It’s been over a month since I launched my Foursquare Badges Facebook application, and the excitement has since died down. Both for me and the press. But surprisingly, people are still finding out about my app and using it (I have over 1500 users now). Facebook has their own data and visualizations about users, but I am also tracking this information on my side. For example I can tell that my growth rate over the last month has been like this:

There are a couple of peaks. On the 6th, my Facebook app was approved and included in the Facebook directory (meaning that a Facebook user can search and find it). Then on the 12th, Foursquare released their application directory and since then I’ve been averaging a good 40-50 new users a day!

In contrast, I also created a Facebook application for Free iTunes Downloads. I didn’t publicize it because it doesn’t really serve much of an advantage to the end user. However, users have been finding the app on their own and adding it, although nowhere near as well as my Foursquare one. I’m still waiting to break 100 users on my FiD app, but the user growth graph is more wild.
