# Mechanical Dictionary vs Material Engineering

The clearest difference is rating: Material Engineering at 5.0 against Mechanical Dictionary's 4.4. Material Engineering also leads on ads (none vs shown) and update cadence (every 3 months vs every 9 months). Mechanical Dictionary's advantage is ratings volume (5 vs 1) and iOS requirement (15.6 vs 17.0). On price, in-app purchases, monetization model and device support 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 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 4.4. 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, Material Engineering every 3 months. The most recent releases landed on September 16, 2026 and October 1, 2026 respectively.
