No piano?
No problem.

Tap a table, your pocket, or the air. It all counts.

Not sure which mode? Let One read the room

Intelligent detection

Let One read the room — keyboard, surface, posture, movement, headphones — and suggest the right mode.

Any flat surface becomes the keyboard.

Honest limit: Key resistance, so dynamics are estimated rather than measured.

Timed session

Five minutes on a bus counts as real practice.

Table mode · no piano needed

Prop the phone above a flat surface so it can see both hands, then tap the constellation on the table. Everything is processed on your device.

Your hands are busy. Speak instead — One answers aloud.

How every mode feeds one memory

One shared musical memory

Table, air, pocket, rhythm and keyboard all strengthen the same constellations. They're weighted differently because they measure different amounts of truth — a keyboard knows your dynamics, a thigh tap knows your pulse — but nothing you do is discarded.

Concept · no launch date

A keyboard that clips to your phone

A compact Bluetooth MIDI keyboard, magnetic, two octaves, thin enough for a coat pocket. We won't build it until enough people ask — and One will always work with any Bluetooth MIDI keyboard regardless.

Create an account so every surface feeds the same memory score.

Camera frames, motion and microphone data never leave your device — only the resulting scores are saved.
