PAI is Personal Activity Intelligence. Rather than just using steps, PAI’s revolutionary algorithm makes sense of your personal heart rate data, giving you a simple number that shows how much activity you need to live a longer, healthier life.

Backed By Science

The PAI system was created from the HUNT study, one of the world’s largest health studies involving more than 45,000 people over 25 years.


Count More Than Steps

PAI analyzes every movement you make, including activities like spinning, yoga, even gardening.


Move With Meaning

PAI tracks your heart rate intensity and shows which activities earned the most PAI points in your day so you can make better lifestyle choices.


One Simple Goal

All you need is one number – your PAI score. Keep it above 100 over a 7-day rolling window to know you’re staying healthy.


Personlized To You

No matter what your fitness level is, PAI shows you what intensity level you need to be in to improve.
