Not really 15 apps

This app is really one app with 15 options. The button to switch between the options is really small. Cant figure out where the free one is. There isnt one button to erase your picture to start over fresh. You have to shake your iPad which can be dangerous with young kids. I want a refund but cant even find how to contact the developers:(
