Zoom from a planet's surface out to distant galaxies, then reshape the whole system with your own hands. Solar System Sim is a real-time gravity sandbox built on Newton's laws and real astronomical data. Every body you add, move or destroy recalculates the orbits of everything else, live. • Smash worlds together: impact craters carve into the surface, firestorms sweep the globe, and glowing debris rains back down. • Build your own universe: add planets, moons, asteroids and comets with their own size, mass and looks, or customise the ones already there. • Land anywhere: drop to a first-person view on any planet's surface and experience its environment. • Sculpt rings: add particle rings and watch gravity shape them in real time. • Witness real eclipses: solar and lunar, with real-world astronomical precision. • Follow comets: watch them streak past and interact with the bodies they meet. • Leave the Solar System: travel to remarkable nearby stars and find them within the Milky Way. • Feel the scale: see the true vastness of space, from a pebble-sized moon to the nearest galaxies. Whether you're here to learn how gravity really works or just to break planets with it, explore at your own pace. Start your cosmic adventure with Solar System Sim.
World Destroyer Simulator
Read full descriptionHide full description
Pick a world. Pick a weapon. See what's left. World Destroyer is a sandbox where a planet floats in front of you and you take it apart. Tap to fire, drag to spin it, pinch to look closer. Each strike leaves a crater, the crust cracks and glows, the population ticks down, and eventually there is nothing left but a ring of rubble and a report of what you did. THIRTY-THREE WEAPONS Seven categories on the rail down the right edge. Meteors, storms, comets, an extinction-class asteroid and a moon dragged out of orbit. Lasers and a plasma lance you drag across the surface to carve molten scars. A black hole that stretches the world and swallows it. A supernova. A cleave that splits the planet in two along the line you tap. Saucers, a dreadnought, a strike wing and a drone swarm. A kraken, a world-eating worm, a void dragon and something ancient that opens its eye. Volcanoes, quakes, tsunamis, an ice age and a plague. And three ways to fight back: a shield, a guardian satellite and a terraformer that heals the crust. TEN WORLDS An Earth-like world of eight billion. A jungle super-earth. A red desert with domed colonies. An airless cratered moon. A banded gas giant with nothing to crater and everything to stir. A lava world already on fire. A frozen ocean with cities under the ice. A water world where the cities float. A ringed violet world. A volcanic-glass planet lit by neon cities. Every one is generated on your device, down to the coastlines, the clouds and the night-side lights. WATCH IT DIE Damage is not a number hidden somewhere. Craters have depth. Lava glows in the cracks and cools over time. The clouds darken, the atmosphere turns the colour of smoke, fissures race across the crust, and a world that has taken enough keeps losing people between strikes. Slow time down to watch a nuke go off, or speed it up to watch a plague spread. MADE ON YOUR PHONE There are no downloads and no assets. Every texture, every sky, every sound is synthesised when the app opens, which is why it is small and why it works with no connection at all. NOTHING ELSE No account, no sign-in, no ads, no purchases, nothing collected. Settings has a switch to reduce flashing for anyone sensitive to bright light.

Verdict
The clearest difference is in-app purchases: World Destroyer Simulator at none against Solar System Sim's 5. World Destroyer Simulator also leads on ads (none vs shown). Solar System Sim's advantage is iOS requirement (15.0 vs 17.0). On price and device support there is nothing between them.
