How to use PAI ?

PAI is a personalized index that is dynamically calculated based on personal physiological data such as age, gender, and resting heart rate, combined with the individual's own heart rate changes over the past seven days.

1) Wear the strap daily. The strap will automatically record your heart rate data for calculation. Any activity that raises your heart rate will earn you PAI points;

2) You can view the PAI value on the PAI card on the Zepp home page to obtain information.
