Track how your heart responds to all activity — not just steps

PAI helps you to measure what matters — the heart health impact of physical activity. It gives you a personalized goal that tells you if you are doing enough and it adapts as you progress.

PAI is backed by science. Maintaining 100 PAI or more is associated with reducing the risk of cardiovascular disease mortality by an average of 25%.
