Turn your facial expressions into sound. Quavery turns your iPhone into a face-controlled Theremin. Its TrueDepth camera tracks how you move your face and turns that movement straight into music. It's a fully touchless instrument, with nothing to learn but your own expression. HOW IT WORKS • Open your mouth to raise the pitch • Raise your eyebrows to bring up the volume • Stretch your mouth to add reverb • Stick out your tongue to add distortion • Look left to cycle through waveforms: sine, triangle, square, and sawtooth • Look right to cycle through pitch scales: continuous, pentatonic, and major Every control lives on your face, so once the camera is running, you never need to touch the screen to play. WATCH WHAT YOU'RE PLAYING A live status panel shows pitch, volume, reverb, and distortion as you shape them, so you can see exactly what your expression is doing to the sound. New to Quavery? A short control guide walks you through every expression before you start. PRIVATE BY DESIGN Your face never leaves your device. Quavery uses the camera to track your expression in real time, and nothing is ever recorded, stored, or sent anywhere. No account is required to use the app. FREE TO PLAY Quavery is free, with no ads. If you'd like to support development, there's an optional tip jar in Settings. Nothing is locked behind it. Requires an iPhone with a TrueDepth camera (iPhone X or later, excluding SE models). --- PRIVACY POLICY https://leomakkinje.nl/apps/quavery/privacy TERMS OF USE https://leomakkinje.nl/apps/quavery/terms APPLE EULA https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ ## Key features - Facial expression to sound control - Touchless instrument interface - Live status panel for sound visualization - Multiple waveforms and pitch scales - Privacy-focused design, no data sent - Built-in control guide ## Pricing and in-app purchases Base price: Free. **One-time purchases** | Purchase | Price | Type | | --- | --- | --- | | Small tip | $0.99 | one-time | | Medium tip | $2.99 | one-time | | Large tip | $4.99 | one-time | ## Recent user reviews (1 of 1) All indexed reviews: https://appshunter.io/ios/app/quavery-theremin/id6800290999/reviews.md ### 5/5 — A Salad of Fun Sounds *2026-09-10* "I was doodling with the sounds and created a nice little 5-6 second chant that sounded like a Native American flute melody. Very interesting how you created the imbedded sounds and they can be recreated in perfect notes like reading music as long as one duplicates the same exact facial expressions. Kind of like composing a melody but instead of writing it down you express it with intrinsic physical values instead." ## Frequently asked questions about Quavery Theremin ### What is Quavery?
