Color Tap vs pau.

Color Tap is a free color-by-numbers app that gives children a way to explore pixel art. Its library contains hundreds of pictures, with the press page counting more than 800 templates. The makers say they curated and licensed the artwork from pixel artists around the world. Pictures are bundled with the app and remain available offline after installation. In the painting area, touch controls where coloring happens, while the artwork's zoom level affects how much is filled at a time. The makers describe the experience as intended for children, including children with autism spectrum disorder, and cite playful visuals, animation, and sound design. Separate soundtrack versions are provided for headphone and non-headphone listening. The app is free to download, with all content included; the makers say it has no ads, in-app purchases, or subscriptions. They also say the iOS app neither tracks users nor collects data in the app. Color Tap is listed for iOS and macOS, though its download page points to the Apple App Store. The App Store names Great Scott AB as developer.

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.
