Verdict

The call

The clearest difference is rating: Zombies.io at 4.2 against Mars Survivors's 2.9. Zombies.io also leads on ratings volume (63 vs 9). Mars Survivors's advantage is review sentiment (50% vs 40%) and iOS requirement (13.0 vs 15.6). On price, update cadence, ads and in-app purchases there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Zombies.io holds the better App Store score, 4.2 against 2.9. That said, the two scores are not equally well evidenced: Zombies.io has 63 ratings behind it against 9, so its average is the more settled of the two. Written reviews complicate that: 40% of Zombies.io's written reviews are positive against 50% of Mars Survivors's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Zombies.io ships an update every 10 days, Mars Survivors every 11 days. The most recent releases landed on October 21, 2026 and October 24, 2026 respectively.
