Why PAI?
A simple way to measure what matters
PAI measures the heart health impact of your physical activity and guides you to a longer, healthier life.
What is PAI?
PAI (Personal Activity Intelligence) is a science-backed health score that measures the heart health impact of physical activity.
It gives you a personalized score, based on your profile and heart rate data to tell you if you’re doing enough, measuring what matters and keeping you motivated.
Personal profile
PAI works with popular wearable devices to customize to your profile factoring in sex, age, and resting/maximum heart rate.
PAI Score
The proprietary algorithm calculates a PAI Score using personal profile data and heart rate data on a rolling 7-day basis.
Results
Maintaining a weekly PAI Score of 100 or more is associated with an average 25% risk reduction in cardiovascular disease mortality.

A smarter way to track your activity
Start understanding the impact of everything you do on your heart, not just exercise and steps.
The benefits of using PAI
Simple
Makes sense of heart rate data and translates it into one meaningful number to focus on.
Universal
Recognizes all activity that gets your heart pumping and body moving, and works for all fitness levels.
Scientific
A validated prescription for physical activity to optimize your cardiovascular health.
Personal
Tailored to you and adapts as you progress.
"The beauty of the PAI measurement is that it is cumulative, incorporating the last few days' exercise, whether low or high intensity. As long as you remain above 100 PAI, you have achieved your health goal for the week."
Science and research
PAI is backed by science. Research has found that maintaining 100 PAI or more is strongly associated with adding up to 5 years in lifespan and reducing the risk of cardiovascular disease mortality by an average of 25%.
As a physician and practicing cardiologist, I’ve never seen a metric as personal and quantifiable to the protection of lifestyle-related diseases as PAI. It's better than any general exercise guideline that physicians have been able to give to their patients, and I believe PAI is the potential game changer for raising physical activity to improve global health.”
