“Try fasting. Wake up earlier.  Live outside your comfort zone.”

One-size-fits-all recommendations like these ignore one important truth: Everyone is different. What works for one person doesn’t necessarily work for you.

That’s where Oura comes in.

Oura is your personalized health tool—packing sleep insights, heart rate monitoring, activity tracking, illness monitoring, and more into a single tool that gets to know your personal “normal” and provides tailored insights to help you answer key questions about your health.

What is Oura?

The Oura Ring

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

The Oura App

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?”

What Makes Oura Different?

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 wristable 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 250Hz (250x a second) while other wearables downsample to save on battery. 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 – PSG. Read the study.
    • Heart rate variability: 98.4% reliability compared to medical-grade ECG. Read the study.
    • Temperature: Matches performance with research-grade sensors at >99% and measures changes as small as 0.13 °C. Read the study.
    • Oura is always striving to find new ways of validating and testing our technology while contributing to meaningful research. Read More. 

Personalized to You
With each person comes a unique version of “normal.” Rather than base your averages on impersonal population benchmarks — like “Hit 10,000 steps” — Oura gets to know you and provides personalized baselines and insights. Whether your sleep took a hit after a night out, or you’re prioritizing balance in your wellness routine— Oura helps you reach your goals by delivering the best 360°view of your health.

Easy to Use
Getting started with Oura is a simple process, and its small form factor and lack of a tight wrist band ensure your normal routine carries on uninterrupted.

  • Sleep soundly: You shouldn’t have to disrupt your sleep to track it. Without a screen or vibrations, the Oura Ring is one of the most subtle and comfortable ways to accurately monitor your sleep.
  • Keep your routine: Go about your day without having to worry about tightening a strap or packing a charger. The ring has a battery life of 4-7 days, is water-resistant up to 100m, and can withstand a variety of temperatures, ranging from saunas to ice baths.

Use Your Favorite Apps
While Oura enables activity tracking all on its own, it also gives you the power to integrate Apple Health and Google Fit so that you can import workouts from third-party apps like Strava that you already love.

What Does Oura Measure?

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

Each day, you can quickly glance at your overarching scores, which range 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.

Your Oura scores provide unique and personalized insights compared to other tools. Oura emphasizes key health elements:

  • They are connected. Your scores are connected, which delivers a holistic picture of your health rather than siloed stats. For example, rather than set static activity goals like “10,000 steps,” Oura automatically adjusts your Activity Goal each day based on your Readiness Score. If your body needs time to recover, Oura helps you find that balance.
  • They celebrate recovery. While many tools help you achieve milestones, Oura emphasizes the importance of recovery — whether that’s celebrating the impact of taking a rest day on your body or flagging how a late meal delayed your heart rate recovery.
  • They help you monitor for illness. Oura can help you flag when something is off in your data, like an elevated temperature and even recommend Rest Mode when you need it most.
  • They dig deeper. Inside each of your scores are additional tools to help you answer how your lifestyle impacts your sleep, recovery, and activity. For example, your Sleep Score might flag a poor night of sleep, but it also empowers you to see what elements of your sleep are causing that response.
