Verdict
The clearest difference is rating: Zilmet Sizing at 5.0 against NTI net's 4.5. Zilmet Sizing also leads on monetization model (free vs free with in-app purchases) and iOS requirement (11.0 vs 13.0). NTI net's advantage is ratings volume (80 vs 1) and review sentiment (20% vs 0%). On price, ads, in-app purchases and device support 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 4.5. That said, the two scores are not equally well evidenced: NTI net has 80 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 0% of Zilmet Sizing's written reviews are positive against 20% of NTI net's, so the app with the better star average is not the one people write more warmly about.
