Ratings and Reviews

Great app


In a nice layout it provides complete picture of the fretboard, in my case banjo. I have several books on scales, chords but this APP ties it all to fretboard. Well worth having - good reference and look up AP.

Developer Response

Thank you Bo-Kral for the kind words! I decided to write the APP for that exact reason. I had tons of charts and book but nothing connected them immediately. At that point in time I was working on chord melodies and finger style guitar, I wanted something I could quickly reference scales and chords as I worked out the movements.

No information, Banjo incorrect


Would it kill you to list the instruments and all of the tunings somewhere in the description?
Also, the banjo fretboard is incorrect. The high fifth string doesn’t begin at the nut.
The support email on their website bounces back undelivered.

Hi ZC111,
Sorry you were not happy with the APP. We will be addressing the banjo bottom string going to the nut in a future release.

The current engine we built did not take into account partial string lengths, but we felt adding the banjo option would add more value than not including the instrument.



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- it also includes a four-string bass mode making it extremely useful to the student of the "walking" base line. 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!
