App Store Reviews
Loved by players worldwide.
"The fretboard just 'clicked' for me as I dragged the notes around. This app made it really easy to understand how the notes relate to one another."
"Its amazing the number of things this app can do others can't — for free even. I'm an experienced guitar player and I haven't come across anything this useful. 10/10"
"Best app for finding new chord shapes I've ever seen. The idea of showing all chord degrees on the fretboard to allow finding of new shapes is genius."
"This is the best app out there for finding scales and chords in alternative tunings. You can custom set any tuning and then drag the chords up the fret to find anything."
"Thank you for making a tool for the music community that doesn't have any in-app purchases. The app has very good UX, keep up the good work!"
"This app does everything it needs to do with no fluff, ads, or in-app purchases."
