Ratings & Reviews

  • This app has not received enough ratings or reviews to display an overview.

The biggest update yet — a whole new Scales tab. • See any scale on the guitar fretboard or piano keyboard, color-coded by degree. Guitarists get the five CAGED shapes, full-neck patterns, and a Licks Library of ready-made riffs, now including Metal and Bluegrass. • Guitar chord charts now flip vertical or horizontal — whichever you read faster. • Progressions follow along — watch the current chord and what's coming next as your track plays. • Refreshed in-app help, cleaner controls, and a bunch of fixes. *Fixed in 2.2.1: guitar chords in the Progressions tab now play at the correct pitch — they were sounding a major third sharp. Thanks to the player who reported it! Thanks for playing! Ideas or requests? We'd love to hear them.
