This would extend the relationship from one of granting access for a number of users or devices to revenue sharing based on usage or consumption.

Effectively Apple would have "equity" in Google search sharing in the growth as well as decline in search volume.

The idea that Apple receives $1B/month of pure profit from Google may come as a shock. It would amount to 20% of Apple's net income and be an even bigger transfer of value out of Google. The shock comes from considering the previously antagonistic relationship between the companies.

The remarkable story here is how Apple has come to be such a good partner. Both Microsoft and Google now distribute a significant portion of their products through Apple. Apple is also a partner for enterprises such as Salesforce, IBM, and Cisco. In many ways Apple is the quintessential platform company: providing a collaborative environment for competitors as much as for agnostic third parties.

 

The following is a transcript of the comments from Tim Cook (CEO) and Luca Maestri (CFO) at Apple's Q1 2018 Earnings Conference Call February 1, 2018. I color coded my interpretation of the comments into four categories:

• Grey: Background and promotional commentary
• Red: Strategy and signals of what management considers important and may include data beyond the regularly reported numbers.
• Green: Financial data
• Black: Commentary.
• Blue: My commentary, in brackets.

For a quick read of Apple's strategy, read the Red text. These comments are not repeated in financial reports. Highly recommended.

For a quick read of Apple's financial performance, read the green text (which are replicated in financial reports). Read this if you don't want to wade through the financial reports.

For marketing or product material, read the grey text.This is sometimes unique but also repeats product launch information.

Tim Cook:  Thanks, Nancy and thanks everyone on the call, and welcome to everyone today. Before we dive into the quarter, I'd like to take a moment to talk about a significant milestone we recently crossed.

Apple's active installed base reached 1.3 billion devices in January and is at an all-time high for all of our major products. 1.3 billion devices represents an astonishing 30% growth in just two years. It speaks to the strength and reliability of our products and our ecosystem, as well as the loyalty, satisfaction and engagement of our customers. It's also fueling tremendous growth in our services business, which I’ll talk about a little later in the call. [This is probably Apple's most important number. For at least the next 20 years this is the key performance metric and it can be used to derive company's valuation. A summary of the history of active devices vs. units sold is shown in the graph below:]

Turning to the December quarter. We're thrilled to report Apple's biggest quarter ever, which set new all-time records in both revenue and earnings. We generated revenue of $88.3 billion, which is above the high-end of our guidance range, and it is up almost $10 billion or 13% over the previous all-time record we set a year ago.

It's also our fifth consecutive quarter of accelerating revenue growth with double digit growth in each of our geographic segments around the world. What makes us even more remarkable is that the quarter we're reporting today was 13-weeks long, while the year ago quarter was 14-weeks. When we look at the average revenue per week in the December quarter this year compared to last year, our growth was a stunning 21%. [The 13-week vs. 14-week year-on-year comparison is repeated several times. The summary differences are shown in the table below:] 

Our growth was broad-based and a key driver was iPhone, which generated its highest revenue ever. iPhone X was the best-selling smartphone in the world in the December quarter according to Canalys, and it has been our top selling phone every week since it launched. iPhone 8 and iPhone 8 Plus rounded out the top three iPhones in the quarter. In fact, revenue for our newly launched iPhones was the highest of any lineup in our history, driving total Apple revenue above our guidance range. [The iPhone X is a huge hit. It drove the average selling price $100 higher y/y. This is not only unprecedented for Apple but for the entire Industry. The average smartphone sells for less than $300 while iPhones sold for $800. The gap is widening. The following graph shows the product mix and the average resulting price.] 

I want to take a moment to recognize the tremendous amount of work that went into creating iPhone 10. Our teams carried out an extremely complex launch from both an engineering and operations perspective, executing an outstanding product ramp that required years of research and development; one that introduced innovative features like an edge-to-edge Super Retina Display and the TrueDepth Camera, which enables face ID. Our customers love these new features and the new gestures like simply swiping up from the bottom, which make using iPhone even more intuitive and enjoyable.

Our team has put the technology of tomorrow in our customers’ hands today, set a standard for the next decade of smartphones and we are very proud of their achievements.

It was another very strong quarter for services with revenue of $8.5 billion, up 18% over last year, and we’re on pace to achieve our goal of doubling our 2016 services revenue by 2020. The number of paid subscriptions across our services offerings passed 240 million by the end of the December quarter, that’s an increase of 30 million in the last 90 days alone, which is the largest quarterly growth ever. [Services has been growing relentlessly for over a decade. This steadiness of growth makes is a juggernaut. Apple is increasingly speaking about subscriptions as the key metric and 240 million is reaching record territory. The rise of Services is shown below (both revenues and consumer spending.)]

