Everything on one stand

Each tool earns its tile. Open the app, and the things you use most are already waiting.

Sing & Play

Chords and lyrics on your own stand. Pick your part — vocals, guitar, keys, bass, drums — and the chart opens ready to play, even with no signal backstage.

Metronome

A dial you can grab mid-song. Accents, subdivisions, tap tempo, and time signatures from waltz to whatever your drummer is going through.

Tuner

Chromatic, guitar, bass, and ukulele. Auto-detects the string you're on and shows exactly how far you are from true — down to the cent.

Chord lookup showing C major with three guitar fingerings

Chords

Look a symbol up, or name what you're playing. Every quality from plain triads to altered jazz colours, with real fingerings for your instrument.

Scale table showing C major spelled out and drawn on a fretboard

Scales

Every scale worth knowing — spelled, drawn on the fretboard, and played out loud. Basics to modes, jazz, world, and the properly exotic.

Make it yours

Level up each instrument, earn badges, and spend your Neko Coins in the Dressing Room — outfits, pets, stage effects, and a wall of amps for an avatar that gigs as hard as you do.
