Allok: Tap-to-Fill Coloring for Parents

Field notes

Allok maps each color to a number and highlights the areas associated with the selected palette entry, reducing coloring to a sequence of large, forgiving taps. The site names hwatu, minhwa, and nostalgic images as its initial subject matter, and says completed pictures can be saved and sent to children through KakaoTalk. It is presented as a free Android app with small advertising surfaces and no account or personal-information requirement.
