Features
- Scale & Chord Finder: Tap the notes you're holding down straight onto the neck. Modes Guitar names the chord in real time — major, minor, diminished, augmented, extended, suspended and more — and ranks every scale that fits by note coverage. Filter by scale family to narrow the list, then jump straight to that scale's chords.
- Scales on the Fretboard: Pick a root and a scale and watch every scale tone light up across the neck. Switch to CAGED positions or three-notes-per-string runs, drag a box up and down the neck to change position, and narrow the notes to triad, seventh, pentatonic or the full scale to see the shape behind the shape.
- Chord Shapes: Every degree of the scale gets real, playable grips, complete with open- and muted-string markers, barre indicators and a fret-number gutter when the shape sits up the neck. Step through positions along the neck, choose an inversion, or force any scale tone into the bass for slash chords.
- 20 Tunings, Plus Your Own: Standard, Drop D, Drop C, E♭ Standard, DADGAD, Open G, Open D, seven-string, baritone, four- and five-string bass, ukulele, banjo (five-string, tenor and plectrum) and mandolin. Shapes, grips and note names are recalculated for the tuning you choose, and retuning keeps your fingering so you can hear what the same shape becomes. Or build your own: pick 3 to 8 strings and tune each one by ear, starting from any preset.
- Practice Metronome: A full metronome comes along for the ride: time signatures, subdivisions, swing, per-beat accents, four click voices, adjustable volume and haptics, plus quick tempos and saved presets for the passages you're drilling.
- Widgets, Control Center & Live Activities: Put the metronome on your Home Screen or Lock Screen and start or stop it without opening the app. Add a Control Center toggle, keep an eye on the tempo from a Live Activity while you play, and get a fresh Scale of the Day and Chord of the Day to work on.
