Verdict

The call

The clearest difference is in-app purchases: ProEye ACS at none against ElectroCalc Pro's 1. ProEye ACS also leads on ads (none vs shown) and update cadence (fortnightly vs every 2 months). ElectroCalc Pro's advantage is iOS requirement (13.0 vs 15.6). On price and device support there is nothing between them.
