Great idea of an app, it would be good with some attention maybe, I hoped there would be an update that made it great. And if it could keep the tempo... Update: I really like the idea of this app, if only it worked properly, it needs some work and in 2 years I've been knowing about it it hasn't improved anything, it lacks basic functionalities like tempo and measure changes, repeat signs, etc. It looks like the work of a single, not musician and not very dedicated to it developer...
