# Zombie Outbreak Simulator vs Infection Bio War

The clearest difference is ads: Infection Bio War at none against Zombie Outbreak Simulator's shown. Infection Bio War also leads on rating (4.6 vs 4.1) and update cadence (every 3 weeks vs every 3 months). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Zombie Outbreak Simulator sells 10 one-off in-app purchases and Infection Bio War sells 10 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Infection Bio War holds the better App Store score, 4.6 against 4.1. That said, the two scores are not equally well evidenced: Infection Bio War has 20K ratings behind it against 1.7K, so its average is the more settled of the two. Written reviews point the same way: 69% of Zombie Outbreak Simulator's written reviews are positive against 83% of Infection Bio War's.

Zombie Outbreak Simulator ships an update every 3 months, Infection Bio War every 3 weeks. The most recent releases landed on October 29, 2026 and October 30, 2026 respectively.
