# iEngineer vs Electrician Handbook

The clearest difference is update cadence: Electrician Handbook at every 2 weeks against iEngineer's every 5 months. Electrician Handbook also leads on monetization model (free vs free with in-app purchases) and rating (4.8 vs 4.6). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. iEngineer sells 1 one-off in-app purchase and Electrician Handbook sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Electrician Handbook holds the better App Store score, 4.8 against 4.6. That said, the two scores are not equally well evidenced: Electrician Handbook has 1K ratings behind it against 199, so its average is the more settled of the two. Written reviews complicate that: 86% of iEngineer's written reviews are positive against 79% of Electrician Handbook's, so the app with the better star average is not the one people write more warmly about.

iEngineer ships an update every 5 months, Electrician Handbook every 2 weeks. The most recent releases landed on October 26, 2026 and October 25, 2026 respectively.
