Sleek, comfortable, accurate. Oura Ring fits seamlessly into your life, all night and all day.
Sleep, Readiness, and Activity. Your scores tell you how your body feels and what your body needs, every second of every day. You’ll know when you need more sleep, when you might be getting sick, when it’s time to push yourself — and more — with a personalized experience on the Oura App.
Better health, brighter moods, more energy — it all starts with sleep. Wake up to in-depth analysis about your deep sleep, light sleep, REM sleep, blood oxygen levels, and more. Small adjustments to your daily routine can improve your sleep and transform how you feel.

The Readiness Score provides a holistic picture of your health using over 20 biometric signals. Oura senses if you’re feeling refreshed or stressed, and tells you if today is a day to push yourself or take it easy. With our research-grade temperature sensors, it can even tell you when you might be getting sick — sometimes even before you know it.

Whether you’re running a marathon or running an errand, Oura tracks your movement, steps, heart rate, and recovery. Discover your ideal balance between activity and recovery to reach your personal fitness goals.
The Oura Ring is designed for accuracy above all because it measures from the palm side of your finger, where the pulse signal is strong to read from —much stronger than the wrist (Doctors measure your heart rate from your finger for a reason).
