Verdict
The clearest difference is rating: Bacterias at 3.8 against Germs!'s 1.0. Bacterias also leads on review sentiment (40% vs 0%) and update cadence (every 3 months vs every 34 months). Germs!'s advantage is ads (none vs shown) and monetization model (free vs free with in-app purchases). On price, in-app purchases and device support there is nothing between them.
