# Electrical Formulator vs Electrodoc Pro

The clearest difference is review sentiment: Electrodoc Pro at 75% against Electrical Formulator's 16%. Electrodoc Pro also leads on in-app purchases (none vs 1) and ratings volume (62 vs 1). Electrical Formulator's advantage is price (Free vs $4.99) and rating (5.0 vs 4.6). On update cadence, ads and device support there is nothing between them.

Electrical Formulator is free to download; Electrodoc Pro costs $4.99 up front. Electrical Formulator sells 1 one-off in-app purchase. Electrodoc Pro asks for nothing beyond the download.

Electrical Formulator holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Electrodoc Pro has 62 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 75% of Electrodoc Pro'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, Electrodoc Pro every 3 months. Both last shipped on September 26, 2026.