We had an all-time record quarter for the App Store with our best holiday season ever. We’re seeing great excitement around augmented reality with customers now enjoying over 2,000 ARKit enabled app, spanning every category in the App Store. In December, when Pokémon GO released its new augmented reality features built with ARKit, it jumped the top of the App Store charts. Last week, on a stop in Toronto, I met developers who are hard at work on creative applications using ARKit from art appreciation to ecommerce, and I was very impressed with what I saw.

Just for months after ARKit launched to the public, we’ve already released ARKit 1.5 in beta to developers around the world, and the response has been tremendous. Augmented reality is going to revolutionize many of the experiences we have with mobile devices. And with ARKit, we’re giving developers the most advanced tools on the market to create apps for the most advanced operating system running on the most advanced hardware. This is something only Apple can do.

In addition to the App Store, several other services had their biggest quarter ever, including Apple Music, iCloud and Apple Pay, all of which saw growth in both active users and revenue.

Apple Pay has reached an important milestone in the U.S. As a result of 50% year-over-year growth in merchant adoption, it’s now accepted at more than half of all American retail locations, which includes more than two-thirds of the country’s top 100 retailers. Now available in 20 markets, global Apple Pay purchase volume more than tripled year-over-year and we’re delighted to be expanding to Brazil in the coming months. [There are no absolute data points on Apple Pay but we do have some scattered growth data. The US data is cited here but in my experience it's more popular in select countries like UK where users are using it habitually]

Today, you can use Apple Pay to take the subway in Guangzhou, China, see a concert at London’s Wembley Stadium or buy a souvenir in Yosemite National Park. In the U.S., we launched Apple Pay Cash in December, and it’s off to a terrific start. Millions of people are already using it to send and receive money with friends and family quickly, easily and securely; to split a bill, pay someone back, or send last minute gift right from the messages app.

It was our best quarter ever for the Apple Watch with over 50% growth in revenue and units for the fourth quarter in a row and strong double-digit growth in every geographic segment. Sales of Apple Watch Series 3 models were also more than twice the volume of Series 2 a year ago. Apple Watch is the most popular, smart watch in the world and gained market share during the quarter based on the latest estimates from IDC. [Apple Watch is growing consistently. The following graph shows my estimates of volume (total 42 million to date) and revenues (total $15 billion) based on all available data and commentary from management.]

It was the third consecutive quarter of growth for iPad revenue, thanks to the strength of both iPad and iPad Pro. Based on the latest data from IDC, we gained share in nearly every market we track with strong outperformance in emerging markets.

Worldwide, almost half of our iPad sales were the first-time tablet buyers are those switching to Apple, and that’s true in some of our most developed markets, including Japan and France. In China, new and switching users made up over 70% of all iPad sales.

For Mac, we launched the all new, iMac Pro in mid-December. It’s an entirely new product line designed for our Pro users who love the all-in-one design of iMac and require workstation class performance. It's the fastest, most powerful Mac ever, delivering incredible computational power, for simulation and real time 3D rendering, immersive VR and complex photography audio and video projects. Worldwide, 60% of our Mac sales were the first time buyers and switchers and in China, that number was almost 90%.

We're looking forward to getting HomePod in customers’ hands beginning next week. HomePod is an innovative wireless speaker, which delivers stunning audio quality wherever its placed in the home, thanks to the advanced Apple engineered hardware and software.

Together with Apple Music, HomePod gives you instant access to one of the world's largest music catalogs. And with the intelligence of Siri, it’s a powerful assistant you control through natural voice interaction. We're very happy with the initial response from reviewers who've experienced HomePod ahead of its launch, and we think our customers are going to love this new product.

We believe one of the key issues of the 21st century is education. And because of that, we've strengthened our commitment and investment into initiatives like everyone can code. To find the innovators of the future, we need to nurture the students of today. Our App Development with Swift curriculum, which is available free on iBooks, has been downloaded more than 1.2 million times worldwide with almost half of those coming from here in the United States. It’s also being taught in dozens of community colleges across the country, putting practical skills in the hands of today’s jobs seekers.

