Verdict
The clearest difference is in-app purchases: DSE 數學公式 at none against HKDSE Chemistry's 1. DSE 數學公式 also leads on ads (none vs shown). HKDSE Chemistry's advantage is update cadence (every 3 weeks vs every 3 months) and iOS requirement (11.0 vs 15.0). On price, rating, review sentiment and ratings volume there is nothing between them.
