How to correctly wear your FITTR HART Ring For best performance and accurate readings, we recommend wearing your HART Ring on the index finger of your non-dominant hand. Middle and ring fingers work too, if that’s what you prefer. Just make sure that the ring fits securely and comfortably around the base of your finger - not too loose, not too tight. Note: the ring’s sensor should face the palm side of your finger and not the top. How to use the FITTR ONE app After activating the ring, please pair with the FITTR ONE app to start using.

Verdict
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.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
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.
