# Structural Engineering lite vs CSiStress

The clearest difference is rating: Structural Engineering lite at 4.2 against CSiStress's 2.5. Structural Engineering lite also leads on ratings volume (19 vs 2). CSiStress's advantage is in-app purchases (none vs 1) and ads (none vs shown). 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. CSiStress asks for nothing beyond the download.

Structural Engineering lite holds the better App Store score, 4.2 against 2.5. That said, the two scores are not equally well evidenced: Structural Engineering lite has 19 ratings behind it against 2, so its average is the more settled of the two.
