Josh Costine notes that the number of "daily active users" to Facebook from Android phones just surpassed the number from Apple iPhones for the first time. Another sign of Android's growing importance -- Facebook developed new features for its Android app first.
Facebook for Android‘s monthly user count of 85.4 million still lags behind the iPhone app’s 99.1 million MAU. However, this stat isn’t as important as DAU, or stickiness — the percentage of monthly active users that return daily. Android’s stickiness is 68.2%, compaed to iPhone’s 57.9%. This could indicate that Android devices appeal to a younger, more Facebook-engaged audience, or to more hardcore technology users in general. The iPhone’s role as a fashion and status symbol may be drawing less engaged users.
