Health Features

Understand your Night

While you sleep, essential data is collected. The ring tracks sleep stages, duration, and consistency, turning them into a clear sleep score. Overnight, it also monitors heart metrics, body temperature, and blood oxygen — revealing how well you recover and how ready you are for the day ahead.

Stay active every day

The ring tracks your daily movement — including steps, distance, active calories, and training load — and turns it into a dynamic activity score that updates throughout the day. You can set personalized goals and choose from 200+ workout types, each with detailed performance analytics, helping you balance activity, progress, and recovery effortlessly.

Mind Balance

By tracking changes in your temperature, heart rate variability, and sleep, the ring provides insights into your stress levels throughout the day, helping you understand your body and better manage challenging moments.

Your heart in Your hands

The ring continuously tracks your heart rate, heart rate variability (HRV), and blood oxygen, providing a full picture of how your body responds to daily activity, stress, and recovery.

Ring detects decreases in your body temperature caused by shifting hormone levels to accurately predict when you’ll start your period.

Frequently asked questions

The sensors in the Magno Ring have been tested against laboratory results in multiple validation studies. Learn more about Science & Research at Magno.
Wearables differ in where they're worn, the sensors they use, and how they process data. For the most consistent and meaningful insights, it's best to track trends and changes over time within your Oura Ring and Oura App, rather than comparing your Oura results to those from other devices.

Magno Ring is water-resistant up to 100 meters (~330 feet), meaning that you can wear it while showering, swimming, or partaking in recreational diving (e.g. snorkeling), but we don’t recommend using your Magno Ring while scuba diving or keeping it submerged underwater for over 12 hours. Chlorine will not damage it.
Magno Ring operating temperature ranges from -10–52°C / 14–125°F. You can safely wear your Magno Ring in the shower, hot tubs, saunas, ice baths, and cryotherapy tanks. However, extended exposure to extreme temperatures (below -20°C / -4°F or above 60°C / 140°F) may lead to battery damage.
