Every sound
has a shape.

Imajourn is a cymatics app for iPhone and iPad that turns sound into shape. Hum a note and the water settles into its pattern, touch it and every ripple plays a note, ring a plate of sand and watch it gather on the still lines, or see sound travel through a room in 3D.

Yes. It's free to download and play. Imajourn Pro is a one-time purchase, never a subscription, that adds Room in 3D, every shape and plate, your own words, photos and SVG files as shapes, all voices, scales and palettes, and longer clips without the mark.

Cymatics is the study of sound made visible: vibration arranging water, sand or light into patterns. Imajourn simulates the real wave physics, so each pattern is the shape that sound makes in that vessel.

In 1787 Ernst Chladni scattered sand on a metal plate and made it ring with a violin bow. The sand jumped away from the parts that moved and settled on the still lines, drawing a different figure for each note. Imajourn's Plate recreates this with thousands of grains.

Yes. As you play, Discoveries explains each wave effect you find in one line (reflection, interference, beats, resonance, the double slit and more), and you can draw walls, slits and lenses to show them. It's rated 4+ and needs no account.

Yes. Hum a steady note and watch the water settle, or start Drift, which plays by itself and fades to sleep on a timer (15 minutes free, longer with Pro). It's made for calm and curiosity; it isn't a health or therapy app.

It depends on the note you chant it on and the shape of the vessel, not on the word: the same note in the same vessel always draws the same shape. Turn on Hum, chant Om on one steady note and watch its figure form; change the note or the vessel and the figure changes.

The patterns are real wave physics. In a circle, hexagon or square they form the symmetric rosettes and mandalas often called sacred geometry, and Symmetry repeats each touch around the centre, up to eight times, to make your own.

As a visual sketchbook, yes. Room's live waves (Imajourn Pro) show a clap travelling, reflecting and building standing waves inside a sphere, cube, cylinder or a 3D model you import (USDZ, OBJ, STL or PLY). It shows how sound moves but doesn't measure it, so it isn't a substitute for acoustic engineering software.

Open the menu (the Imajourn mark, top left) and choose Imajourn Pro. It's a single purchase. On a new device, or after reinstalling, tap Restore Purchases in the same menu with the Apple Account you bought it with.

Imajourn needs the microphone for Hum and Listen. Check Settings → Privacy & Security → Microphone and make sure Imajourn is on. Then hum one steady note close to your device, away from loud noise.

In Water, open Touch and choose Wall, Lens or Sponge, then draw on the water. Choose Erase to rub out what you drag across, or tap Clear drawing to start again.

Open Room (Pro), choose Waves under Touch, then in Shape tap Import a 3D model. USDZ works best; OBJ, STL and PLY work too. Large scans take a few seconds to prepare. Tap to clap or to place singing sources inside it, and choose Shaded or Outline to see it your way.

Open the menu and tap Share to send the scene you're playing as a link, or share any scene you've kept in your Library. Anyone with Imajourn opens exactly the same scene; anyone without it is pointed to the App Store.

Yes. Open Control Centre, tap Screen Mirroring and choose your Apple TV or AirPlay TV. The TV shows only the canvas, and your device stays the instrument.

No. There's no account, no ads and no tracking. Sound from the microphone is analysed on your device and never recorded, and nothing you play leaves your device unless you share it yourself. The full policy is below.
