Stress monitor FAQ
How can an app measure stress?
It measures a physiological proxy. When you are stressed, your sympathetic nervous system raises heart rate and reduces heart rate variability. Pulse Tracker reads both from your pulse wave and converts them into a stress level and energy level, calibrated against your own baseline and your age.
What is the Heart Score?
A 0 to 100 summary of your resting heart rate, HRV, stress and energy for the current measurement. High scores mean good balance and recovery; low scores suggest a lighter day and an earlier night.
Can it help with anxiety?
The app includes guided breathing programs for anxiety relief, panic attacks, stress release, sleep and relaxation, and you can measure before and after to see the effect. It is not a treatment for an anxiety disorder; please talk to a professional if anxiety is affecting your life.
