# Spaceman vs Solar System Sim

The clearest difference is rating: Spaceman at 5.0 against Solar System Sim's 4.5. Spaceman also leads on iOS requirement (11.0 vs 15.0). Solar System Sim's advantage is ratings volume (4.3K vs 3) and update cadence (every 4 days vs every 2 weeks). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Spaceman sells 1 one-off in-app purchase and Solar System Sim sells 5 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Spaceman holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: Solar System Sim has 4.3K ratings behind it against 3, so its average is the more settled of the two.

Spaceman ships an update every 2 weeks, Solar System Sim every 4 days. The most recent releases landed on October 13, 2026 and October 19, 2026 respectively.
