# Sizing US/CA vs Zilmet Sizing

The clearest difference is rating: Zilmet Sizing at 5.0 against Sizing US/CA's 3.2. Zilmet Sizing also leads on ads (none vs shown) and monetization model (free vs ad-supported). Sizing US/CA's advantage is ratings volume (13 vs 1) and review sentiment (11% vs 0%). On price, in-app purchases, device support and iOS requirement there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Zilmet Sizing holds the better App Store score, 5.0 against 3.2. That said, the two scores are not equally well evidenced: Sizing US/CA has 13 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 11% of Sizing US/CA's written reviews are positive against 0% of Zilmet Sizing's, so the app with the better star average is not the one people write more warmly about.
