A major new health feature for recent Apple Watch models can alert users to possible hypertension (aka high blood pressure) by analyzing patterns in their heart data over time. Apple offered a document earlier this week explaining how the Hypertension Notifications feature works using existing sensors.
Available with watchOS 26, the feature works on Apple Watch Series 9 and later models, as well as the Apple Watch Ultra 2 and later.
