Apple on Monday touted the findings of a new study that says the app store was responsible for $ 519 billion in estimated total Billings and sales of both physical products and services and digital goods in 2019.

Apple may receive a 30 percent cut of digital items. That includes the biggest category, mobile games, as well as in-app purchases, some subscriptions.

The study is careful to say that the figure is not the same as total app store billings. Analysis group says it counts some items, like streaming video subscriptions, that may be purchased elsewhere.

In-App advertising, also largely dedicated to mobile gaming, makes up another $ 45 billion. Of everything else – from ride-hailing software to food delivery apps to mobile retail shops from Best Buy and target – making up the remaining $ 413 billion.

These figures are generally in line with what we know about the company’s fast-growing services business. But it is interesting to see a concrete breakdown of this granularity.

Apple wants developers and regulators to think of the app store as a sprawling economy that is’dynamic, competitive, and flourishing’.

The Department of justice and the Federal Trade Commission take a closer look at whether Amazon, Apple, Facebook, Google, and Microsoft have too much power and wield it in anti-competitive ways.

Apple has faced criticism over the years for its mandatory 30 percent cut. The European Union is now investigating Apple after its music streaming rival filed a formal antitrust complaint.

The added pressure appears to have led to some consumer-friendly new features, like Siri support for Spotify. Much of the conversation centers on whether Apple’s become a benevolent dictator or a mutual benefactor in a symbiotic ecosystem.

Travel apps are responsible for generating $ 57 billion in bookings and sales. Ride-Hailing apps and food delivery generate $ 40 billion and $ 31 billion.

The retail industry’s mobile models include the mobile apps of big chains like Walmart and target. The study calculates the amount of revenue generators.

Of the $ 519 billion app store ecosystem supported in 2019, the study found that sales from physical goods and services accounted for the largest share, at $ 413 billion. Retail apps include those that digitally represent brick-and-mortar stores such as target and Best Buy.

Travel apps, including Expedia and United, accounted for $ 57 billion. Uber and Lyft, comprised $ 40 billion in sales, and food delivery apps made up $ 31 billion.

The US accounts for less than half of the total $ 519 billion at just $ 138 billion. China contributes an estimated $ 246 billion.

The study concludes that estimated sales and Billings and total app store billings are the result of the study. The study also concludes that the study is based on the fact that the research was done.
