Although there are more Android phones than iPhones, Apple has held the lead over Google in attracting apps in recent years. Many developers prefer iOS because iPhone users tend to spend more and are typically more sought after by advertisers. However, the large number of Android devices is starting to turn the tide. “Each individual iPhone is still more lucrative than a single Android device for app makers, but the overall size of the Android market is starting to be large enough to overcome the per-device difference,” reports Re/code. “Two recent studies suggest the Android ecosystem has started to overtake the one surrounding the iPhone.”
