# NutriScale AI vs AVIX

The clearest difference is rating: NutriScale AI at 4.8 against AVIX's 4.3. NutriScale AI also leads on iOS requirement (15.0 vs 17.0). AVIX's advantage is review sentiment (58% vs 30%). On price, ratings volume, update cadence and ads there is nothing between them.

Both are free to download. NutriScale AI sells 4 in-app purchases, starting at $2.99 per 7 days and AVIX sells 13 in-app purchases, starting at $6.99 per month. Whichever you choose, the download price is not the number that matters.

NutriScale AI holds the better App Store score, 4.8 against 4.3. Both are backed by a comparable volume of ratings — 388 and 272 respectively. Written reviews complicate that: 30% of NutriScale AI's written reviews are positive against 58% of AVIX's, so the app with the better star average is not the one people write more warmly about.

NutriScale AI ships an update every 8 days, AVIX every 11 days. The most recent releases landed on October 25, 2026 and October 22, 2026 respectively.
