Sleep score
This score assesses sleep quality based on data such as total sleep, heart rate variability (HRV), nighttime movement, and sleep regularity.
Sleep stages
Wake up every morning with accurate data on how long you spent in deep sleep, REM sleep, and light sleep the night before.
Blood oxygen measurement
detects blood oxygen levels overnight and can tell you if you are experiencing breathing difficulties.
Sleep score
This score assesses sleep quality based on data such as total sleep, heart rate variability (HRV), nighttime movement, and sleep regularity.
Automatic activity detection
Cycling, basketball, housework, and more than forty other activities. Oura automatically detects them using your heart rate and takes them into account when calculating your scores.
Activity score
Oura analyzes your activity levels, long-term consistency, and recovery time to determine if you are counteracting movement with sufficient rest.
Personalized activity goals
Oura assigns you a personalized daily activity goal based on your recovery. Depending on your priorities, the goal can focus on daily activity or calorie burning.
Readiness Score
Your Readiness Score uses your temperature trends, heart rate, sleep, and more to highlight how energized you are for the day.
Disease detection
Oura detects your temperature and heart rate changes so you know when you might be getting sick.
Daytime stress
Figure out what stresses you out and what contributes to your recovery. By seeing how daily movement, activities, and social labels affect your stress levels, you can find ways to recover more quickly.
Resilience
Monitor how your body recovers from daily physiological stress and learn to gradually improve your resilience.
Cumulative stress
Discover the hidden impact of chronic stress on your body, which accumulates when you don't recover properly from daily stress. This analysis of your cumulative stress helps you prioritize balance and avoid burnout.
Continuous heart rate monitoring
Observe how your heart rate changes, both day and night, and how your body responds to daily habits, meals, stress, and the environment.
Cardiovascular age
Discover at a glance how quickly your cardiovascular system ages in relation to your chronological age and the possible effects that this may have on your long-term health.
Cardiovascular capacity
Calculate your approximate VO2 max to find out if your body transports and uses oxygen efficiently when you do intense physical exertion.
Heart rate variability
Oura tracks HRV to find out if you are stressed, unwell, or need to take a break to recover.
Cycle analysis
Oura uses temperature trends to provide you with more accurate analysis of your menstrual cycle, helping you understand what your body needs throughout the month.
Menstrual predictor
Thanks to its precise measurements, Oura helps you know when your period is coming. Furthermore, by detecting drops in your body temperature, it can help you better manage your cycles.
Integration with Natural Cycles
Oura integrates with Natural Cycles, the first FDA-authorized contraceptive app, allowing temperature data from both apps to be automatically synchronized.
Partner Integrations
You can integrate your Oura data with your trusted birth control and contraceptive apps (Flo, Clue, etc.).
