# FITTR ONE vs 9FIT SmartRing

The clearest difference is rating: 9FIT SmartRing at 5.0 against FITTR ONE's 3.8. 9FIT SmartRing also leads on iOS requirement (13.0 vs 16.2). FITTR ONE's advantage is ratings volume (13 vs 2). On price, review sentiment, update cadence and ads there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

9FIT SmartRing holds the better App Store score, 5.0 against 3.8. That said, the two scores are not equally well evidenced: FITTR ONE has 13 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 74% of FITTR ONE's written reviews are positive against 69% of 9FIT SmartRing's, so the app with the better star average is not the one people write more warmly about.

FITTR ONE ships an update every 10 days, 9FIT SmartRing fortnightly. Both last shipped on November 4, 2026.
