Oura Ring Generation 3 Sleep Tracking Research-Grade Sensors Activity Tracker

Accuracy above all.
Enhanced with our new state-of-the-art sleep staging algorithm1, Oura accurately tracks the quality of your sleep based on the time spent in each sleep stage (Light, Deep, REM Sleep) and your key vitals.
Sleep, deciphered.
Unlike other wearables, Oura factors in your key vitals like body temperature, heart rate, and HRV to determine your quality of sleep, how much time you spent in each sleep stage, and more.
Perfect your sleep.
Oura learns about your sleep and based on nights when you've had your best sleep, Oura shares personalized guidance on when to start winding down to improve your sleep quality.
Blood oxygen sensing (SpO2).
The Oura Ring measures your blood oxygen levels while you sleep, giving you a more accurate representation of your nightly sleep quality and breathing patterns. By monitoring your blood oxygen, you can discover signs of illness, altitude, or breathing issues.
