Paintkin

Paintkin is a calm, hands-on coloring space made for children ages 2–5 and their families. Children color with a finger or stylus—one stroke at a time, without tap-to-fill shortcuts. Every stroke is saved locally in its original order and timing. Parents can create separate profiles, resume drafts, celebrate finished artwork, replay the creative process, and share a private story through the system share sheet. • 168 child-friendly coloring pages across animals, vehicles, food, dinosaurs, ocean life, nature, space, fairy tales, everyday life, toys and music, farms, and active play • 12 free pages, with one free page in every theme • One optional, one-time purchase unlocks the remaining 156 pages • Hands-on coloring with undo, redo, eraser, brush sizes, and color references • Separate local profiles, drafts, galleries, and milestones for each child • Stroke-by-stroke replay with pause, scrubbing, and 1×/2×/4× speed • Parent-confirmed artwork and MP4/GIF story sharing • Privacy-first sharing: child details are excluded by default and can only be added by a parent for each share • No third-party ads, analytics SDKs, chat, or public gallery • No child account required; artwork stays on the device unless a parent chooses to share it
