Verdict
The clearest difference is in-app purchases: HTMercury at none against ElectroCalc Pro's 1. HTMercury also leads on ads (none vs shown) and iOS requirement (8.0 vs 13.0). ElectroCalc Pro's advantage is update cadence (every 2 months vs every 9 months). On price and device support there is nothing between them.
