# Electrical Engineering vs Simurelay

The clearest difference is rating: Electrical Engineering at 4.7 against Simurelay's 3.9. Electrical Engineering also leads on ratings volume (252 vs 17). Simurelay's advantage is ads (none vs shown) and review sentiment (52% vs 33%). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. Electrical Engineering sells 2 one-off in-app purchases and Simurelay sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Electrical Engineering holds the better App Store score, 4.7 against 3.9. 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 complicate that: 33% of Electrical Engineering's written reviews are positive against 52% of Simurelay's, so the app with the better star average is not the one people write more warmly about.

Electrical Engineering ships an update every 4 months, Simurelay every 7 months. The most recent releases landed on September 22, 2026 and August 1, 2026 respectively.
