Verdict
The clearest difference is ads: The Calculo at none against Octuple Calc's shown. The Calculo also leads on iOS requirement (12.0 vs 15.8.3). Octuple Calc's advantage is update cadence (every 2 weeks vs every 2 months). On price, in-app purchases and device support there is nothing between them.
