Verdict
The clearest difference is rating: Electrical Formulator at 5.0 against Electric circuit calculator's 4.2. Electrical Formulator also leads on update cadence (every 2 months vs every 4 months). Electric circuit calculator's advantage is review sentiment (33% vs 16%) and ratings volume (10 vs 1). 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. Electrical Formulator sells 1 one-off in-app purchase and Electric circuit calculator sells 3 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.
Electrical Formulator holds the better App Store score, 5.0 against 4.2. That said, the two scores are not equally well evidenced: Electric circuit calculator has 10 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 16% of Electrical Formulator's written reviews are positive against 33% of Electric circuit calculator's, so the app with the better star average is not the one people write more warmly about.
Electrical Formulator ships an update every 2 months, Electric circuit calculator every 4 months. The most recent releases landed on September 26, 2026 and September 23, 2026 respectively.
