Apple’s hypertension notifications are now available for Apple Watch and iPhone users in Australia, Malaysia, Colombia, Indonesia, South Korea, Brazil, and Turkey, notes MacRumors.
The feature was announced in September 2025. It can alert users if signs of chronic high blood pressure — or hypertension — are detected.
Hypertension is the leading modifiable risk factor for heart attack, stroke, and kidney disease, and impacts approximately 1.3 billion adults globally. It’s frequently undiagnosed because it often has no symptoms, many people do not see a doctor regularly, and even during a clinical visit, it can be easily missed with a single measurement.
Hypertension notifications on Apple Watch use data from the optical heart sensor to analyze how a user’s blood vessels respond to the beats of the heart. The algorithm works passively in the background reviewing data over 30-day periods, and will notify users if it detects consistent signs of hypertension.
