Your wrist becomes the antenna. Tilt for pitch, raise and lower for volume — the legendary instrument you play without ever touching it, now on your Apple Watch.
Play it with a wave of your hand.
↔
Tilt for pitch. Sweep smoothly across the range, or lock to musical scales — major, minor, and pentatonic.
↕
Raise and lower for volume. From a whisper to full voice, controlled by the height of your hand.
◎
Digital Crown & readouts. Set your ceiling volume, watch the pitch in Hz and note names as you play.
⌚
One tap from your wrist. Add a complication to your watch face and start playing instantly.
✓
Private by design. No logins, no ads, no data collection — nothing ever leaves your wrist.
The theremin is played by moving your hands through the air near two antennas. ThereminAir maps that same gesture to your Apple Watch's motion sensors — so the motion of your hand, exactly like the original, becomes the music.
