Oura Ring

Oura Ring makes Heart Rate & Blood Oxygen Sensing effortless.

Starting at $299 + $5.99/mo for membership*

  • A smart ring to monitor your heart rate and overnight SpO2 — from the comfort of your home.
  • Used for daytime and nighttime heart rate monitoring.
  • Long battery life of up to 7 days.
  • Easily share your heart rate and activity insights with your physician, trainer, caregiver, or family member.

* First month of membership is on us with your purchase. $5.99/mo afterwards.


  • You can track your heart health with daytime and nighttime heart rate tracking, workout heart rate tracking, nighttime heart rate variability (HRV) tracking, and activity level monitoring (steps and calories).

  • By detecting your blood oxygen levels at night, Oura can tell if you're experiencing any breathing disturbances that may interrupt your sleep.

  • Accuracy Above All

    The Oura Ring is designed for accuracy above all because it measures from the palm side of your finger, where the pulse signal is strong — much stronger than the top of your wrist (doctors measure your heart rate from your finger for a reason).

  • Measure Your HRV

    Your Sleep Score is made up of seven Sleep Contributors including sleep stages (deep sleep, light sleep, REM), timing, and efficiency.

  • Health Stats

    Oura Ring records heart health stats, including heart rate and HRV, as well as overnight blood oxygen and breathing rate.

  • Lightweight Titanium

    Durable and lightweight titanium ring design for comfort and accuracy. Hypoallergenic, non-metallic, seamless inner molding. Water resistant up to 100m/328 ft.

  • Trends

    Oura Ring provides key health metrics and trends in graphs and reports via the Oura App to help you understand how to track and improve your health metrics. You can download your data to share with your physician, trainer, caregiver, or family member.

The Oura Ring has been used in independent studies at UCSF, UC San Diego, MIT Lincoln Laboratory, the US Army, and the US Navy — with more already in the works.

UC San Diego

University of California, San Diego is using Oura Ring to look for patterns in heart rate and heart rate variability (HRV), combined with other vitals that may help identify the onset of pregnancy and/or help predict different pregnancy outcomes and progressions.

West Virginia University

A team of researchers at West Virginia University published a new study on the accuracy of consumer tools at measuring heart rate and HRV. The infrared photoplethysmogram (PPG) sensor in the Oura Ring nearly matched performance with clinical-grade ECG and consistently outperformed other PPG tools.
