# Electrical Formulator vs Electrical Engineering

Electrical Formulator and Electrical Engineering both sit at 5.0 stars, but that hides the real split: 74% of Electrical Engineering's written reviews are positive against 16% of Electrical Formulator's. Electrical Engineering also leads on ratings volume (11 vs 1) and iOS requirement (15.5 vs 18.4). Electrical Formulator's advantage is ads (none vs shown). On price, rating, update cadence and in-app purchases there is nothing between them.

Both are free to download. Electrical Formulator sells 1 one-off in-app purchase and Electrical Engineering sells 7 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 5.0 for Electrical Formulator against 4.9 for Electrical Engineering. That said, the two scores are not equally well evidenced: Electrical Engineering has 11 ratings behind it against 1, so its average is the more settled of the two. Written reviews are what separate them: 16% of Electrical Formulator's written reviews are positive against 74% of Electrical Engineering's.

Both ship on a similar rhythm, roughly every 2 months. The most recent releases landed on September 3, 2026 and September 22, 2026 respectively.
