Dress Up for Halloween on This Week’s List of Fastest-Growing Facebook Apps by MAU

Phrases is once again the leader of our weekly AppData list of fastest-growing Facebook apps by monthly active users. But the app is not having an easy time growing to 50 million MAU, which will put it in striking range of FarmVille.

During the recent scandal over the sharing of user IDs with third party advertisers on Facebook, Phrases was temporarily unavailable. Now it’s again displaying a simple message: “Phrases is unavailable.” This message doesn’t match previous app suspensions we’ve seen from Facebook. For now, we’re not sure whether Phrases is running afoul of Facebook policy enforcement, or is simply having technical problems.

Here’s the full list:

Disfrázate, in Spanish, translates to “dress up”. The app has shot up over the past week, probably because of Halloween. Here’s what it looks like:

Next up, SmileyCentral is doing quite well with a plug-in that displays smileys in place of emoticons on Facebook. That’s followed by The Autism Spectrum Quotient Test, which is a bit like the Myers Briggs tests that litter Facebook and the broader web in essentially being a free version of a professional psychological test.

RockYou! is on its way back up, led by Birthday Cards, which once had almost 50 million MAU. Moving down, the list gets into the games — My Kingdom, Ravenwood Fair and Crime City are all new titles from small developers, doing quite well.
