# Electrical Formulator vs Electrical Calculations

The clearest difference is review sentiment: Electrical Calculations at 87% against Electrical Formulator's 16%. Electrical Calculations also leads on ratings volume (126 vs 1) and update cadence (every 3 weeks vs every 2 months). Electrical Formulator's advantage is ads (none vs shown) and rating (5.0 vs 4.6). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Electrical Formulator sells 1 one-off in-app purchase and Electrical Calculations sells 3 in-app purchases, starting at $3.99 per 3 months. Whichever you choose, the download price is not the number that matters.

Electrical Formulator holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Electrical Calculations has 126 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 87% of Electrical Calculations'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, Electrical Calculations every 3 weeks. The most recent releases landed on September 3, 2026 and September 22, 2026 respectively.
