Verdict

The call

The clearest difference is monetization model: Science Practical Simulator at free with in-app purchases against Chem AI's subscription. Science Practical Simulator also leads on ads (none vs shown) and iOS requirement (12.0 vs 16.0). Chem AI's advantage is update cadence (fortnightly vs every 6 months) and review sentiment (20% vs 8%). On price, in-app purchases and device support there is nothing between them.
