# Engineering Physics Quiz vs Mechanical Formula

The clearest difference is ads: Mechanical Formula at none against Engineering Physics Quiz's shown. Engineering Physics Quiz's advantage is update cadence (every 3 weeks vs every 4 months). On price, in-app purchases, device support and iOS requirement there is nothing between them.

Both are free to download. Engineering Physics 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 Physics Quiz ships an update every 3 weeks, Mechanical Formula every 4 months. The most recent releases landed on March 3, 2026 and September 19, 2026 respectively.
