# Planet simulation vs Galaxy Space Simulator 3D

The clearest difference is rating: Galaxy Space Simulator 3D at 4.4 against Planet simulation's 3.9. Galaxy Space Simulator 3D also leads on ads (none vs shown). Planet simulation's advantage is in-app purchases (none vs 13) and review sentiment (74% vs 40%). On price, ratings volume, update cadence and device support there is nothing between them.

Both are free to download. Galaxy Space Simulator 3D sells 13 one-off in-app purchases. Planet simulation asks for nothing beyond the download.

Galaxy Space Simulator 3D holds the better App Store score, 4.4 against 3.9. Both are backed by a comparable volume of ratings — 164 and 457 respectively. Written reviews complicate that: 74% of Planet simulation's written reviews are positive against 40% of Galaxy Space Simulator 3D's, so the app with the better star average is not the one people write more warmly about.

Planet simulation ships an update every 7 months, Galaxy Space Simulator 3D every 5 months. Both last shipped on September 19, 2026.
