Sleep Score
Sleep Score classifies a night using factors including sleep duration, bedtime consistency, and interruptions. It is a way to review sleep patterns, not a medical diagnosis.
Hypertension notifications
On supported models and in available regions, watchOS 26 can notify eligible users when the watch detects persistent signs associated with chronic high blood pressure. Apple Support says detection looks for consistent signs across a 30-day period; that is a feature threshold, not a population statistic.
These notifications are not a diagnosis and do not replace a blood-pressure measurement or medical care. Apple says the feature is intended for people aged 22 or older who have not been diagnosed with hypertension and are not pregnant. Model and regional restrictions apply.
Workout Buddy
Workout Buddy uses Apple Intelligence to provide personalized spoken encouragement and workout insights. Apple says it requires Bluetooth headphones connected to Apple Watch and a nearby iPhone that supports Apple Intelligence. Language availability also applies.
