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.

Verdict

The call

The clearest difference is in-app purchases: SkySling at none against Solar System Sim's 5. SkySling also leads on ads (none vs shown) and update cadence (daily vs every 4 days). Solar System Sim's advantage is device support (3 vs 1) and iOS requirement (15.0 vs 26.2). On price there is nothing between them.
