The maker says its library contains over 50,000 pictures from artists around the world, with categories including Disney, mandalas, mystery pictures, postcards, pixel art, flowers, nature, places, animals, and art. A search tool helps locate pictures by topics such as hobbies and interests. The digital coloring content is free of charge. Happy Color is listed for Android, iOS, and the web, while the FAQ specifies smartphone and tablet support and excludes laptops and desktop computers. Pictures in My Feed can be colored without internet, but full offline mode and every feature are unavailable.

Premium options are $9.99 a month or $49.99 a year in the US App Store.

pau. is a minimalist adult coloring app for iPad, with hand-drawn pages, freeform coloring, and optional Apple Pencil support. Its free plan provides Fill, Soft Round, Fineliner, Marker, undo and redo, stroke adjustments, an eyedropper, and recent colors. Premium adds watercolor, oil, gouache, pastel, and chalk brushes, plus Smudge. It also unlocks reusable custom palettes, palettes made from photos, the full page library, and exports without the pau. mark. The maker says about four new hand-drawn pages arrive each Friday. Progress saves automatically on the iPad, and downloaded pages remain usable offline. Finished images and automatic time-lapse videos can be saved. The maker says there are no accounts, ads, or cross-app tracking; its policy describes pseudonymous events through TelemetryDeck and diagnostics through Sentry. An eligible non-subscriber can preview Premium brushes and Smudge once for 72 hours. The app requires iPadOS 18.6 or later.
