This app does has strengths and distinguishes itself in positive ways, but it does need changes. For now, what would probably turn many people off is that it closes the app if you click the "X" next to "premium" when you open the app, instead of hitting "+". Change at least that, and you'll probably get people to spend at least more than 10 seconds before ditching the app. The way it is now *looks* like you can't use it at all if you don't choose to pay immediately.
