Verdict
The clearest difference is rating: TerraGenesis at 4.2 against Space Simulator's 2.7. TerraGenesis also leads on review sentiment (50% vs 15%) and ratings volume (2K vs 93). Space Simulator's advantage is update cadence (every 9 days vs monthly). On price, ads, in-app purchases and monetization model there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Space Simulator sells 26 in-app purchases, starting at $2.99 per 7 days and TerraGenesis sells 12 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
TerraGenesis holds the better App Store score, 4.2 against 2.7. That said, the two scores are not equally well evidenced: TerraGenesis has 2K ratings behind it against 93, so its average is the more settled of the two. Written reviews point the same way: 15% of Space Simulator's written reviews are positive against 50% of TerraGenesis's.
Space Simulator ships an update every 9 days, TerraGenesis monthly. Both last shipped on October 24, 2026.
