Two knobs.
One shake.
Endless doodles.

monoink brings the classic mechanical drawing toy to your phone — beautifully tactile, wonderfully pointless, impossible to put down.

Simple to pick up. Hard to put down.

Everything the classic toy did, rebuilt to feel great on glass.

Twist to draw

Two rotary knobs move the cursor left/right and up/down — exactly like the toy you remember, now smooth and precise.

Shake to erase

Give your phone a shake and the screen wipes clean — with a satisfying whoosh. No undo button, because commitment builds character.

Save & share

Snapshot your masterpiece to a personal gallery and share it straight to your friends. A small monoink.app tag comes off for a one-time $1.99.

Playful themes & pens

Five hand-tuned themes — Classic Red, Mint, Charcoal, Arcade and Blossom — each with a twelve-colour watercolour tray for your pen.

Free draw, trace & score

Break free of the knobs to sketch with your finger, or trace over 140+ built-in shapes across 9 categories — with a live accuracy score and a best-score to beat. All free.

Yours, everywhere

An optional account is there if you want it — it also carries your one purchase across devices. Your sketches stay private on your device — never uploaded.
