Everything your body is telling you
Your finger carries a strong pulse signal, so the Herz P1 reads 10+ biometrics with less on your wrist and less to charge.
Stress
Master your stress
The ring identifies stress signals and reveals how your body handles them, so you know when to take care of yourself and how well you recover.
Heart
Monitor your heart health
Heart rate and HRV every day, plus blood oxygen. Regular readings show how your heart responds to training, sleep and stress over time.
Activity and goals
Track your activity, hit your goals
Customize your daily goals and watch your progress over time. Training for an event or just moving more, find the balance between movement and recovery.
Women's health
Understand your cycle
See how your cycle affects your mood, sleep and activity, so you can make informed decisions about your health.
Built to disappear on your finger
Light enough to sleep in, tough enough for the pool, and quiet until you want your data.
Engineered for accuracy
Optical heart rate sensors and an accelerometer read your pulse where it is strongest, for reliable insights across 10+ biometrics.
Comfort you can wear anywhere
Stylish and comfortable, from a busy day to an elegant night out. You'll forget it's there.
