Recently, Apple unveiled the high blood pressure alert function for the Apple Watch in numerous countries and regions. This month, this function will be globally launched in over 150 markets through the watchOS 26 and iOS 26 updates. At present, users in the UK, Hong Kong (China), and some other locations are already able to enjoy this function. However, it is not yet accessible in Canada, Mainland China, and certain other regions, with Mainland China still pending regulatory approval. This function made its debut on the Apple Watch Series 11 and Ultra 3 models. Additionally, it is also available to users of Series 9, 10, and Ultra 2. By leveraging optical heart rate sensors, it can detect abnormalities and send reminders to users. Moreover, it has undergone rigorous scientific verification and clinical research.
