65-percent of revenues for the top 200 Android apps come from in-app purchases, download store analysts Distimo have discovered, though the potential for making cash from Android software still pales in comparison to iOS. Meanwhile, Android is the place to go for free titles, holding a comfortable lead ahead of its rivals when it comes to freely-distributed software.
iPhone apps in the top 200 make almost four times the revenue - looking at both upfront payment and in-app purchases - of Android's top apps, while iPad apps make more than twice that of Android. Android holds the second spot for gaming options, too, with 46,045 titles in the US in comparison to the iPhone's 79,077 and iPad's 28,638.
Angry Birds was the top app of 2011 for downloads, Distimo found, followed by Facebook and Skype. Google's own Google Maps came in fifth, despite only being offered in the Android Market.
