Udraw
A simple, clear, ad-free drawing app for children aged 3 to 10. 100% offline.
No accounts, no ads, no data collection. One Flutter codebase runs on Windows, macOS, Android, iPad and iPhone.
Features
Free drawing
Marker and chalk inks, a 25-color palette, five brush sizes, eraser, undo/redo and clear-all. Strokes smoothed with Bézier curves, and the last brush is remembered per drawing.
Magic brushes
Four playful effects that ignore the chosen color: rainbow, neon glow, sparkle trail and pastel ribbon, shown as gradient swatches in the palette.
Line styles & shapes
Line patterns (solid, dotted, dashed, dash-dot) and a straight-line tool that snaps new lines to nearby endpoints to build clean geometric shapes. Paint bucket fills a closed area or the whole page, in a solid color or with a magic effect.
Coloring mode
70+ line-art models drawn entirely in code (zero assets): animals, vehicles, scenes, space, plus art-style models inspired by Mondrian, Kandinsky, Klee, Matisse, Picasso, Chagall, Basquiat, Calder and Dalí. Offline theme search, surprise and mix buttons, procedural generators.
Stickers & gallery
A catalog of ~40 emoji stamps sized to the brush. Drawings are saved automatically and shown as thumbnails in a responsive grid.
Built for kids
Four UI themes (light, dark, night, unicorn), one-tap fullscreen, a compact toolbar, a UI that adapts from small phones up to 4K (resizing zooms the whole drawing), bilingual FR/EN, and above all: no ads, no tracking.
