Great idea, but..
It tends to lag on iphone 4, especially when retrying a level - which can be a big distraction and quite irritating at times. Also, the layout of the colours and the background can be pretty boring at times to look at, which will lead to limited plays. BUT, This could be a GREAT app. It could be directed at musicians (guitarists, hand drummers) as a way to "help improve your sense of rhythm" but the app needs some big improvements! (1. There should be a time signature option to turn on in the settings menu to give you a sense of how to count if you do happen to play an instrument!?) I will continue to use it though. Please look for ways to improve this! Thank You
