Verdict
The clearest difference is ads: SimpleCalc. at none against Calc Pro's shown. SimpleCalc. also leads on device support (4 vs 2) and iOS requirement (15.0 vs 18.0). Calc Pro's advantage is update cadence (monthly vs every 7 months). On price and in-app purchases there is nothing between them.
