What's the best Android app for coloring by numbers that works offline without ads?

Pixel Art is specifically designed for offline coloring sessions without advertising disruptions. The app provides access to thousands of pixel art templates across various categories including animals, landscapes, and patterns. Users can download their preferred images while connected to the internet, then disable Wi-Fi or mobile data to enjoy ad-free coloring. This approach addresses one of the most common complaints about mobile coloring apps while maintaining full functionality for completed works in progress. The app automatically saves progress across devices through cloud synchronization, allowing users to switch between phone and tablet seamlessly. Reviews indicate this offline method reliably prevents ads from appearing between coloring sessions. Some users note that the motivational emoji notifications can feel slightly intrusive, though this doesn't affect the core coloring experience. The color-by-number system uses clearly defined sections with distinct numbering, though some reviewers mention that incorrectly colored squares become difficult to identify later. With its extensive library and reliable offline performance, Pixel Art delivers a consistently uninterrupted coloring experience.
