Free to start. Nothing to sign up for.

There is no account, no email, and no wall between you and the first model. Twelve artifacts are free, plus a new Model of the Day for everyone, every day. If you want the whole museum, there is a subscription — and if you don't, the app keeps working.

iPhone and iPad. Works offline after the first download.

No ads, not even rewarded ones

There is no advertising SDK in the app. Nothing to sit through before a color.

Nothing held hostage in the cloud

What you make is written to your device and stays there. Your stars and progress sync through iCloud — no sign-in.

No streaks to break

Reminders end by themselves. There is no score, no timer, and nothing to catch up on.

What it actually looks like

Real screens from the app, not mockups. Scroll sideways.

Free 3D painting: a chameleon character painted on one half, blank on the other, with crayon size, grain and opacity dials.

Three taps to the first color

No tutorial to sit through. The app is designed so the first stroke happens inside a minute of opening it.

1

Pick an artifact

Browse 250+ models by category, style or difficulty, or let Adventure mode deal you one. Tap download — the button tells you up front that it will then work offline.

2

Choose how to work on it

Every model does all three: free-paint it in 3D, shatter it into a jigsaw puzzle, or follow numbered slots. Same artifact, three completely different evenings.

3

Spin, paint, and stop whenever

One finger paints, two fingers orbit and zoom. It saves itself as you go, so you can close the app mid-stroke and pick the brush back up tomorrow.

The three modes, side by side

ModeWhat you doGood forLength
Color in 3D Free-paint the whole surface with twelve tools. Spin it, zoom in, color the back of its head. Making something that is yours. No right answer. 10 minutes to open-ended
Puzzle The model shatters along its own seams. Rebuild it and its colors come back. Wanting a problem, not a blank page. 20 pieces to 500
By numbers The same puzzle, with every empty slot numbered. Match and place. Pure flow. Nothing to work out. As long as you like

A real painting studio, not a fill bucket

Twelve tools — brush, pencil, marker, crayon, airbrush, spray, gradient, smudge, fill, eraser, colour picker and a zone selector. Size, opacity, hardness, grain and flow on each. Undo and redo up to 50 steps, or two-finger tap to undo and three fingers to redo.

Built for the Pencil, and for the couch

On iPad, strokes carry Apple Pencil pressure and tilt, your palm is told apart from the nib, and a hover cursor shows the brush before you touch down. Left- and right-handed layouts. Four quality tiers, from old phones to new ones.

Answers, before you install anything

Twelve guides on the things people actually ask before downloading a coloring app — what works without Wi-Fi, whether coloring does anything for anxiety, how a 3D coloring book differs from paper, and what a subscription does and doesn't buy.

Questions people ask first

Does Spin & Paint work offline?

Yes. Download a model once and it colors offline from then on — on a plane, on the metro, in a basement with no bars. Your gallery, saved colorings and puzzles in progress all open in airplane mode. The one exception: a puzzle needs a single connected moment the first time you open it, to fetch the artifact's original colors. After that it plays anywhere.

Is Spin & Paint free?

It is free to download and free to use. Twelve artifacts across ten halls are free, and a new Model of the Day is free for everyone, every day. An optional subscription opens the whole museum — every artifact, at maximum detail, in all three modes.

Learn more about what's free and what isn't →

What is a 3D coloring book?

A 3D coloring book gives you a sculpture instead of a flat outline. You spin the model with your finger to reach every side, and paint directly onto its surface — the back of its head, the inside of a wing, the sole of a shoe. There are no lines to stay inside, because there are no lines.

Does it work with Apple Pencil?

Yes, properly. Strokes carry Apple Pencil pressure and tilt, a hover cursor shows your brush footprint before you touch down, your resting palm is told apart from the pencil, and the system "Only Draw with Apple Pencil" setting is respected.

Learn more about Apple Pencil support →

Are there ads?

No. There is no advertising SDK in the app at all — no rewarded video before a color, no interstitial between puzzle pieces, nothing to wait out. With signal or without.

Learn more about ad-free coloring apps →

Can you color by number?

Yes. By numbers is one of the three modes every model supports. The model breaks into pieces along its own seams and every empty slot is numbered, so there is nothing to work out — just match the number and place the piece.

Learn more about color by number in 3D →

Does coloring actually reduce anxiety?

Published studies on structured coloring — mandalas in particular — have found that short sessions reduce self-reported anxiety more than free-form drawing does. The effect appears to come from structure: a defined task occupies attention without demanding decisions. It is a wind-down, not a treatment.

Learn more about the research →

Does it work on iPad?

Yes. iPad runs full-screen in landscape with the same twelve tools and full Apple Pencil support. Your stars, settings and puzzle progress follow you between devices through iCloud, with no account to create. Finished paintings stay on the device that made them.

Learn more about Spin & Paint on iPad →

How do I save or share what I've painted?

Every coloring and every puzzle saves itself as you work, so you can close the app mid-stroke. When you're finished you can save the piece to Photos, or share a spinning video of it that shows all sides.

Learn more about saving and sharing →

How many models are there?

Over 250, arranged across 42 halls — dragons, demons, idols, animals, robots, food, spaceships and spirits, sorted by category, style and difficulty. New ones arrive regularly, and Adventure mode deals you one a day.
