  • Activity

    Whether you're running a marathon or running errands, Oura tracks your daily activity, steps, calories burned and workouts while helping you strike a balance between movement and recovery.

    From monitoring your daily heart rate and HRV to discovering your Cardiovascular Age and Cardio Capacity, Oura helps you take care of one of the key indicators of your overall health — your heart.

  • Women's Health

    Your cycle impacts your mood, sleep, activity and more, every day. Oura helps you understand how your cycle affects your body, so you can make better, informed decisions about your holistic health. Track the changes in your body throughout your cycle and predict your period up to 30 days in advance.
