Boring

If you think this is an app when you can harmonize your voice, its not. Its boring and it sounds like church music which to me is not good so deleted it and im never gonna get it back!

Highly creative, but needs an update for iOS 7

I love this app, but upgrading to IOS 7 makes the interface too big. I no longer see all the panels, and the notes no longer play or show reliably when the panels are touched. The wonderful relationships between the rows and columns of panels no longer exists.
The last update was for iOS 4 over 2 years ago. Will someone help keep this app alive, or will Chroma be the only app remaining that uses Shepard tones to help us understand music in such a creative way?
