Verdict
The clearest difference is ads: Bio Inc. at none against Zombie Outbreak Simulator's shown. Bio Inc. also leads on rating (4.4 vs 4.1) and iOS requirement (8.0 vs 12.0). On price, review sentiment, ratings volume and update cadence there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Zombie Outbreak Simulator sells 10 one-off in-app purchases and Bio Inc. sells 9 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
Bio Inc. holds the better App Store score, 4.4 against 4.1. Both are backed by a comparable volume of ratings — 1.7K and 2.4K respectively. Written reviews complicate that: 69% of Zombie Outbreak Simulator's written reviews are positive against 61% of Bio Inc.'s, so the app with the better star average is not the one people write more warmly about.
Both ship on a similar rhythm, roughly every 3 months. Both last shipped on November 6, 2026.
