Cell Zoo - Physarium

2.0 is (a)live: evolving colonies sing with Colony Voice and grow into your photos. Hatch a new creature every day and share by link

The most beautiful cellular automata simulator on iOS.

Watch alien organisms evolve in real time. Touch them, breed them, teach them to sing. Place them on your desk in AR. Cell Zoo is a pocket terrarium for mathematical life.

TEN LIVING WORLDS Slime molds that solve mazes. Continuous creatures that swim, split, and breathe. Chemistry that paints leopard spots and coral. Electromagnetic waves, self-assembling DNA, even your own words dissolving into life. Every world runs real math at up to 120 frames per second, and none of them behaves the way you expect.

IT GROWS INTO YOUR PHOTOS Hand the colony a picture and watch it grow into the bright shapes — your face, your handwriting, your dog. A living sketch, not a copy.

IT LISTENS. IT SINGS. Turn on Hearing and the colony moves to your music: bass makes it surge, treble makes it shimmer. Turn on Voice and the simulation sings back — a generative soundtrack drawn from the colony's own rhythms, never the same twice.

A NEW CREATURE EVERY DAY Hatch the Daily Specimen each morning. Race the Gauntlet — one maze a week, the same map for every player on Earth. Creatures you keep sync across your devices with iCloud.

SHARE WHAT YOU GROW Send any creature by link. It hatches on your friend's device exactly as you made it — same genes, same colors, same behavior.

BREED THEM (Premium) Cross two creatures and hatch the offspring. Mutate genomes. Pit colonies against each other in the arena and carry the winner's line forward.

30+ RENDER MODES (Premium) Photoreal protoplasm, holographic diffraction, infrared, liquid metal, bioluminescent deep-sea glow, aurora, soap film. Every mode is a handcrafted Metal shader.

AR MODE (Premium) Grow a colony on your table, floor, or wall. In 3D, a living structure floats in your room — walk around it. Walk through it.

TUNE EVERYTHING Sensor angles, diffusion rates, decay, species counts — every slider changes behavior live, and all of them are free. Capture the results in photo mode with pro exposure and cinematic filters.

Built native with Metal: 120Hz ProMotion, HDR bloom, MetalFX upscaling. No accounts, no ads, no analytics. Premium is a single one-time purchase.
