Frequently asked questions
Are smart rings actually accurate?
Premium models like the Oura Ring and Samsung Galaxy Ring have clinically validated accuracy for heart rate and sleep. HRV is more variable but statistically reliable as a trend. They're not medical devices but they are serious health tools.
How long until the data becomes useful?
The first 2 weeks are calibration. From the third week onward the data is personalized and trends start to be actionable. The most noticeable habit changes typically emerge between 4 and 8 weeks of use.
Can you wear it on any finger?
Technically yes, but for best accuracy the index, middle or ring finger of your non-dominant hand is recommended. The pinky gives less precise readings.
What about wearing it alongside a wedding ring?
No interference. The smart ring goes on a different finger or on the other hand. Many users wear their wedding band on the left hand and the smart ring on the right index finger.
Is the data private?
Oura and Samsung encrypt data and do not sell it to third parties. You can review and delete your data at any time from the app. Oura allows full CSV data export.
Where to buy with warranty?
Oura Ring: ouraring.com with direct shipping and official warranty. Samsung Galaxy Ring: samsung.com/us, Best Buy and Amazon. Ultrahuman: ultrahuman.com with shipping to the US in 3-5 business days.
