Sleep the good life.

Every night, your body performs the equivalent of modern health miracles — everything from improving memory to producing cancer killing T cells. And while you sleep, your body is sending a flurry of signals.

When decoded, these signals — heart rate, body temperature and more — communicate your body’s progress as it prepares you for the next day. And night after night, you sleep through it.

Oura interprets these signals so you can wake up to the insights you need to take on the day.

Making smarter health decisions.

You may hear that "healthy" means eight hours of sleep and 10,000 steps a day. But what’s right for you? And how do your habits shape your health?

Oura empowers you to understand and define your health on your terms, based on your data. Oura helps you give your body exactly what it needs each day to reach its full potential.

What your Oura scores reveal.

Oura provides you with personalized Readiness, Sleep, and Activity scores each day based on your baselines.


An overall measure of your recovery. Your Readiness signals your capacity to perform at your mental, emotional, and physical best. Oura monitors body signals to determine how well-rested you are, and whether or not you’re ready for a challenge.

  • Previous Night’s Sleep Quality
  • Sleep Balance
  • Previous Day’s Activity
  • Activity Balance
  • Resting Heart Rate
  • Body Temperature
  • HRV Balance


A personalized measure of your sleep quality, stages, and duration. Oura helps you optimize your bedtime and provides insights to gradually improve your sleep.

  • Total Sleep
  • Sleep Efficiency
  • Restfulness
  • REM Sleep
  • Deep Sleep

  • Daily Activity Goals Met
  • Training Frequency
  • Training Volume
  • Recovery Time
  • Activity Balance
  • Calories Burned

Constantly validating.

What is Oura?

Oura is health technology designed to educate, inform, and help users accomplish their individual goals. We combine advanced sensor technology with a minimal form factor and a mobile app to deliver personalized insights each day in the form of 3 scores: Readiness, Sleep, and Activity.

How does Oura collect data?

The Oura Ring features a group of advanced sensors and components that, together, enable the ring to monitor key body signals. Technology includes, but is not limited to, NTC body temperature sensors, infrared LED sensors, and an accelerometer.

What data does Oura collect?

Oura measures a list of key signals from your body to inform you of your overall health. Some of those key signals include: resting heart rate, body temperature, heart rate variability (HRV), and respiratory rate.

What is Readiness?

Readiness is an overall measure of your recovery. Oura monitors your body’s signals, picks up on daily habits, and informs you of your capacity to perform at your mental, emotional, and physical best.

How does Oura track sleep?

Oura helps you monitor your sleep each night by measuring things like Total Sleep Time, Sleep Efficiency, Sleep Latency (how long it takes to fall asleep), and Resting Heart Rate, to help you get a better idea for how well you’ve recovered. Oura also provides you with a snapshot of each night’s sleep, which includes the time and duration of your sleep stages (REM, Deep, Light, and Awake).

How does Oura help monitor illness?

One of the key indicators of an impending illness is high relative body temperature. Oura tracks your body temperature over time, showing both daily and weekly body temperature trends. If you begin to feel ill, you can double-check with Oura to see if you have a spike in body temperature, or are showing signs of strain in other metrics like respiratory rate, heart rate, and heart rate variability (HRV).

How often do I need to check the app?

Most of our users check their app when they wake up each morning. However, we recommend checking your Oura app throughout the day, as well as use features like Moment and Tags to stay on top of your health.

What is the Oura Ring made of?

The ring is made of durable titanium, with a diamond-like carbon coating, and a non-allergenic, nonmetallic seamless inner molding.

What is the ring’s battery life?

Depending on usage, the ring’s battery can last up to 7 days. The ring is charged using a small dock, and you typically get a full charge in 20 to 80 minutes.

Can I swim or shower with my Oura Ring?

The Oura Ring is water-resistant up to 328 ft. You can swim, shower, bathe, and do just about anything in the water with your ring.
