# Structural Engineering lite vs CSiMaterials

The clearest difference is in-app purchases: CSiMaterials at none against Structural Engineering lite's 1. CSiMaterials also leads on ads (none vs shown) and iOS requirement (9.0 vs 17.6). Structural Engineering lite's advantage is ratings volume (19 vs 1) and rating (4.2 vs 4.0). On price and device support there is nothing between them.

Both are free to download. Structural Engineering lite sells 1 one-off in-app purchase. CSiMaterials asks for nothing beyond the download.

Structural Engineering lite holds the better App Store score, 4.2 against 4.0. That said, the two scores are not equally well evidenced: Structural Engineering lite has 19 ratings behind it against 1, so its average is the more settled of the two.
