Oura Ring: The Ultimate Wearable for Accurate Sleep, Health, and Activity Insights

Oura Ring

The Oura Ring delivers personalized health insights using advanced sensors for sleep, activity, readiness, and temperature monitoring.

Oura Ring is a ring that uses advanced sensor technology to deliver personalized sleep and health insights straight from the most reliable source: your body.

Through your Oura App, you are empowered to optimize your daily routines and answer key questions about your health like: “How ready am I for the day?”, “How well did I sleep last night?” and “How am I balancing my activity with rest?” Oura is designed to provide accurate insights without disrupting your life. With precise sensors, Oura packs state-of-the-art heart rate, heart rate variability (HRV), temperature, activity, and sleep monitoring technology into a lightweight, non-invasive ring.

Accuracy Above All
When you visit your doctor, there’s a reason they measure your pulse from your finger and not the wrist: accuracy. Your  finger is the ideal source for reliable, impactful data, and Oura leverages this reality by:

  • Measuring closer to your heart: While writable sensors sit far away from the arteries on the underside of the wrist, Oura measures directly from the arteries in your fingers to capture signals directly from your heart.
  • Prioritizing the right sensors: Oura uses infrared light photoplethysmography (PPG), which measures deeper than the green light LEDs found in most other wearables.
  • Taking your temperature: Oura is one of the only wearables that measures your temperature directly from your skin, 24/7. Temperature is one of your core vital signs and reveals key insights about your body’s systems, including impacts of strain, illness, and phases of the menstrual cycle.
  • Maximizing data quality: Oura samples at an unparalleled sampling rate of 50Hz. More data enables richer insights.
  • Constantly validating: While Oura is not a medical device, its capabilities are near perfect when compared to advanced medical technologies.
    • Resting heart rate: 99.9% reliability compared to a medical-grade electrocardiogram (ECG) and validated against the sleep lab golden standard.
    • Heart rate variability: 98.4% reliability compared to medical-grade ECG.
    • Temperature: Matches performance with research-grade sensors at >99% and measures changes as small as 0.13 °C.
    • Oura always strives to find new ways of validating and testing our technology while contributing to meaningful research.

Easy to Use
While Oura enables activity tracking on its own, it also gives you the power to integrate apps such as Apple Health, Google Fit and Strava that you already use and love.

Your body’s signals are wrapped up into three simple scores that help you answer different questions about your health:

  • Your Readiness Score:  “How ready are you for the day?”
  • Your Sleep Score: “How well did you sleep last night?”
  • Your Activity Score: “How well are you balancing your activity and rest?”

Each day, you can quickly glance at your overarching scores ranging from 0-100 to get a daily overview of your health.

Your Readiness Score is your main score and helps you understand your capacity for the day so you know when to push and when to take it easy.
