Colouring in, without the crayons under the sofa.
Tintl is a therapeutic colouring app for iPad: tap a region and it fills, or pick up a brush and paint inside the lines — the lines hold. Fifteen categories of original line art, mandalas and stained glass through to ocean scenes and space, with 1,762 pictures to work through. Live now on the App Store.
Four brushes
Fill for instant colour, a soft airbrush that builds as you go, a pencil with real tips and pressure, and an eraser that behaves like paper. Every stroke stays inside its region.
Palettes worth keeping
Curated palettes — Dawn, Meadow, Ocean, Blossom, Slate — plus your own custom sets, so a picture hangs together even if you never think about colour theory.
Free to start
The app is free, and the opening pictures of every category are free with it, so you can try all fifteen styles before spending anything. Volumes of forty pictures are £0.99 each, or £9.99 unlocks the lot, future volumes included. No subscription.
Calm by design
No timers, no streaks, no adverts between pictures. Finish a piece and the app marks the moment quietly, then lets you carry on.
