As a high school student (well, graduate tomorrow!) who is interested in designing mobile applications, I would really be interested in reading about your experience building this app. Not only the design and code, but the release and launch, if you don't mind.

I just bought the app and it's great! Keep up the good work!

EDIT: Just one little quirk I've noticed. The comment test is really small (I'm visually impaired and already hold the phone a few inches from my face). While I can read it, could you give us an option to increase it at some point in the future?
