Viddy, tabs, horoscopes, calendars, greetings, Zynga, more on this week’s top 15 emerging Facebook apps by MAU

There was an interesting mix of applications on our list of emerging apps by monthly active users this week. Aside from the usual mix of games, there was a phone video app, a few tabs, horoscopes and calendars, then greeting card apps and a quiz app.

The apps grew from between 110,000 and 390,000 MAU, based on AppData, our data tracking service covering traffic growth for apps on Facebook. We define emerging applications as those that ended with between 100,000 and 1 million MAU in the past week.
