# StrucMaster vs Mechanical Engineering Toolkit

The clearest difference is review sentiment: Mechanical Engineering Toolkit at 57% against StrucMaster's 0%. Mechanical Engineering Toolkit also leads on rating (4.8 vs 3.0) and update cadence (weekly vs every 14 months). StrucMaster's advantage is ads (none vs shown) and iOS requirement (8.0 vs 15.0). On price, in-app purchases and device support there is nothing between them.

Both are free to download. StrucMaster sells 1 one-off in-app purchase and Mechanical Engineering Toolkit sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Mechanical Engineering Toolkit holds the better App Store score, 4.8 against 3.0. That said, the two scores are not equally well evidenced: Mechanical Engineering Toolkit has 64 ratings behind it against 3, so its average is the more settled of the two.
