Apple Watch added hypertension notifications in watchOS 26, a major health feature aimed at detecting high blood pressure in users. Based on a Digitimes report, watchOS 27 may introduce an upgraded version of this feature, currently under review by the FDA. Hypertension affects approximately 1.3 billion adults globally and is a leading modifiable risk factor for heart attack, stroke, and kidney disease.

Apple highlighted the feature's potential to prevent serious health issues by alerting users to elevated blood pressure readings. The new upgrade details remain undisclosed, but it could enhance detection accuracy or expand availability. No changes were announced at WWDC, suggesting the feature may debut alongside new hardware like the Apple Watch Ultra 4 and Apple Watch Series 12.

Historically, Apple extends health features to older models via software updates, so the upgrade will likely reach existing devices running watchOS 27.
