Slide FunSpace is once again a leader on our weekly AppData list of fastest-growing applications by monthly active users. However, some of the growth is beginning to appear problematic for Slide. While gaining about 12 million new MAU since February 22nd, Slide appears to have actually lost daily active users.

The company is certainly doing better than it was before FunSpace, along with its games, began its precipitous growth in mid-February. But the proportion of monthly users who return to FunSpace on a daily basis has shrunk from a modest average of five percent to about three percent. Even Slide’s games have remarkably low DAU as a percentage of MAU, coming in not much higher than FunSpace. However, media-sharing apps like this tend to have low DAU numbers simply because users don’t typically have something to share through the app every day.

Also, on the list below, FunSpace is topped by Static FBML, but you can disregard the latter, despite its just passing Birthday Cards to become Facebook’s second-largest app; it’s a Facebook-owned app that’s just showing how many users interact with customized HTML in Pages. Here’s the list:

It has been a while since Graffiti has registered as a top gainer, but the art app has risen to a new level of quality in the interim. There’s now more professional-looking art on the app, and more users are attracted by periodic competitions. Graffiti also now redirects users to its own site to buy custom art prints from its users, in partnership with Zazzle, so it could be generating good income.

Birthday Album is a 2pad app that creates a calendar of friends’ birthdays and sends out reminders; simple, but obviously effective, as the Album managed to pick up almost all of its two million MAU over the past week.

Most of the remaining top ten are games, which we’ll talk about over at Inside Social Games. But take note of Dedica una cancion and Dedica una canzone. These two are the latest examples of successful apps that have been cloned in multiple European languages, in this case Spanish and Italian. The apps are for sharing and listening to music, although it’s not clear whether they actually have licenses for their music.
