Professional ranking app Identified comes in at the No. 1 spot on our list of top growing Facebook apps by monthly active users this week. The app’s 425 percent gain came from a one-day spike of 3.6 million daily active users. That’s dropped down to 90,000 users per day now, but the app still appears at the top of our MAU chart as a result.

Titles on our list gained the most MAU of any apps on the platform, growing from between 300,000 and 5.1 million MAU, based on our AppData tracking service.