I was in London two weeks ago as we announced that the program was expanding to more than 70 colleges and universities in Europe. Millions of students around the world will have the opportunity to add Swift to their coding vocabulary and gain skills that are essential for today’s economy.

This is an exciting time at Apple and with the best lineup of products and services we've ever had and a set of initiatives that show how business can be a force for good in the world. We could not be more excited about our future.

Now, for more details on the December quarter results, I'd like to turn over the call to Luca.

Luca Maestri: Thank you, Tim. Good afternoon, everyone. Our business and financial performance in the December quarter were exceptional, as we set new all-time records for revenue, operating income, net income and earnings per share.

Starting with revenue, we’re reporting an all-time record, $88.3 billion, up nearly $10 billion or 13% over the prior record set last year. It is our fifth consecutive quarter of accelerating revenue growth. As you know, the December quarter a year ago spanned 14-weeks compared to 13-weeks this year, which is important to consider as we have set the underlying performance of our business this year. When we look at average revenue per week, our growth rate was even higher at 21% with growth across all product categories for the third consecutive quarter.

Our results were terrific all around the world with double digit revenue growth in all our geographic segments, an all-time quarterly record in the vast majority of markets we track, including the U.S., Western Europe, Japan, Canada, Australia and Korea, as well as Mainland China, Latin America, The Middle East, Central and Eastern Europe, and India.

In Greater China, we were very happy to generate double digit revenue growth for the second quarter in a row and in emerging markets outside of Greater China, we saw 25% year-over-year growth.

Gross margin was 38.4% at the high end of our guidance range. Operating margin was 29.8% of revenue. Our net income was $20.1 billion an all-time record, and up $2.2 billion over the last year. Diluted earnings per share were $3.89 also an all-time record and cash flow from operations was very strong at $28.3 billion.

During the quarter, we sold 77.3 million iPhones, the highest number ever for a 13-week quarter. Average weekly iPhone sales were up 6% compared to December quarter last year with growth in every region of the world despite the staggered launch of iPhone 10. We established all-time iPhone revenue record in nearly every market we track with double-digit growth in all of our geographic segments. iPhone ASP increased to $796 from $695 a year ago, driven primarily by the launch of iPhone 10 and the success of iPhone 8 and 8 Plus.

We exited the December quarter towards the lower end of our target range of five to seven weeks of iPhone channel inventory with less than 1 million more iPhones in the channel compared to the December quarter a year ago, in line with our growth in average weekly unit sales. Customer interest and satisfaction with iPhone are very, very strong for both consumers and business users.

The latest data from 451 Research indicates U.S. customer satisfaction ratings of 96% or higher across iPhone models. In fact, combining iPhone 8, iPhone 8 Plus and iPhone 10, consumers reported an amazing 99% satisfaction rating. And among business customers planning to purchase smartphones in the next quarter, 77% planned to purchase iPhone. Our customers are also incredibly loyal with Kantar's latest U.S. research, reflecting a 96% iPhone loyalty rate, the highest ever measured. [Customer satisfaction is the second most important figure after active user base. Combining these two figures yields the recurring revenue value of the company. Remember what Deming said: the most important measurements for a company's value are the multipliers of a satisfied customer and a dissatisfied customer--these numbers never appear on any financial report but they are applied to all the numbers on every report].

Turning to services. We had a terrific quarter with revenue of $8.5 billion, up 18% year-over-year and up 27% in terms of average revenue per week; that is an acceleration to the 24% services growth run rate that we experienced in the September quarter.

The App Store set a new all-time revenue record. The Store’s all-new design is off to a fantastic start with quarterly store visitors, transacting accounts and paying accounts, reaching new all-time highs. During the week beginning December 24th, a record number of customers made purchases or downloaded Apps from the App Store, spending over $890 million in that seven-day period, followed by $300 million in purchases on New Year’s day alone.

And according to App Annie’s latest report, the App Store continues to be the preferred destination for customer purchases by a very wide margin, generating nearly twice the revenue of Google Play. Across all our services offerings, paid subscriptions reached $240 million with growth of 58% over last year and they were a major contributor to the overall strong growth in services revenue. [Apple has half the user base of Google Android. This is based on Google's May 2017 report of 2 billion active devices vs. the 1.3 billion that we just got from Apple. And yet these users collectively spend twice as much on apps. This ratio of "half the users, twice the spending" has been cropping up in individual developer anecdotes and can also be seen in other metrics of engagement and consumption. This should not be surprising as it conforms to the Pareto distribution of economic value.]

