Aside from the popup on first launch, there's no help screen, so I can't figure out how to arrange things properly. I tried visiting the gallery and it's not sized for an iPhone screen, so I have to scroll around to see the entire picture. I think in the process of developing this, you may have used it too much to see any usability problems. I'd suggest finding someone who's never used your app before and physically watch them use it for the first time. Most importantly: don't say a word to help them! You want to see what it's like for first-time users of your application. After they're done, get their feedback on whether they'd use it again or not. This should only take a couple minutes. If you do this with 2-3 people, you'll realize a few things you could do to make the first use more compelling.
