FORTUNE — App Annie, the mobile analytics site with the friendliest name, is the first to report that four years after it was launched as Android Market, Google’s (GOOG) app store has overtaken Apple’s (AAPL).
Driven by Android’s rapidly growing market share, 10% more of the world’s population downloaded Google Play apps in the June quarter than App Store apps, according to Ask Annie results published Wednesday.
But in the same period, the App Store generated 2.3 times more revenue — probably because so many of those Android apps were free.
