Sleep
Get the best sleep of your life, and then some. Wake up to in-depth sleep analysis, so you can improve your habits and transform how you feel. Oura provides insights into your sleep staging throughout the night, blood oxygen levels, HRV, and nighttime heart rate.
Activity
Whether you're running a marathon or running errands, Oura tracks your daily activity, steps, calories burned, and workouts while helping you strike a balance between movement and recovery.
Readiness
Know when to push it and when to take it easy with the Oura Readiness Score. It takes into consideration over 30 different body signals — including temperature, heart rate, HRV, and sleep — to tell you how ready you are for the day ahead.
Stress
Oura will help you identify signs of stress and understand how well your body handles it. You'll know when you need to incorporate more self-care practices and how to recover from long term stressors.
Illness detection
Oura monitors shifts in your temperature and heart rate so you can tell when you may be getting sick sooner.
Women's health
Your cycle impacts your mood, sleep, activity and more, every day. Oura helps you understand how your cycle affects your body, so you can make better, informed decisions about your holistic health. Track the changes in your body throughout your cycle and predict your period up to 30 days in advance.
Heart health
From monitoring your daily heart rate and HRV to discovering your Cardiovascular Age and Cardio Capacity, Oura helps you take care of one of key indicators of your overall health — your heart.
IMPORTANT: Size yourself with the Oura Ring Sizing Kit before you buy. Oura Rings are not standard sizing, and finding the right size will result in the best experience possible.
