60photos, if you recall, is an app that induces virality by using photos and asking users to rate them either “nice” or “pass.” Every “nice” rating is posted to the Wall of whoever’s photo it is; the app grew by 3.6 million MAU this week. MyCalendar, which allows users to create their own customized birthday calendars, grew by 1.8 MAU.

Quiz app 21 questions grew by 1.5 million MAU, and a similar app, Friend Buzz, grew by 1.2 million MAU. Both apps allow users to answer questions about their friends, posting answers to their Walls. Socialbox, a chat app download, grew by 472,900 MAU and Between You and Me is also a quiz app that publishes answers to questions to the Walls of a user’s friends with 344,600 MAU this week.

Page tab apps this week included Static HTML: iframe tabs with 2.4 million MAU, Static Iframe Tab with 541,900 MAU and Hosted iFrame with 433,500 MAU. Then there were mobile apps, Facebook for Every Phone with more than 2 million MAU and Samsung Mobile with 380,500 MAU. Finally, Yahoo’s app grew by 817,700 MAU and Bandsintown by 384,100 MAU.
