Verdict

The call

The clearest difference is in-app purchases: 簡易計算機 at none against Unit Converter's 1. 簡易計算機 also leads on iOS requirement (8.0 vs 12.0). Unit Converter's advantage is update cadence (every 2 weeks vs every 45 months). On price, ads and device support there is nothing between them.
