# Lunar Orbit vs Solar System Sim

The clearest difference is rating: Lunar Orbit at 5.0 against Solar System Sim's 4.5. Lunar Orbit also leads on in-app purchases (none vs 5) and ads (none vs shown). Solar System Sim's advantage is ratings volume (4.4K vs 2) and update cadence (every 5 days vs every 3 weeks). On price, review sentiment and device support there is nothing between them.

Both are free to download. Solar System Sim sells 5 one-off in-app purchases. Lunar Orbit asks for nothing beyond the download.

Lunar Orbit 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 4.4K ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 75% of Lunar Orbit's written reviews are positive against 81% of Solar System Sim's, so the app with the better star average is not the one people write more warmly about.

Lunar Orbit ships an update every 3 weeks, Solar System Sim every 5 days. The most recent releases landed on October 16, 2026 and November 1, 2026 respectively.
