Verdict
The clearest difference is review sentiment: Duck Calculator at 100% against 计算管家Pro's 70%. Duck Calculator also leads on price ($0.99 vs $4.99). 计算管家Pro's advantage is update cadence (every 5 days vs every 7 months) and iOS requirement (10.0 vs 16.0). On ads, in-app purchases, monetization model and device support there is nothing between them.
