# NEC Mastery vs Electrical Exam Prep

The clearest difference is update cadence: NEC Mastery at every 10 days against Electrical Exam Prep's every 3 months. NEC Mastery also leads on ratings volume (164 vs 1). Electrical Exam Prep's advantage is rating (5.0 vs 4.8) and iOS requirement (13.0 vs 16). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. NEC Mastery sells 4 in-app purchases, starting at $9.99 per month and Electrical Exam Prep sells 2 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

Electrical Exam Prep holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: NEC Mastery has 164 ratings behind it against 1, so its average is the more settled of the two.

NEC Mastery ships an update every 10 days, Electrical Exam Prep every 3 months. The most recent releases landed on September 21, 2026 and June 3, 2026 respectively.
