Verdict

The call

The clearest difference is ads: 英文小精灵 at none against ElectroCalc Pro's shown. 英文小精灵 also leads on update cadence (every 10 days vs every 3 months). ElectroCalc Pro's advantage is iOS requirement (15.0 vs 17.6). On price, in-app purchases and device support there is nothing between them.
