What is PAI?

What is PAI?

PAI stands for Personal Activity Intelligence. It’s a scientifically-backed metric that turns heart rate data into a single, personal score, showing users how much activity they need to stay healthy. PAI metric can be used in heart rate devices for people to monitor their exercise levels more intuitively at a glance.

How is works?

The metric takes your heart rate during all activity (even activities that don't involve steps) to generate PAI score.

The objective is to maintain a score of 100 PAI throughout a rolling 7 days.

The score is based on each person’s physical data (age, gender, maximum heart rate, resting heart rate, and the body’s response to exercise.). So the activity everyone need to achieve their goal of 100 is unique to them.

Benefits for the users:

Easy metric:

A single, easy-to-understand activity tracking metric.

Long term health benefits:

According to the HUNT Fitness Study*, people who continuously maintain their PAI scores above 100 have lower risk to get hypertension, heart disease, and type 2 diabetes. So as long as they keep the Huami-PAI™ value above 100, they can maintain good health.


A really personalized metric of your physical activity (everyone’s PAI calculation is different).
