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 rating: Pixel Cave 2018 at 5.0 against Solar System Sim's 4.5. Pixel Cave 2018 also leads on in-app purchases (none vs 5) and ads (none vs shown). Solar System Sim's advantage is update cadence (every 3 weeks vs every 27 months) and ratings volume (4.1K vs 6). On price, review sentiment and device support there is nothing between them.

Both are free to download. Solar System Sim sells 5 one-off in-app purchases. Pixel Cave 2018 asks for nothing beyond the download.
Pixel Cave 2018 holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: Solar System Sim has 4.1K ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 75% of Pixel Cave 2018's written reviews are positive against 80% of Solar System Sim's, so the app with the better star average is not the one people write more warmly about.
Pixel Cave 2018 ships an update every 27 months, Solar System Sim every 3 weeks. The most recent releases landed on August 12, 2026 and September 24, 2026 respectively.
