I've created this app as a theory reference for myself, while learning to play the guitar, I hope you find it useful too :) No ads.
What it does:
- shows scales and modes
- scale box pattern highlighting
- simple metronome
- scale harmonized triads
- supports custom tuning guitar and bass
- "left-hand" option.
- plays notes on touch
