How do I use PAI?

PAI is a personal indicator that is dynamically calculated based on each individual's age, gender, resting heart rate, and other personal physiological data in combination with the person's heart rate changes over the past 7 days.
1) Open the Zepp app, go to Profile > Amazfit Cheetah (Square) > Health Monitoring, and enable All-Day Heart Rate. It is recommended to also enable Activity Detection to record more heart rate changes to increase calculation accuracy.
2) Wear the watch every day, and the watch will automatically record your heart rate data for calculation. Activities that can improves the heart rate will help you earn more PAI points.
3) Go to the PAI app in the watch or PAI Card in the Zepp app to view the PAI points.
