TINT — Color Harmony Puzzle. A calm, offline color-gradient puzzle game for Android. Each board is a smooth color gradient generated mathematically on the device; some tiles are pinned, the rest are shuffled, and the player drags tiles onto each other (or taps two tiles) to swap them until the gradient flows again. 70 handcrafted levels across 7 chapters (Sunrise, Lagoon, Bloom, Neon, Pastel, Dusk, Mono), star ratings per level (1-3 stars based on move count), sequential level unlocking, a hint button with a 45-second cooldown, gentle synthesized sound effects and optional vibration. Completely free with NO ads, NO in-app purchases, NO accounts, NO sign-in. Fully offline: the app requests no permissions (vibration uses the standard web vibration API inside the packaged WebView), makes no network requests, and stores only local progress (earned stars, language EN/TR, sound and vibration preferences, onboarding-seen flag) in the WebView's localStorage on the device. No analytics, ads, or crash-reporting SDKs are included. Uninstalling the app deletes all stored data.
