Verdict

The call

The clearest difference is update cadence: Electrical Engineering at every 2 weeks against Mechanical Formula's every 4 months. Mechanical Formula's advantage is ratings volume (34 vs 6) and iOS requirement (13.0 vs 17.6). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. Mechanical Formula sells 1 one-off in-app purchase and Electrical Engineering sells 6 in-app purchases, starting at $7.99 per 7 days. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

On the App Store both sit at effectively the same score — 4.7 for Mechanical Formula against 4.8 for Electrical Engineering. That said, the two scores are not equally well evidenced: Mechanical Formula has 34 ratings behind it against 6, so its average is the more settled of the two.

UpkeepUpdate frequency

Mechanical Formula ships an update every 4 months, Electrical Engineering every 2 weeks. The most recent releases landed on October 22, 2026 and October 15, 2026 respectively.
