For the first time, the Facebook for Android mobile app has eclipsed the daily active user count of Facebook for iPhone. The Android app launched in September 2009 more than a year after its iPhone sister and has been playing catch-up ever since. Both are developed internally by Facebook. This week the two were briefly tied, but the Android app is now pulling away with 58.3 million DAU compared to the iPhone app’s 57.4 million, according to the AppData tracking service.
