Can I give less than a star?

This is the biggest waste of money Ive ever spent on an app. It always crashes and when it does work its so choppy it gives me a headache. Not to mention the fact that the iOS7 version doesnt even have a keyboard and if you click the wrong button looking for it the tutorial video starts playing and the only way to even stop it is to hard close it and go back in? Dont waste your time
