Google Play has a reputation of not making much money for developers who offer their games there. However, not all developers agree that Google Play is not a moneymaker. In fact, developers like TinyCo, Spry Fox and Robot Invader are reporting that the Google Play revenue is on par with money they make from iOS versions of the game.
Some major studies have been published recently that claim Google Play earns about 1/8 of the daily revenue that the iTunes App Store generates. The money earned by some developers is very much at odds with the claim of poor monetization. For instance, Spry Fox CEO David Edery recently tweeted that one of his games, Triple Town, racked up $.67 via Google Play for every one dollar earned on the App Store.
That means the Android version of its game earns 67% of what the iPhone version earns, which is much closer than those recent studies would have us believe. Another developer has very similar reporting for Google Play. TinyCo says that it earned $.65 via Google Play for every one dollar earned on the Apple App Store. The key to earnings via Google Play appears to be carrier billing. Other developers report better conversions via Google Play than on the App Store. These reports really make you think about the validity of some studies.
