Verdict
The clearest difference is rating: ElectriCalc Pro at 4.9 against Conduit Fill Pro's 3.7. ElectriCalc Pro also leads on ratings volume (354 vs 3) and iOS requirement (14.0 vs 18.0). Conduit Fill Pro's advantage is review sentiment (100% vs 78%). On price, ads, in-app purchases and monetization model there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. ElectriCalc Pro sells 2 in-app purchases, starting at $4.99 per month and Conduit Fill Pro sells 2 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.
ElectriCalc Pro holds the better App Store score, 4.9 against 3.7. That said, the two scores are not equally well evidenced: ElectriCalc Pro has 354 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 78% of ElectriCalc Pro's written reviews are positive against 100% of Conduit Fill Pro's, so the app with the better star average is not the one people write more warmly about.
