# NutriSync vs GentleGut

NutriSync and GentleGut both sit at 4.8 stars, but that hides the real split: 100% of GentleGut's written reviews are positive against 89% of NutriSync's. GentleGut also leads on iOS requirement (15.0.0 vs 17.0). On price, rating, ratings volume and update cadence there is nothing between them.

Both are free to download. NutriSync sells 14 in-app purchases, starting at $3.99 per month and GentleGut sells 4 in-app purchases, starting at $6.99 per month. Whichever you choose, the download price is not the number that matters.

NutriSync holds the better App Store score, 4.8 against 4.6. Both are backed by a comparable volume of ratings — 69 and 29 respectively. Written reviews complicate that: 89% of NutriSync's written reviews are positive against 100% of GentleGut's, so the app with the better star average is not the one people write more warmly about.

NutriSync ships an update weekly, GentleGut every 9 days. Both last shipped on October 28, 2026.
