21 questions topped our list, growing by more than 4.5 million DAU. This app allows users to answer tongue-in-cheek questions about their friends and publish the results to their feed. The app also alerts friends that they were the subject of the quiz. The other five quiz apps on our list mirror this structure in various ways: Between You and MeTruth Game, Truths About You, My Friend Secrets and Get Revealed.

Games on the list were led by Zynga Bingo, which was the only game to gain more than 1 million DAU. Horoscope apps in a variety of languages were also popular. These apps usually post daily to users’ feeds after being installed.

Socialcam, the video watching app, continued to see strong growth, as did similar app Shufflr. There was also the Microsoft Facebook integration and an Indian mobile app, Facebook by Fonetwish that promises to allow users to use Facebook — even if they have no Internet on their phones.
