# Engineering Math Quiz vs Mechanical Formula

The clearest difference is ads: Mechanical Formula at none against Engineering Math Quiz's shown. Mechanical Formula also leads on ratings volume (34 vs 1). Engineering Math Quiz's advantage is update cadence (every 3 weeks vs every 4 months) and rating (5.0 vs 4.7). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Engineering Math Quiz sells 7 in-app purchases, starting at $4.99 per month and Mechanical Formula sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Engineering Math Quiz holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Mechanical Formula has 34 ratings behind it against 1, so its average is the more settled of the two.

Engineering Math Quiz ships an update every 3 weeks, Mechanical Formula every 4 months. The most recent releases landed on September 7, 2026 and September 19, 2026 respectively.
