Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
Simple Subnet Calc holds the better App Store score, 5.0 against 4.0.

Written reviews complicate that: 61% of Simple Subnet Calc's written reviews are positive against 78% of HE.NET Network Tools's, so the app with the better star average is not the one people write more warmly about.
