Verdict

The call

The clearest difference is rating: Electric Toolkit at 4.8 against Electrical Calculator's 4.6. Electric Toolkit also leads on iOS requirement (15.6 vs 17.6). Electrical Calculator's advantage is update cadence (every 4 months vs every 9 months) and price ($3.99 vs $5.99). On ratings volume, ads, in-app purchases and monetization model there is nothing between them.
