The clearest difference is review sentiment: iGradient at 94% against NTI net's 20%. iGradient also leads on iOS requirement (9.3 vs 13.0). NTI net's advantage is price (Free vs $2.99) and update cadence (monthly vs every 6 months). On ads, in-app purchases and device support there is nothing between them.

NTI net holds the better App Store score, 4.5 against 4.3. That said, the two scores are not equally well evidenced: NTI net has 76 ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 94% of iGradient'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.
