# iO vs Lunar Lander Mission

The clearest difference is rating: Lunar Lander Mission at 4.4 against iO's 3.7. Lunar Lander Mission also leads on update cadence (every 8 days vs every 6 weeks) and ratings volume (169 vs 19). iO's advantage is review sentiment (71% vs 52%). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. iO sells 1 one-off in-app purchase and Lunar Lander Mission sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Lunar Lander Mission holds the better App Store score, 4.4 against 3.7. That said, the two scores are not equally well evidenced: Lunar Lander Mission has 169 ratings behind it against 19, so its average is the more settled of the two. Written reviews complicate that: 71% of iO's written reviews are positive against 52% of Lunar Lander Mission's, so the app with the better star average is not the one people write more warmly about.

iO ships an update every 6 weeks, Lunar Lander Mission every 8 days. The most recent releases landed on October 19, 2026 and October 24, 2026 respectively.
