Facebook Gift Cards entered our list of emerging applications by monthly active users this week at No. 14 with 41 percent gain.

We define emerging applications as those that ended with between 100,000 and 1 million MAU in the past week. This week’s top apps grew from between 60,000 and 170,000 MAU, based on AppData, our data tracking service covering traffic growth for apps on Facebook.

Facebook Gift Cards is an app where users can buy and redeem Facebook Credits that can be used toward purchases in games and other apps that use Facebook Payments. The social network recently added a link to the Facebook Gift Cards app in its App Center. Users may also be visiting more often as they begin shopping for the holidays.
