Okay, but there are better apps – Scales & Modes Review

It's good for what it does, but overall it is inferior to the Nota app, which has many more scales, and has chords and stuff. I have both of these apps and I feel I would have been just as good without this one. But, if all you are looking for is scales and modes, by all means grab this.
