Cymatics Art: Sound Patterns

Cymatics Art turns your phone into a Chladni plate: a plate covered in sand that you play with sound. Each note makes the plate vibrate in its own shape, and the sand jumps off the moving parts and gathers on the still lines, drawing the pattern. Change the note and the sand rearranges itself.

Free to use. Pro is a one-time unlock, with no subscription.

Play it with your voice
Hum, sing, whistle or play an instrument near your phone. The app hears the pitch and loudness and moves the sand to match. Louder sound shakes it harder; go quiet and the pattern stays put.

Or play a tone
Slide through the notes from 80 to 1000 Hz and hear the tone as the sand moves. Higher notes draw busier patterns.

84 patterns on three plates
Square, circle and violin shaped plates, each with 28 patterns that blend from one to the next as the pitch changes.

Six looks
Chladni Sand, Liquid Ripple and Lattice Glow, plus Aurora Plate, Ember Sand and Crystal Lattice in Pro.

Save clips and images
Save clip keeps the last few seconds of the plate, just as you saw it, with the sound, and puts it in your gallery. Save image keeps the plate as it is now.

Free, with a one-time Pro unlock
Free: the square plate, three looks, 5 second clips in 720p with a small watermark, and images with a watermark.
Pro: the circle and violin plates, three more looks, your own sand colour, clips up to 30 seconds in 1080p with no watermark, and full-size images. One-time purchase, no subscription.

Your sound stays on your phone. The app works offline and needs no account.

A note on accuracy: the patterns come from the maths of vibrating plates, not from one real plate, so the pitches will not match a plate on your desk. It is a sound art toy, not a lab instrument.
