Verdict
The clearest difference is in-app purchases: Germs Survivor at none against Bit City's 5. Germs Survivor also leads on update cadence (every 2 days vs every 2 months) and review sentiment (100% vs 79%). Bit City's advantage is ratings volume (8.5K vs 4) and rating (4.6 vs 4.3). On price, ads and device support there is nothing between them.

Both are free to download. Bit City sells 5 one-off in-app purchases. Germs Survivor asks for nothing beyond the download.
Bit City holds the better App Store score, 4.6 against 4.3. That said, the two scores are not equally well evidenced: Bit City has 8.5K ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 79% of Bit City's written reviews are positive against 100% of Germs Survivor's, so the app with the better star average is not the one people write more warmly about.
Bit City ships an update every 2 months, Germs Survivor every 2 days. The most recent releases landed on October 25, 2026 and October 24, 2026 respectively.
