  • Great app
    by Bo-Kral
    In a nice layout, it provides a complete picture of the fretboard, in my case, banjo. I have several books on scales, chords, but this APP ties it all to the fretboard. Well, worth having - useful reference and look up AP.
  • Surprisingly Awesome
    by Steve the Ripper
    As a Song Writer, musician, and aspiring producer, this is a fantastic app. It's great for practice giving me a reference for chords and scales on both the ukulele and guitar.
  • Finally!
    by BuffaloShrimp
    Chord illustrations in chord apps are typically limited to six-string guitar chord tones that one can capture with four fingers - six notes max. This app not only reveals chord tones over the entire fretboard but also includes a four-string bass mode, making it extremely useful to the "walking" base line student. Chord and scale selection is quick and easy (not the miserable rolling wheel). This is a wonderful app! If a note name/modal number toggle (All I see are black and red dots) and the notes on the nut were added to the mix, I'd give this app eight stars! Thanks for a great app!
  • Not for beginners but..

    When I got his app, I knew very little about scales and keys on a fretboard. At first, I couldn't see any rhyme or reason. I didn't even know what the numbers meant. But pretty much after I figured that out, it turned into a fantastic resource that is fast and easy to use.
