Users can color and recolor pictures and share finished creations on major social networks. The app is listed as a single-player game that works offline, so coloring does not require an internet connection. It is available on Android, Windows, iPhone, and iPad; the iOS listing requires iOS 13 or iPadOS 13 or later. The free plan offers coloring pages and contains ads. In-app subscriptions are listed at $4.99 a month, $9.99 a month, and $49.99 a year. Google Play reports no third-party data sharing, possible collection of location, app activity, and two other data types, encryption in transit, and an option to request data deletion.

PixelZen is an iOS color-by-number app built around pixel-art canvases. Its numbered coloring mode rejects incorrect-color taps instead of leaving them in place. Pix’s Workshop turns a typed prompt or uploaded photo into a numbered pixel canvas, using one to three orbs per generation according to difficulty. The app includes themed collections of hand-picked canvases; new books arrive regularly, most are free, and some unlock with gems. A shared daily canvas provides a bonus reward and a separate streak, while login streaks can survive missed days. Hint, Bucket, Bomb, and Prism each provide one free charge daily. Premium adds unlimited power tools and Instant Finish. Completed canvases replay the coloring journey and can be saved or shared as high-resolution art. Guests can play without accounts, or sign in with Apple, Google, or email to keep progress across devices. Internet access is required, with no offline mode. The free plan costs nothing; Premium costs $9.99 a month.
