Verdict
The clearest difference is in-app purchases: KuCalc3 at none against ZZZ MDEditor's 1. KuCalc3 also leads on ads (none vs shown) and update cadence (daily vs every 3 weeks). ZZZ MDEditor's advantage is iOS requirement (13.0 vs 15.0). On price and device support there is nothing between them.
