Oura ring feature highlights


The Oura ring automatically collects and wirelessly synchs your data to the Oura app. The ring automatically measures your physiological signals, with no switches or flashing lights. 


  • Oura's proprietary pulse waveform and pulse amplitude variation detection with infrared PPG sensor
  • Improved body temperature sensor
  • 3D accelerometer 

The signals the Oura ring processes are:

  • Interbeat interval (IBI)
  • Pulse amplitude variation (related to blood pressure variation)
  • ECG level resting heart rate (RHR)
  • Heart rate variability (HRV)
  • Respiratory rate
  • Movements, and timing, duration and intensity of physical activity
  • Body temperature deviation

Note: The Oura ring doesn't track heart rate during exercise.

Ring material

  • Titanium with scratch resistant coating
  • Non-allergenic, non-metallic, seamless inner molding
  • Ultra light-weight: 4-6 grams (lighter than a conventional ring)
