A New Vitals App
One of the biggest new additions to watchOS 11 is the introduction of a brand-new app called Vitals.
As you can expect by the name, this new app checks all your most important vitals and provides a better insight into how your body reacts over time.
To be more precise, the Vitals app checks things like your heart rate, wrist temperature, and respiratory rate while you’re sleeping. Then, it gives you a summary of all your vitals the next day. The app keeps your data for weeks or months and then alerts you if it thinks your vitals are off.
This is a helpful way to understand your most important vitals when you sleep. It can also help you understand how your vitals change when you’re sick or if you went out for a few drinks the night before.
