# iMask vs Nutrisense

The clearest difference is rating: Nutrisense at 4.3 against iMask's 1.3. Nutrisense also leads on update cadence (weekly vs every 4 months) and review sentiment (27% vs 2%). iMask's advantage is monetization model (free vs free with in-app purchases) and iOS requirement (12.0 vs 15.5). 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.

Nutrisense holds the better App Store score, 4.3 against 1.3. That said, the two scores are not equally well evidenced: Nutrisense has 4.3K ratings behind it against 63, so its average is the more settled of the two. Written reviews point the same way: 2% of iMask's written reviews are positive against 27% of Nutrisense's.

iMask ships an update every 4 months, Nutrisense weekly. The most recent releases landed on October 7, 2026 and October 14, 2026 respectively.
