Apple Inc. (AAPL), Google Inc (GOOG): America We Know What You’re Downloading

Apple Inc.Don’t worry, The Motley Fool hasn’t been tracking your downloads — but the research firm App Annie has. Their latest report shines a light on consumers’ mobile app preferences and how those apps translate into revenue for companies like Apple Inc. (NASDAQ:AAPL).

Playing is big business
The report found that 40% of all app downloads in Q1 of 2013 for both Apple Inc. (NASDAQ:AAPL)’s App Store and the Google Inc (NASDAQ:GOOG) Play store were games. More importantly, games made up 70% of all App Store revenue and 80% of all Google Play store revenue in Q1 2013.

Apple Inc. (NASDAQ:AAPL)‘s game app revenue increased by 25% from the previous quarter and Google Inc (NASDAQ:GOOG)‘s skyrocketed by 90%. Part of the increase may have come from China’s surge from 10th-largest app revenue contributor a year ago to fourth place now.

So games are going gangbusters in both app stores, but what about the actual app revenue each company is making?

Back in February, Apple CEO Tim Cook said in a conference call that the company has paid $8 billion to developers since the app store opened. As The Wall Street Journal reported a few days ago, based on Apple’s 30% take from all app sales, this would translate into about $3.4 billion for the company over the past five years.

Google Inc (NASDAQ:GOOG)’s app revenue is much harder to nail down and it hasn’t said how much it has paid out to developers. What we do know is that Apple made 2.6 times more in app revenue than Google Inc (NASDAQ:GOOG) in the last quarter, according to App Annie. Keeping this in mind, as well as the fact that Google Play launched after the App Store, it’s likely Google is bringing in less than Apple Inc. (NASDAQ:AAPL)’s app revenue estimate.

Not the only game in town
Although Android and iOS are the dominant players in the app market, we can’t forget about Microsoft Corporation (NASDAQ:MSFT)‘s Windows Phone Store or the Research In Motion Ltd (NASDAQ:BBRY) World app store.
