# Universe Gravity Simulator 3D vs Space Crash Simulator

The clearest difference is review sentiment: Space Crash Simulator at 81% against Universe Gravity Simulator 3D's 43%. Space Crash Simulator also leads on rating (4.5 vs 4.0) and update cadence (every 5 days vs every 5 weeks). Universe Gravity Simulator 3D's advantage is ads (none vs shown) and iOS requirement (12.0 vs 15.0). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Universe Gravity Simulator 3D sells 1 one-off in-app purchase and Space Crash Simulator sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Space Crash Simulator holds the better App Store score, 4.5 against 4.0. That said, the two scores are not equally well evidenced: Space Crash Simulator has 723 ratings behind it against 142, so its average is the more settled of the two. Written reviews point the same way: 43% of Universe Gravity Simulator 3D's written reviews are positive against 81% of Space Crash Simulator's.

Universe Gravity Simulator 3D ships an update every 5 weeks, Space Crash Simulator every 5 days. Both last shipped on October 25, 2026.
