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. Thirteen categories of original line art, from mandalas and stained glass to landscapes and fantasy scenes, with around 1,760 pictures to work through.
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.
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.
