Connect any MIDI controller and calibrate it in seconds — press your lowest key, then your highest, and the on-screen keys line up with the real ones under your fingers.
From a 25-key mini to an 88-weighted stage piano — calibration fits the game to your gear.
Press physical keys to answer. It feels like practising, not tapping glass.
Every round is quick and repeatable — listen, answer, move on. Do enough of them and recognizing notes by ear turns from guesswork into instinct.
Tap play and a single note — or a full chord — rings out on a real sampled piano. Replay it as many times as you need.
Press the key you think you heard. Name the chord, or play every note of it back. Instant right-or-wrong feedback, no guessing games about the score.
Track your best streak and accuracy as your ear sharpens. Widen the range from one octave to the full 88 keys when you're ready.
Start with single notes. When you're ready, switch to chords and choose how hard you want to work.
Hear a chord and name its quality, or press every note you hear back on the keyboard.
Three chord sets that scale with you, from beginner triads to diminished, augmented, and seventh chords.
A sustain toggle lets notes ring or cut short — practice the way your instrument actually behaves.
Press anything and listen — unlimited, never gated, no scores. A quiet corner to explore sounds between rounds.
The same game on iPhone, iPad, Mac, Android, and Windows — tuned to feel native on each, with every new feature shipping to all of them.
Free to start — 20 rounds on the house. For unlimited practice, it's just a one-time purchase.
One App Store purchase covers iPhone, iPad & Mac. Android and Windows are sold separately.
