Hi, let me just say that I love this app and I'm currently recording an album with it. I'm using it on my iPad 3 more than my iPhone though and I'd love to see more use of the larger screen, like the bar at the bottom could contain loads more stuff (specifically the metronome) so you don't have to hunt around for it. The interface would look great on the new retina if it was reskinned to take advantage. I'm not joking when I say this but if you contact me I'll happily do the art work on a high-res interface for free cos I love this app so much
