Verdict
The clearest difference is rating: Structural Formulas Study at 5.0 against Chem AI's 4.4. Structural Formulas Study also leads on in-app purchases (none vs 16) and ads (none vs shown). Chem AI's advantage is ratings volume (822 vs 1) and update cadence (fortnightly vs every 5 weeks). On price and device support there is nothing between them.
