Most live wallpapers on Android are just blurry video loops packed with tracking and excessive ads. I built Pet Shark to be a true, real-time 3D ocean simulation that lives right behind your home screen icons and doubles as a relaxing full-screen virtual aquarium. Every movement is driven by live physics and predator AI, no pre-recorded animations.

Double-tap your wallpaper anytime without opening an app to drop fish into the tank and watch your Great White or Hammerhead shark circle, stalk, and strike. Drop a handful of fish at once to trigger an aggressive Frenzy Feed, or tap the screen to call your shark right up to the glass. What makes Pet Shark different:

- Local Day/Night Sync: Transitions naturally from bright daytime sunbeams to deep-sea night lighting based on your local time.

- Battery-Smart Engine: Instantly freezes rendering the millisecond your screen turns off or another app covers the wallpaper, with custom 40/60/120 FPS modes.

- 100% Private & Offline: Zero ads, zero data tracking, and a simple one-time upgrade option instead of subscriptions.
