Friend Quizzes, Tab Apps, Skype, Calendar, Are You Interested? and More on This Week’s Top 20 Growing Facebook Apps by MAU

Page tab applications and friend quizzes dominated our list of the fastest growing apps by monthly active users this week. Elsewhere on the list was a dating app, Skype’s app and a pair of Phrases apps, still not available in the United States. The titles on our list gained the most MAU of any apps on the platform, growing from between 708,300 and 12 million MAU, based on AppData, our data tracking service covering traffic growth for apps on Facebook.

Note, as well, that all apps show a five-day reporting lag due to a bug last week. However, no data is missing and everything is back to normal now.
