Easy enough for little hands
No reading needed. Three moves and you're coloring.
Tap or paint
Tap to fill a whole shape, or scribble freely — the paint never leaks over the black lines.
Spin & zoom
Two fingers turn the room and zoom in, so you can color behind the sofa and under the table.
Ten rooms to fill with color
Every object is its own little coloring page — cups, cats, cranes and all.
👆 Tap a room to color it in. Tap again for a fresh page.
