Best Friends led our list of apps this week; the app asks users to invite their friends before being able to see photos, statuses, birthdays and more in one interface. The Portuguese and French versions of this app also made the list, as did a Chinese friend app, 我的忠實粉絲.

Solitaire Blitz led the games on the list, which included a game in Arabic, مدينة الأهرامات.

The RockMelt browser made the list was the only off-site integration this week. Amazon Sweepstakes is a significant app on the list because brand promotions rarely make the charts. The sweepstakes is hosted on a tab on Amazon’s Facebook page, but it is not the default. The page drives traffic to the app through posts that reach users in News Feed.

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