Verdict
The clearest difference is review sentiment: Elementem at 100% against Chemical Structures Quiz's 50%. Elementem also leads on price ($1.99 vs $3.99). Chemical Structures Quiz's advantage is update cadence (every 2 months vs every 9 months) and iOS requirement (11.0 vs 15.6). On ads, in-app purchases, monetization model and device support there is nothing between them.
