Jazz chords, scan & practice
Free · In-App Purchases · Designed for iPad. Not verified for macOS.
You know the chord name. Your hand doesn’t. Snap the chart or play a recording — chords, numerals, scales and shapes, all at once, with a band ready to play.
The chart says Dm7(b5). You know the name. Your hand still doesn't know where to go.
That's the moment this app was built for. Photograph the chart or play it a recording, and you get the chords, what each one does in the key, the scales that fit, and 3–5 shapes people actually play. Hit play, the band comes in, and you drill it beat by beat.
Chart scanning, song recognition and chart import: 3 free uses of each after you sign in; Pro (auto-renewing subscription; the annual plan includes a 7-day free trial) has no limit. The full list is at the end.
■ One photo, the whole chart
AI reads the chords and the melody, with roman numerals, harmonic function (T/SD/D) and the matching chord-scale. Switch between staff, numbered notation, guitar tab with chord grids, chord chart and analysis. Anything it gets wrong, you can fix.
■ Play a recording, get the song
Pick a recording and get the melody, chords, bass and drums — see, hear and edit them on a MIDI piano roll or a falling-notes keyboard, and export MIDI.
■ Proper sheet music, one tap to export
Full screen is a real page: four bars to a line, with title, composer, key and tempo. Export staff, numbered, guitar and chord charts as PDF or images to print or share.
■ Shapes curated, not dumped
From common to advanced jazz chords, typically 3–5 curated, playable voicings each, across positions and inversions. Tap a chord grid on the guitar tab to try the next one.
■ Practise alone, sound like a band
Accompaniment styles × bass lines (walking bass included) × drum patterns, at any tempo. Record yourself and play it back right away.
■ The rest of the kit
Precise tuner (guitar mode with alternate tunings, chromatic mode for any instrument or voice), metronome from 2/4 to 12/8 with tap tempo, circle of fifths, full chord library.
■ Nine original etudes, with commentary
Major ii–V–I, minor iiø–V–i, jazz blues, AABA, turnaround, plus major pentatonic, minor pentatonic and blues-scale studies — not just what to play, but why it sounds good.
■ Pro (subscription)
Includes: unlimited chart scanning, song recognition and chart import (iReal Pro, MusicXML, MIDI), the full band (bass, keys, percussion) with every sound, transpose, practice recording, levels 2–3 of rhythm and ear training, all tuner tunings and chromatic mode, custom metronome time signatures. Everything else is free.
Monthly or annual, renewing automatically; the annual plan includes a 7-day free trial for eligible users. Prices are shown in the app. A subscription renews within the 24 hours before the current period ends and is charged to your Apple Account; cancel anytime in Settings › Apple Account › Subscriptions.

Recognition is AI-powered and can be wrong — always defer to the actual score.
