Fretmap is a free web app helping you master your guitar scales, arpeggios or chords and shred with the best of 'em.
The app provides an interactive guitar fretboard allowing you to pick your root note, your pattern, and whether you’re a righty or a lefty.
Also, it's a Progressive Web App meaning you can save it to your device and use it like a regular app (even without an internet connection).
Fretmap is built with React, Next.js, TypeScript and Tone.js. Fretmap gets all its data from the Fretmap music service, hosted on Firebase.
Fretmap is built and maintained by Ghosthorses.co.uk
