Useful App, some suggestions for updates – Scales & Modes Review

The explanations regarding music theory or easy to understand. I am a guitar player of 12 years that is currently learning the violin. Since there are no frets, playing along with the audio for scales is amazingly helpful. One major improvement that would help: add scales that have 2 and 3 full octaves so that we can utilize the entire range of the music bar and our instrument.
