Pet Shark

Pet Shark is a free, interactive 3D virtual pet aquarium and live wallpaper for Android. Driven by a reactive predator AI rather than a pre-rendered loop, the shark dynamically stalks, circles, and hunts fish in real time. Users can double-tap their home screen to spawn prey, triggering an aggressive "Frenzy Feed" mode. Built to be highly efficient, it features a smart-pause engine that stops rendering when the screen is off to protect battery life. Best of all, it features zero ads, zero tracking, and full offline capabilities.
