# Mechanical Dictionary vs Engineering Math Quiz

The clearest difference is rating: Engineering Math Quiz at 5.0 against Mechanical Dictionary's 4.4. Engineering Math Quiz also leads on update cadence (every 3 weeks vs every 9 months) and iOS requirement (12.0 vs 15.6). Mechanical Dictionary's advantage is ratings volume (5 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Mechanical Dictionary sells 5 in-app purchases, starting at $1.99 per 7 days and Engineering Math Quiz sells 7 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

Engineering Math Quiz holds the better App Store score, 5.0 against 4.4. That said, the two scores are not equally well evidenced: Mechanical Dictionary has 5 ratings behind it against 1, so its average is the more settled of the two.

Mechanical Dictionary ships an update every 9 months, Engineering Math Quiz every 3 weeks. The most recent releases landed on June 6, 2026 and September 7, 2026 respectively.
