Thank you, I'm happy that the app works for you!

Positive Reinforcement!

Learning the guitar fretboard is challenging to say the least, and this tool is great for your tool box. Long drive, long flight, long commute? Great time to study your fretboard. This app makes it fun and easy!

Interface is easy on the eyes

The color coding of the notes make it wayyyy easier to remember the scales compared to most apps that are out there.
