# Electrical Engineering vs Electric Master

The clearest difference is rating: Electrical Engineering at 4.8 against Electric Master's 3.6. Electrical Engineering also leads on iOS requirement (15.5 vs 17.0). Electric Master's advantage is ads (none vs shown) and update cadence (every 2 weeks vs every 2 months). On price, ratings volume, in-app purchases and monetization model there is nothing between them.

Both are free to download. Electrical Engineering sells 7 in-app purchases, starting at $3.99 per month and Electric Master sells 3 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

Electrical Engineering holds the better App Store score, 4.8 against 3.6. Both are backed by a comparable volume of ratings — 12 and 5 respectively.

Electrical Engineering ships an update every 2 months, Electric Master every 2 weeks. The most recent releases landed on October 22, 2026 and October 24, 2026 respectively.
