Learn an instrument with an app that hears you honestly.

why kalimba? — Number tabs that map 1:1 to your tines.

20 instruments, one honest engine. Playsoloist apps listen while you play and tell you the truth — which notes rang clean, which drifted, and exactly what to drill next. No confetti for mistakes. Every note is heard and graded on your device.

The catalogue — a suite for 20 instruments

Every instrument, taught with the same honesty.

What the family stands for

The honest music teacher in your pocket.

Raw mic evidence, graded on your device

Always on-device

Your playing never leaves your device

Listening and grading run entirely on-device. Supported transcription features run there too. Our backend has no audio endpoints at all.

Nothing watching you

No account required to start, no ads, no trackers

Open an app and play. Optional account features are clearly labelled.

Never inflated

Honest grading, never inflated

“Heard 14 of 16 notes,” not a participation trophy — the feedback that actually makes you better.

Your own songs

Practice music you choose

Make tabs manually in Kalimba; supported Soloist apps can also capture a melody on-device. Each app page shows exactly what ships.