As Tim mentioned, it was our best quarter ever for Apple Watch. And when we add to this us from Beats and AirPods, our total revenue from wearables was up almost 70% year-over-year. In fact, wearables were the second largest contributor to revenue growth after iPhone, which is impressive for a business that started only three years ago. In total, our other products category set a new all-time record with quarterly revenue exceeding $5 billion for the first time. [Wearables now includes more than watches but watches are likely still the dominant product.]

Next, I’d like to talk about the Mac. We sold 5.1 million Macs during the December quarter, which translates to a 2% year-over-year increase in average sales per week. Mac performance was particularly strong in emerging markets with unit sales up 13% year-over-year and with all-time records in Latin America, in India, Turkey and Central and Eastern Europe. On a worldwide basis, the active install base of Macs was up double-digits year-over-year to a new record.

It was also another growth quarter for iPad. We sold 13.2 million units with average iPad sales per week up 8% over last year’s December quarter. iPad sales grew strong double-digits in many emerging markets, including Latin America, the Middle East, Central and Eastern Europe and India, as well as developed markets, including Japan, Australia and Korea. The active install base of iPad has grown every quarter since its launch in 2010, and it reached a new all-time high in December, thanks to extremely high customer loyalty and large numbers of first-time iPad users. [iPad is clearly recovering from a long decline. ASPs are rising as it's being positioned as a PC alternative. Its low end functions are being absorbed by large screen iPhones.]

NPD indicates that iPad had 46% share of the U.S. tablet market in the December quarter, up from 36% share a year ago. And the most recent surveys from 451 Research found that among customers planning to purchase tablets within 90 days, 72% of consumers and 68% of business users planned to purchase iPads. Customer satisfaction is also very high with businesses reporting a 99% satisfaction rating for iPad.

We are seeing great traction in enterprise as businesses across industries and around the world standardize on iOS. For example, Intesa Sanpaolo, one of Europe’s leading banks, has chosen iOS as the mobile standard for its entire 70,000 employee base in Italy; choosing iOS for its security, user interface, accessibility and reliability, Intesa Sanpaolo will deploy native apps to improve employee productivity in customer support, human resources, and marketing across the company.

And LensCrafters, one of the largest optical retail brands in North America, will be using over 7,000 iPad Pros to enable digital eye exams and digital optical measurements in a personalized and interactive experience. We’re also rolling out a new initiative, called Apple AtWork to help businesses implement employee choice programs more easily and offer Apple products company-wide.

Resources from both Apple and our channel partners will enable enterprise IT and procurement teams to buy or lease Apple products more efficiently, streamline the setup of iPhone, iPad, and Mac, and deliver a seamless onboarding experience for employees. We launched the program with CDW in the U.S. last week, and we would be expanding to more channels and regions later this year.

The December quarter was extremely busy for our retail and online stores, which welcomed 538 million visitors. Traffic was particularly strong during the four-weeks following the launch of iPhone 10, up 46% over last year. And across the quarter, our stores conducted over 200,000 today at Apple sessions, covering topics including photography, music, gaming, and app development, and art and design. Just last weekend, we opened our first store in Seoul, Korea and we’re looking forward to opening our first store in Austria in a few weeks. These newest openings will mark the expansion of our retail store presence to 21 countries.

Let me now turn to our cash position. We ended the quarter with $285.1 billion in cash plus marketable securities, a sequential increase of $16.2 billion. $269 billion of this cash, or 94% of the total, was outside the United States. We issued $7 billion in debt during the quarter, bringing us to $110 billion in term-debt and $12 billion in commercial paper outstanding, for a total net cash position of $163 billion at the end of the quarter. We also returned $14.5 billion to investors during the quarter. We paid $3.3 billion in dividends and equivalents, and spent $5.1 billion on repurchases of 30.2 million Apple shares through open market transactions.

We launched a new $5 billion ASR program, resulting in initial delivery and retirement of 23.6 million shares and we retired 3.8 million shares upon the completion of our 12th ASR during the quarter. We’ve now completed over $248 billion of our $300 billion capital return program, including $176 billion in share repurchases against our announced $210 billion buyback program with $34 billion remaining under our current authorization. [An updated look at Apple's cash is shown below]

Turning to taxes. Due to the recently enacted legislation in the U.S., we estimate making a corporate income tax payment of approximately $38 billion to the U.S. government on our cumulative past foreign earnings. This amount is very similar to what we had been accruing on those earnings in our financial results through fiscal year 2017, including the $38 billion payment. We will have paid over $110 billion of corporate income tax on our total domestic and foreign earnings during the last 10 years for a cash tax rate of about 26%. [Apple has paid more tax than any company in history, and is about the make the largest single payment to the US Treasury.]

