## What is HRV Stress Tracker?

Make sense of your heart rate variability with NoStress. View an estimated stress level based on HRV alongside the health readings available from your connected sources.

• HRV, heart rate and resting heart rate.
• Sleep duration, blood oxygen, respiratory rate and steps when your source supplies them.
• A daily overview and historical charts to compare changes over time.
• Apple Health and optional Google Health sync for supported data.
• Apple Watch views and widgets for a quick glance.

NoStress reads recorded health data; it does not measure HRV with the phone camera. A compatible wearable or another source of HRV data is needed for stress estimates. Metric availability and update frequency depend on the source and the permissions you grant.

For general wellbeing and information only. Stress estimates are not a diagnosis, medical advice or a treatment recommendation.
