Overview
- Apple activated the feature in Canada with concurrent rollouts in Singapore and Bahrain, with setup available in the iPhone Health app.
- Supported devices include Apple Watch Series 9–11 and Ultra 2–3 on watchOS 26, excluding all SE models, with eligibility limited to users 22 or older who are not pregnant and not previously diagnosed with hypertension.
- The tool does not measure blood pressure or display readings, requires no calibration, and functions as a screening aid rather than a diagnostic device.
- If an alert appears, the Health app guides users to log seven days of measurements using a standard cuff and to share results with a clinician.
- Apple cites training data from studies totaling over 100,000 participants and validation in a clinical study of 2,000+ people, following FDA clearance and Health Canada licensing ahead of this expansion.
