About

Uchinomon

Features
Read full description

Uchinomon turns your child's drawing into a living monster — entirely on your device. HOW TO PLAY 1. Snap a photo of a drawing (or pick one from your library) 2. On-device magic cuts out the shape and brings it to life as a monster 3. Give it a name and welcome it to your own zoo 4. While you're away, your monsters go on little adventures and find souvenirs. Next time you open the app, new "welcome back" discoveries are waiting DESIGNED FOR PEACE OF MIND • Your child's drawings, names, and data never leave the device — everything is processed locally and protected by iOS encryption. Delete the app and it's gone • No ads • Sign-ups and purchases sit behind a parent gate (Face ID etc.) PRO (one-time purchase) One payment unlocks unlimited drawing imports, permanent zoo cards, and a permanent discovery log. No subscription. For kids aged 3-6 and their grown-ups to enjoy together. Please note: the app's interface is currently in Japanese (simple kana). The gameplay is visual and works great without reading — many families enjoy it as-is — but menus are not yet in English.
