TripAdvisor had a 23 percent gain this week in part due to a Facebook ad campaign to re-engage users.

Social reader Terra and video app Chill continue to grow organically through Open Graph actions being shared to users’ feeds.

Instagram had a 5 percent increase, likely from users downloading an updated version of the app that was released last week. HootSuite, which got an update a few days ago, saw 150 percent gain.

Facebook canvas game Yu-Gi-Oh! BAM, released in June, had 311 percent pickup in the past week.

A number of custom landing tab applications are also on the rise.

All data in this post comes from our traffic tracking service, AppData. Stay tuned for our look at the top weekly gainers by daily active users on Wednesday, and the top emerging apps on Friday.
