Frettle is a free, open source app that shows every note, chord shape and scale on the neck of a guitar, bass, ukulele or mandolin. Pick a chord to see all the ways to play it up the neck, with the root and intervals marked and barres drawn in. Pick a scale to see it across the whole fretboard, split into hand-sized groups, along with the chords that fit it. Tap any note to hear it.

I've been learning ukulele and guitar, and I was struggling a bit to learn the fretboard, so I built a free and open-source web app that shows chords and scales for multiple string instruments and different tunings.
After trying a bunch of similar apps, I found they were either too complicated, didn't show chords and scales together on the same neck, or were full of ads and in-app purchases.
