Apptapper web app (not a game)

[macdev]

Hi, this is a project I did for the owners of Apptapper, an iphone review site. They asked me to make an app for their site, and I'm looking to test it. There's already several changes that are on the making for this initial release, and I'm looking for suggestions on how this app could be done better. Here's the itunes page:

AppTapper for iPhone and iPod touch on the iTunes App Store

The app is free. Runs best on the iphone 4.
