Verdict
The clearest difference is ads: KuCalc at none against Duodecuple Calc's shown. KuCalc also leads on iOS requirement (11.0 vs 15.8.3). Duodecuple Calc's advantage is update cadence (every 2 weeks vs every 3 months). On price, in-app purchases and device support there is nothing between them.
