Verdict

The call

The clearest difference is price: Electrical Engineering at Free against Electrodoc Pro's $4.99. Electrical Engineering also leads on rating (4.9 vs 4.6). Electrodoc Pro's advantage is in-app purchases (none vs 8) and ads (none vs shown). On review sentiment, update cadence and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Electrical Engineering holds the better App Store score, 4.9 against 4.6. That said, the two scores are not equally well evidenced: Electrodoc Pro has 62 ratings behind it against 11, so its average is the more settled of the two. Written reviews complicate that: 75% of Electrodoc Pro's written reviews are positive against 74% of Electrical Engineering's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Electrodoc Pro ships an update every 3 months, Electrical Engineering every 2 months. The most recent releases landed on September 26, 2026 and September 28, 2026 respectively.
