monoink

Two knobs. One shake. Endless doodles.

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

Twist the left knob to move horizontally, the right to move vertically. One continuous line, no lifting, no undo. Then shake your phone and the screen wipes clean with a satisfying whoosh.

TWIST TO DRAW
Two rotary knobs move the cursor exactly like the toy you remember — now smooth, precise, and responsive on glass.

SHAKE TO ERASE
Give it a shake and it's gone. No undo button, because commitment builds character.

140+ SHAPES TO TRACE
Nine categories to browse and filter — Shapes, Symbols, Nature, Animals, Objects, Vehicles, Landmarks, Alphabets and Numbers. Every shape scores your accuracy live and saves your best run to beat. All free.

FREE DRAW
Break away from the knobs and sketch with your finger when you want the line to go where you tell it.

FIVE THEMES, TWELVE COLOURS
Classic Red, Mint, Charcoal, Arcade and Blossom — each with a full twelve-colour watercolour tray for your pen. Arcade puts yellow on black. All five are free.

YOUR PRIVATE GALLERY
Snapshot your masterpiece and keep it in a personal gallery, framed in the theme you drew it in. Share it straight to your friends. Your sketches stay on your device — never uploaded.

ENGRAVE YOUR NAME
Put your name on the board, like the sticker on the original.

EVERYTHING'S FREE. ONE TINY EXTRA.
Knob drawing, shake-to-erase, free draw, all 140+ trace shapes with accuracy scores, name engraving, gallery, sharing, all five themes and the full pen tray — free.

The only purchase is removing the small monoink.app tag from shared images: $1.99, one time. No subscription. Nothing renews, ever.

An optional account is there if you want it — it carries your one purchase across devices. It's not required to use anything.

Simple to pick up. Hard to put down.
