Fretkit: Scales & Chords

About this app

Fretkit is the guitar and bass toolkit that's actually a pleasure to open. A beautiful, interactive fretboard sits at the center — explore scales and chords across standard and alternate tunings, tap notes to hear and see how they sit on the neck, and switch between guitar and bass. A fast, accurate chromatic tuner gets you in tune in a noisy room. And an animated circle of fifths turns music theory into something you actually want to play with — tap a key to see its scale light up on the fretboard and its diatonic chords fall into place. No account. No sign-in. No clutter. The essentials are free.
