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.

The Vitals app. Your daily health status, stat.

Quickly see your overnight health data — including heart rate, respiratory rate, wrist temperature, and sleep duration — and get notified if multiple metrics are ever outside your typical range.

Follow your heart on the ECG app.

With Series 11 you can check for signs of atrial fibrillation, or AFib, right from your wrist by using the ECG app to generate a single-lead electrocardiogram.

Stay on the pulse with the Heart Rate app.

You can check your heart rate at any time — and get automatic notifications for a high or low heart rate or an irregular rhythm.

Cycle Tracking keeps you in the loop.

Since cycles vary, the best way to understand what’s normal for you is by tracking your menstrual cycle. You can use Cycle Tracking to log your period, record symptoms, and get predictions about your next period or fertile window.¹⁴ It can also notify you if a cycle deviation is detected.

Get retrospective ovulation estimates.

Series 11 has advanced sensors that track your wrist temperature while you sleep. The Cycle Tracking app uses this data to provide a retrospective estimate of when you likely ovulated, which can be helpful for family planning.

Measure your blood oxygen. It’s a breathtaking innovation.

The Health app on iPhone uses data from the sensor in Apple Watch to enable you to take on-demand readings of your blood oxygen as well as background readings, day and night.

All in on 5G.

With 5G, you can download apps, music, and podcasts faster than ever. And thanks to a new 5G modem and antenna architecture, Series 11 provides better coverage in areas with weak reception. Dropped calls? Not on our watch.

It’s all in the wrist flick.

Mute incoming calls, silence timers, dismiss notifications, and more — just by quickly turning your wrist over and back. It’s singlehandedly more convenient when your hands are full.
