Scribble with one finger.
The whole screen goes wild.

Every mark you make is mirrored around the middle, so a single lazy squiggle comes back as a kaleidoscope of light. There is no skill to learn and no wrong way to do it. You drag, it blooms.

Coming soon to the App Store

Free. No account, nothing to buy, and nothing you draw ever leaves your device.

Draw something right now

One finger, multiplied

Choose how many times the screen folds, anywhere from a plain mirror up to sixteen ways at once. Low folds feel like drawing. High folds feel like the screen is doing it with you, and the same scribble becomes a completely different thing.

Seven brushes, fourteen palettes

Silk draws long ribbons of light. Bloom throws petals. Prism splits everything into colour. The palettes run from deep neon on black to soft ink on paper, so the app can be a dark room at night or a bright sheet in the morning.

A small cast turns up

Little creatures drift into the picture and get caught in the symmetry with everything else, so a ring of them ends up orbiting whatever you drew. They are not a menu you have to open. They just arrive, and you meet more of them the longer you play.

Tilt it, then keep it

Switch on Tilt 3D and the picture moves with your phone, the way a depth photo does, no glasses and no crossed eyes needed. When you like what is on screen, one tap saves it to your photos at full size with none of the buttons in the way.

A closer look

Real screens, drawn by dragging one finger across the glass.

A teal kaleidoscope of small cats at six folds — One squiggle, mirrored six ways

A dense sixteen fold bloom ringed with gold starbursts — Sixteen folds, and the screen fills with light

Yours, on your device

oomoomoo has no accounts and no server holding your work. Every picture you keep and every setting you change lives in your phone's own storage. We never see what you draw, never sell anything, and never show ads, and the app ships a policy that switches the camera, the microphone, and location off at the browser level rather than just promising not to use them. The full policy is at svltmk.com/oomoomoo/privacy.

On a desktop? Point your phone camera here and oomoomoo opens on your phone right now. Add it to your home screen and it lives there like any app.

Be first to know

The App Store version is on its way. Leave your email and we will send you one message, once, on the day it goes live. That is the only reason we would ever write to you.
