Start with a bare rock. Add oceans, raise mountains, plant forests, tune the atmosphere — then watch a real climate model decide what lives there.
A whole world fits in your hand.
Tiny Knowledge hands you a small, silent planet and a set of tools. Pour an ocean into a basin. Push a mountain range up along a coast. Scatter forests, warm the air, call down rain. Then let go and watch: the climate keeps running whether you touch it or not, and every choice you made turns into weather, biomes and life.
A SIMULATION, NOT AN ANIMATION
Every one of the 512 surface cells carries its own elevation, temperature, moisture, ice, vegetation and biology. Sunlight arrives by latitude, oceans store heat and release it slowly, mountains wring rain out of the wind and leave deserts behind them, forests pull carbon down and albedo pushes it back. Nothing is scripted. If your world turns into a frozen shell, it is because the numbers took it there — and you can pull it back.
TOUCH THE PLANET
Turn the globe with one finger and pinch to move closer. Tap any point to inspect it, or paint it with nine tools: ocean, mountain, forest, rainfall, warming, cooling, seeded life, levelling and inspection. Brushes fall off across the curve of the sphere, so terrain comes out organic rather than blocky. Five map layers let you read the same world as terrain, temperature, moisture, relief or biosphere.
WATCH IT COME ALIVE
Life moves through seven stages, from sterile rock to microbes, algae, flora, fauna, complex ecosystems and finally civilisation — whose city lights appear on the night side as the planet turns. Clouds drift and thicken with humidity. Ice caps advance and retreat. Volcanoes smoke. Ringed worlds cast their rings in front of and behind the globe, and moons orbit in real time.
FOUR WAYS TO PLAY
Relax: no failure, no timers, generated ambient sound tuned to your planet's temperature and biomass. Creative: unlimited energy and every tool open. Challenge: ten objectives with real conditions to satisfy. Scientific: the full instrument panel, with charts for temperature, coverage, atmosphere and biome share.
EIGHT KINDS OF WORLD
Begin on a temperate world and unlock oceanic, arid, frozen, volcanic, ringed, tidally locked and shattered planets by completing objectives. A tidally locked world has a permanent day side and a permanent night side, and the climate model treats it accordingly.
A CODEX WORTH READING
Twenty-four discoveries unlock as your planet earns them, each with a short, accurate note on the real science behind it — the runaway greenhouse, rain shadows, thermohaline circulation, the Great Oxidation Event. Twenty-six awards, ten reference notes and a full timeline of your world's history sit alongside them.
MADE TO BE CALM
Deep space backdrops, drifting nebulae, soft atmospheric scattering and a generated soundscape that mixes with your own music. No timers, no energy that runs out overnight, no notifications begging you to come back.
PRIVACY
No accounts, no tracking, no analytics, no ads. Your planets are saved on your device and never leave it. Tiny Knowledge works fully offline.
