# Galaxy Space Simulator 3D vs Solar System Sim

Galaxy Space Simulator 3D and Solar System Sim both sit at 4.4 stars, but that hides the real split: 80% of Solar System Sim's written reviews are positive against 40% of Galaxy Space Simulator 3D's. Solar System Sim also leads on update cadence (every 3 weeks vs every 5 months) and ratings volume (4.1K vs 457). Galaxy Space Simulator 3D's advantage is ads (none vs shown) and iOS requirement (12.0 vs 15.0). On price, rating, in-app purchases and monetization model there is nothing between them.

Both are free to download. Galaxy Space Simulator 3D sells 13 one-off in-app purchases and Solar System Sim sells 5 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.4 for Galaxy Space Simulator 3D against 4.5 for Solar System Sim. That said, the two scores are not equally well evidenced: Solar System Sim has 4.1K ratings behind it against 457, so its average is the more settled of the two. Written reviews are what separate them: 40% of Galaxy Space Simulator 3D's written reviews are positive against 80% of Solar System Sim's.

Galaxy Space Simulator 3D ships an update every 5 months, Solar System Sim every 3 weeks. The most recent releases landed on September 19, 2026 and September 24, 2026 respectively.
