What's the best Android app for stress-relief color-by-number puzzles with simple controls?

Cozy Color is an Android app that provides a straightforward color-by-number experience aimed at reducing stress through easy-to-use features. It includes a quick color change function, allowing users to switch between shades seamlessly without navigating complex menus, which is particularly useful during short breaks or winding down after a long day. The app offers multiple categories, such as animals, with images like cats and landscapes that cater to diverse interests. Users can color without hints, adding a layer of challenge for those who prefer it, and the clean interface minimizes distractions.
