My first android app

I just finished my first android app. What do you guys think?
It's not available on google play because google hasn't processed the 25$ developer fee payment yet. But you can get it on amazong appstore or via direct download.

I don't have github. What would you need it for? I really don't know what this board is about but it seemed like the most appropriate place to post it to.
