Thanks to strong performance in India and Brazil, Google Play had 10 percent more app downloads in Q2 2013 than Apple's App Store, according to App Annie. However, Apple's App Store still generated 2.3 times the revenue.

App Annie continued with the analysis:
Russia has climbed six spots in the iOS App Store download rankings since Q2 2012 and broke into the top 5 in Q2 2013. This growth put Russia in the unique position as the only other country besides the United States in the top five countries by downloads for both the iOS App Store and Google Play.
Brazil climbed two spots and joined India and Russia in the top countries by downloads for Google Play, further establishing Google Play’s leadership position in those emerging markets."
One reason for this effect may relate to the sheer volume of products being shipped and activated with the Android OS, and that's now percolated into secondary metrics, such as app downloads.
Another factor that comes into play is that Android users are less likely to pay for apps and gravitate towards lower cost, ad supported apps while iOS customers, being more affluent, seem to be willing to pay for productivity-oriented apps. This has been explained by Dr. Mary Ellen Gordon of Flurry Analytics in her recent blog: "The History of App Pricing, And Why Most Apps Are Free." Of course, a strong and financially healthy developer market is something Apple has always promoted.
One category that helped iOS: "...the substantial growth of Music and Social Networking apps helped drive iOS App Store revenue," according to App Annie.
The App Anne report has much more detail, including the breakdown of app downloads and revenue by platform and by country.
