Beautiful Redesign... Finally!


Finally someone redesigns some music apps for iOS 8. It's beautiful and has finally been updated to support larger iPhones. I love that there is a choose button and that the up and down arrows have been moved to bottom making it easier for one-handed use. I also love having a play button.

Great but....


Great application, but it's annoying how the application will close after a small amount of time. I find that when I'm studying my scales the app closes on me. Its me it's quite frustrating. Other than that the application is great and very useful.

Out Of Pitch


I like everything about this app except the fact that it’s a half step ABOVE standard 440 pitch and in settings ; there is no allowance for PITCH ADJUSTMENT ..... fixing this flaw would get you that fifth star from me
