# Universe Gravity Simulator 3D vs Space Sandbox

The clearest difference is review sentiment: Space Sandbox at 100% against Universe Gravity Simulator 3D's 43%. Space Sandbox also leads on in-app purchases (none vs 1). Universe Gravity Simulator 3D's advantage is rating (4.0 vs 3.2) and ratings volume (142 vs 6). On price, ads and device support there is nothing between them.

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

Universe Gravity Simulator 3D holds the better App Store score, 4.0 against 3.2. That said, the two scores are not equally well evidenced: Universe Gravity Simulator 3D has 142 ratings behind it against 6, 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 100% of Space Sandbox's, so the app with the better star average is not the one people write more warmly about.
