Love this app!

Ive definitely seen differences. I try to do it every night. This is the first time Ive ever even paid for an app. The one thing I would like, is instead of explaining the game, show a quick video example or allow a practice round. Would love that. Having more than one paid user on the same device is klunky. That needs to be fixed.
