Why and how
A deliberate moment, under more consistent conditions.
Apple Watch measures heart rate throughout the day, often while you are moving, resting, or doing different activities. Heart Baseline gives you a deliberate moment to sit still and capture a short check under more consistent conditions.
That check becomes a simple record you can return to later on iPhone, alongside daily context from Apple Health.
