# Universe Gravity Simulator 3D vs Earth Sandbox

The clearest difference is rating: Universe Gravity Simulator 3D at 4.0 against Earth Sandbox's 2.3. Universe Gravity Simulator 3D also leads on ads (none vs shown) and ratings volume (144 vs 12). Earth Sandbox's advantage is in-app purchases (none vs 1) and update cadence (weekly vs every 5 weeks). On price, review sentiment and device support there is nothing between them.

Both are free to download. Universe Gravity Simulator 3D sells 1 one-off in-app purchase. Earth Sandbox asks for nothing beyond the download.

Universe Gravity Simulator 3D holds the better App Store score, 4.0 against 2.3. That said, the two scores are not equally well evidenced: Universe Gravity Simulator 3D has 144 ratings behind it against 12, so its average is the more settled of the two. Written reviews complicate that: 43% of Universe Gravity Simulator 3D's written reviews are positive against 50% of Earth Sandbox's, so the app with the better star average is not the one people write more warmly about.

Universe Gravity Simulator 3D ships an update every 5 weeks, Earth Sandbox weekly. The most recent releases landed on November 12, 2026 and November 9, 2026 respectively.
