# Zombie Fortress vs Cell to Singularity

The clearest difference is update cadence: Cell to Singularity at fortnightly against Zombie Fortress's every 26 months. Cell to Singularity also leads on ratings volume (23K vs 4) and review sentiment (82% vs 67%). Zombie Fortress's advantage is rating (5.0 vs 4.8) and iOS requirement (13.0 vs 15.0). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Zombie Fortress sells 7 one-off in-app purchases and Cell to Singularity sells 17 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Zombie Fortress holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Cell to Singularity has 23K ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 67% of Zombie Fortress's written reviews are positive against 82% of Cell to Singularity's, so the app with the better star average is not the one people write more warmly about.

Zombie Fortress ships an update every 26 months, Cell to Singularity fortnightly. The most recent releases landed on September 28, 2026 and October 1, 2026 respectively.
