Pocket Reef is an aquarium that is actually alive. The water, the light and every fish are simulated on your phone in real time. Feed them from your hand, watch an octopus change colour, and see the water glow under a full moon.

How it works
Watch. Touch. Get to know them.
Other aquarium apps loop a video. Pocket Reef simulates every fish, every ripple and every ray of light, so nothing ever happens the same way twice.
Watch
Open the app and the tank is alive: neon tetras school, angelfish hover and watch you, clownfish keep to their anemone. At night they slow down and rest.
Touch the water
Tap to splash, drag to look around, pinch to get close enough to see the scales. Hold a finger still and the brave ones come to feed from your hand.
Get to know them
Every fish has a name, a personality and a mood. Feed them often and they learn to trust you, until they swim over to say hello when you open the app.
Inside the tank
Rendered live, never a picture
Every screen below is the app itself, drawn in real time. Swipe to see them all.
Sharks, whales and dolphins
Twenty-one sea creatures, scaled to fit. Big animals are part of Pro.
The octopus
It crawls, matches the sand, and inks if you startle it.
Hand-feeding
Hold still and they come. Trust grows every day.
After dark
Full-moon plankton, and a glowing trail behind your finger.
Six worlds
Coral reef, kelp forest, river, blackwater and more.
Design your tank
Place every plant and creature where you want it.
Every fish has a name
A mood, a personality, and trust you earn.
A book, not a grind
Rare moments and species to discover. No streaks.
See it move
Ambient mode turns your phone into a window on the reef
A slow, cinematic camera follows one fish, then drifts out across the tank.
The screen stays on and the controls get out of the way.
It runs at a calm frame rate, so it is easy on your battery.
The details
Small things that make it feel alive
A tank that keeps time
The light follows your clock from dawn to moonlight, and the moon's real phase decides when the water glows.
Rare moments
A sea turtle passing through, a storm overhead, a pearl in the giant clam, fry from a bonded pair, whale song at night.
Photos, clips, postcards
Photo mode with no buttons in the way, six-second clips with slow motion, and postcards of your favourite fish.
Good morning, reef
Each morning a dawn photo of your tank waits for you, with what happened while you were away.
Home-screen widget
A picture of your tank and its latest news, right on your home screen.
Liquid glass
Controls made of glass that bend the water behind them, with haptics for every splash and nibble.
Gentle on your phone
The tank slows down when nothing is happening, and backs off further if your phone gets warm or Low Power Mode is on.
Rearrange any time
Drag plants and creatures to a new spot on the sand, and undo if you change your mind.
Private by design
No accounts, no ads, no analytics. Your tank lives on your device.
