Throw more fish.
Watch the shark go into a frenzy.

Pet Shark isn't a pre-rendered loop. Reactive predator AI stalks, circles and bites in real time, and every fish has its own speed, agility and intelligence.

1

Throw

Double-tap your wallpaper or the app view to drop in fish and start a chase on the spot.

Double-tap feeding
2

Hunt

Your shark stalks, circles and strikes with real jaw and bite mechanics. The fish fight back with swift dashes, zig-zag escapes and smart schooling.

Reactive AI, smart prey
3

Frenzy

The more fish in the water, the faster and more aggressive the shark becomes, with tighter attack angles as the pack grows.

Frenzy Feed mode

Choose your shark

Same hunt, different temperament. Both swim with natural water drag and banking turns.

The classic

Great White

The original Pet Shark. A powerful apex predator with real swimming momentum that stalks, circles and strikes.

Stalks, circles, strikes
The fast one

Hammerhead

Faster, more aggressive and sharper in the turns. It banks through the water to catch fast-dashing prey and makes every frenzy more intense.

Faster, more agile, more aggressive

Questions, answered

What is Pet Shark?

Pet Shark is a free 3D shark live wallpaper, virtual pet aquarium and shark simulator for Android. Choose a Great White or Hammerhead that hunts fish in real time, then run it as your system wallpaper or open it as a full-screen aquarium.

Is Pet Shark free? What does the unlock do?

Pet Shark is free to use. Every start begins with 4 fresh fish, and 200 double-tap throws are included to add extra fish and trigger Frenzy Feed. After that, your shark keeps hunting, cruising and answering your summon. One optional one-time purchase unlocks unlimited double-tap throws (no subscription).

How do the fish throwing and shark AI work?

Double-tap your wallpaper or the app view to spawn new fish and start a chase. The shark runs on reactive predator AI, so it stalks, circles and strikes in real time. Every fish has its own speed, agility and intelligence, which gives you swift dashers, zig-zag escapes and smart schooling. The more fish in the water, the more aggressive the shark gets.

How does day & night sync work?

When it is enabled in Settings, Pet Shark follows your phone's local time. The underwater scene moves between bright sunlit water during the day and deep-sea nocturnal lighting at night.

Does it work on the lock screen or as a desk display?

Yes. Apply it to Home and Lock Screen and the shark keeps swimming on your lock screen, with touch feeding disabled so pocket taps do nothing. In the standalone full-screen aquarium you can turn on Keep Screen Alive for continuous desk or tablet viewing.

Which frame rate should I choose?

60 FPS is the default and keeps animation fluid without warming your phone or draining the battery. 45 FPS saves extra battery and suits older phones and tablets. 120 FPS is ultra-smooth on high-refresh flagship displays, but it uses the most power and is mainly meant for the full-screen aquarium.

Will it drain my battery as a live wallpaper?

It is designed not to. Rendering pauses as soon as your screen turns off or another app covers it, so the 3D engine isn't running when you can't see it. Choose 45 FPS in Settings for even longer battery life.

Are there really no ads and no tracking?

Yes. The Pet Shark Android app has zero advertisements, no analytics, no location tracking and no personal data collection, and it works fully offline. A connection is only used if you buy the optional unlock. The Pet Shark website uses Google Analytics to measure website traffic.
