Verdict
The clearest difference is in-app purchases: Octodecuple Calc at none against Calculator's 1. Octodecuple Calc also leads on update cadence (every 2 weeks vs every 2 months) and iOS requirement (15.8.3 vs 18.0). Calculator's advantage is ads (none vs shown). On price and device support there is nothing between them.
