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 clearest difference is in-app purchases: Force of Gravity at none against Solar System Sim's 5. Force of Gravity also leads on ads (none vs shown) and update cadence (daily vs every 5 days). Solar System Sim's advantage is ratings volume (4.4K vs 2) and device support (3 vs 1). On price and rating there is nothing between them.

Both are free to download. Solar System Sim sells 5 one-off in-app purchases. Force of Gravity asks for nothing beyond the download.
On the App Store both sit at effectively the same score — 4.5 for Force of Gravity against 4.5 for Solar System Sim. That said, the two scores are not equally well evidenced: Solar System Sim has 4.4K ratings behind it against 2, so its average is the more settled of the two. Written reviews are what separate them: 100% of Force of Gravity's written reviews are positive against 81% of Solar System Sim's.
Force of Gravity ships an update daily, Solar System Sim every 5 days. The most recent releases landed on October 29, 2026 and October 30, 2026 respectively.
