Verdict
The clearest difference is in-app purchases: 智慧门禁 at none against Quick Formula Calculator's 1. 智慧门禁 also leads on ads (none vs shown) and iOS requirement (10.0 vs 15.6). Quick Formula Calculator's advantage is update cadence (monthly vs every 13 months). On price and device support there is nothing between them.
