Fretly Launch

Fretly is live!

More than twenty years in the making: what began in 2005 as a desktop experiment called Fretboard Knowledge, and from 2016-2026 was this website with static images, is now a complete, interactive fretboard for the advancing guitarist. Scales, chords, modes, voicings, charts, and a study book that ties it all together.

Read the story and take a look: fretly.app/release.php

The app has incredible features all ready, but it will be growing and improving on a daily basis. 

I'm also very much looking forward to publishing a series of books, so keep an eye out for that as well!