Our tax rate of 25.8% for the December quarter was close to our guidance of 25.5% as the lower U.S. statutory rate from the new legislation was effective offset by the remeasurement of deferred tax balances.

As we move ahead into the March quarter, I'd like to review our outlook, which includes the types of forward looking information that Nancy referred to at the beginning of the call; we expect revenue to be between $60 billion and $62 billion; we expect gross margin to be between 38% and 38.5%; we expect OpEx to be between $7.6 billion and $7.7 billion; we expect OI&E to be about $300 million; and we expect the tax rate to be about 15%.

Tax reform will allow us to pursue a more optimal capital structure for our company. Our current net cash position is $163 billion. And given the increased financial and operational flexibility from the access to our foreign cash, we are targeting to become approximately net cash neutral overtime. We will provide an update to our specific capital allocation plans when we report results for our second fiscal quarter, consistent with the timing of updates that we have provided in the past.

Finally, today our Board of Directors has declared a cash dividend of $0.63 per share of common stock, payable on February 15, 2018, to shareholders of record as of February 12, 2018.

In its latest update on the App Store Apple reported that iOS developers earned $26.5 billion in 2017. A year ago the figure was $20 billion. The growth rate is then about 33%. The cumulative payments to developers can be calculated as $86.5 billion. This amount was generated in a span of less than 10 years, with the first billion paid by June 2010.

The following graph shows the history of cumulative payments and the corresponding payment rate (in $/yr.)

Note that this represents the payment to developers, not the spending by the customer. Apple keeps about 30% of the revenue.  The total spending on the App Store is then about 43% higher. ((During the last year some types of app subscriptions have been priced by Apple at 15% of gross so I adjusted the payment rate to 72% for 2017)). The equivalent figures for spending on the App Store are shown below.

A few observations:

• Developer payment rate is now above $25 billion/yr. I've been notified via Twitter that this is higher than the revenue of McDonald's Corporation in 2016.
• During this year iOS users will be spending about $100 million per day for Apps. This was Google's AdWords revenue rate in 2012.
• The spending on App Store has been rising steadily, adding about $5 billion/yr since mid 2011.
• Apps are the biggest component of Apple services and helped that segment gross over $57 billion in 2017, passing Fortune 100 level (net of developer payments).

I've made comparisons before with the app business being bigger than the film industry (and much bigger than the music industry.) This was considering Android revenues and iOS combined as "app revenues".

As of this year the App Store alone will overtake Global Box Office revenues.

Of course this is only an observation of the scale of App Store rather than a judgement of the benefit obtained from either medium or the substitutability of one for the other. ((The substitutability of apps for movies is not to be discounted either. The analysis should be based on understanding the jobs the media are hired to do.)) The reason scale should be noted is that the App Store, and Apple services overall, is becoming one of the largest enterprises in the world. Even more importantly, it should be noted for its rate of growth.

Even when considering this, one should keep in mind that the figures of revenue and payments to developers are only a small fraction of the overall app economy. Apps sold to end users are a subset of all apps on the App Store. There are not only free apps but also many apps which are front-ends to complex services which are monetized in various indirect ways.

Facebook, Twitter, Linkedin, Tencent, YouTube, Pandora, Netflix, Google, Baidu, Instagram, Amazon, eBay, JD.com, Alibaba, Expedia, Tripadvisor, Salesforce, Uber, AirBnB and hundreds of others are all "free" apps enabling hundreds of billions of dollars of interaction none of which are captured in the App Store revenue data. The vast majority of activity for the top commerce, communications and media properties are now coming through mobile devices.

By weight of users and their propensity to engage, iOS enables about 50% to 60% of mobile economic activity.

Based on assumptions of revenue rates for mobile services and iOS share of engagement, my estimate of the economic activity on iOS for 2017 is about $180 billion. Including hardware sales, the iOS economy cleared about $380 billion in revenues 2017.

Additional assumptions around growth rates suggest that iOS economy will achieve the half trillion revenue rate in 2019. Valuing this, especially as a part of Apple's intrinsic value, is a challenge but it's probably worth doing. There are implications in the robustness or sustainability of the underlying business.
