Hypertension, or high blood pressure, impacts over 1.3 billion adults worldwide and is a leading cause of a heart attack, stroke, and kidney disease. The condition frequently goes undiagnosed because it often has no symptoms — and even during a doctor’s visit, with a single measurement it can be easily missed.

Receive hypertension notifications just by wearing your watch.

Series 11 can notify you if it identifies patterns of hypertension.¹ How? The optical sensor provides data to an algorithm that can detect potential hypertension by analyzing how your blood vessels respond to beats of the heart over 30-day periods.

Groundbreaking insights. Grounded in science.

We developed hypertension notifications using advanced machine learning methods and a series of studies totaling over 100,000 participants. The feature was then validated in a clinical study.

Set up a blood pressure log.

If you receive a hypertension notification and have access to a blood pressure cuff, you can track your blood pressure in the Health app on iPhone to create a report that will lead to more meaningful conversations with your healthcare provider.

Wake up to your sleep score.

Sleep quality is influenced by factors such as sleep duration, bedtime consistency, how often you wake up, and time spent in each sleep stage. Sleep score analyzes these factors every night and provides a classification and a score. You’ll see how the score is calculated, so you can understand the quality of your sleep and learn how to make it more restorative.

Keep an eye on sleep apnea.

Sleep apnea is a condition where people experience repeated interruptions in their regular respiratory pattern during sleep. If untreated, it can lead to increased risk of hypertension, type 2 diabetes, cardiac issues, and more. Series 11 can monitor for breathing disturbances over time and notify you of possible sleep apnea.¹¹

Better by every measure.
