Verdict
The clearest difference is review sentiment: W2O at 100% against Biology Knowledge Quiz's 43%. W2O also leads on in-app purchases (none vs 5) and ads (none vs shown). Biology Knowledge Quiz's advantage is update cadence (every 3 weeks vs every 24 months) and ratings volume (161 vs 3). On price, device support and iOS requirement there is nothing between them.
