# Mechanical Formula vs Material Engineering

The clearest difference is rating: Material Engineering at 5.0 against Mechanical Formula's 4.7. Mechanical Formula's advantage is ratings volume (34 vs 1) and iOS requirement (13.0 vs 17.0). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Mechanical Formula sells 1 one-off in-app purchase and Material Engineering sells 6 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

Material Engineering 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.

Mechanical Formula ships an update every 4 months, Material Engineering every 3 months. The most recent releases landed on September 19, 2026 and July 6, 2026 respectively.
