Last week Apple shipped the first iOS 26.2 and watchOS 26.2 betas with a big change to Sleep Score’s grading system. After nearly a week with the new Sleep Score, here’s how I’m feeling about the updates.
Sleep Score refinements in iOS 26.2 and watchOS 26.2
Sleep Score is one of two major Health features that debuted in iOS and watchOS 26.
