# Electrical Engineering vs Arduino Pocket Reference

The clearest difference is rating: Electrical Engineering at 4.7 against Arduino Pocket Reference's 2.4. Electrical Engineering also leads on review sentiment (33% vs 12%) and ratings volume (252 vs 17). Arduino Pocket Reference's advantage is iOS requirement (14.0 vs 17.6). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Electrical Engineering sells 2 one-off in-app purchases and Arduino Pocket Reference sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Electrical Engineering holds the better App Store score, 4.7 against 2.4. That said, the two scores are not equally well evidenced: Electrical Engineering has 252 ratings behind it against 17, so its average is the more settled of the two. Written reviews point the same way: 33% of Electrical Engineering's written reviews are positive against 12% of Arduino Pocket Reference's.

Electrical Engineering ships an update every 4 months, Arduino Pocket Reference every 5 months. The most recent releases landed on September 22, 2026 and June 2, 2026 respectively.
