The update adds more useful overnight health context, a way to compare recent workouts with a longer-term baseline, flexible Activity goals, and practical tools such as Check In and Translate on your wrist. watchOS 11 launched on September 16, 2024, and supports Apple Watch Series 6 or later paired with an iPhone XS or later running iOS 18; Apple notes that feature availability varies by device and region.
1. Vitals brings overnight health measures together
The Vitals app summarizes selected overnight measures, including heart rate, respiratory rate, wrist temperature, sleep duration, and blood oxygen where available. It can notify you when two or more measures fall outside your typical range and provide context that may help explain changes, such as elevation, alcohol, or illness.
Vitals is for wellness purposes only, not medical use. An unusual reading is not a diagnosis, and the feature should not replace advice from a healthcare professional. Apple says the out-of-range algorithm was developed using real-world data from the Apple Heart and Movement Study.
2. Sleep apnea notifications flag possible signs
On Apple Watch Series 9, Series 10, and Ultra 2, watchOS 11 can use wrist movements to monitor breathing disturbances during sleep. The Health app categorizes nightly results as elevated or not elevated and offers views over one month, six months, or one year.

- GET HYPERTENSION NOTIFICATIONS—Did you know that Series 11 can spot signs of chronic high blood pressure? By analyzing how your blood vessels respond to beats of the heart, it can notify you of possible hypertension.*

An algorithm reviews data in 30-day periods and may notify eligible users when it identifies signs of moderate to severe sleep apnea. The feature is intended for people aged 18 or older who have not already been diagnosed. It is not a diagnosis, and receiving no notification does not prove that sleep apnea is absent. Availability depends on regulatory authorization and region.
3. Training Load compares recent workouts with your baseline
Training Load helps you see how workout duration and intensity have changed over time. It compares your most recent seven days with a weighted 28-day baseline and labels the result well below, below, steady, above, or well above your typical load.
Effort is rated on a 1–10 scale. For popular cardio workouts, the watch may estimate an effort rating that you can adjust; for other workouts, such as strength training, you may enter it after the session. The Fitness app on iPhone can show possible implications of continuing at that level, but this is not a medical assessment or a guarantee about fitness or injury outcomes.

5. Pregnancy tracking adds relevant Health support
If you log a pregnancy in the Health app, Cycle Tracking on Apple Watch can show gestational age and let you log pregnancy-associated symptoms. The Health app may also prompt you to review settings such as the high-heart-rate notification threshold. These features support tracking and settings review; they are not medical advice.
6. Smart Stack surfaces useful widgets
Smart Stack can suggest or add widgets based on context such as time, date, location, and routines. watchOS 11 adds widgets including Photos, Distance, and Shazam, along with interactive widgets and Live Activities on Apple Watch.

7. Check In can accompany a workout
You can start a Check In from the Workout app for a session such as a run or a late gym workout, or use Check In in Messages. It lets a friend or family member keep track of the workout’s completion. Treat it as a communication and safety convenience, not emergency monitoring.
8. Translate brings translations to your wrist
The Translate app lets you translate on Apple Watch, and its Smart Stack widget can be suggested when you travel somewhere where the local language differs from your watch language. Apple’s June 2024 preview said Translate supported one of 20 languages and offered romanization for languages using the Latin alphabet; that historical count is not a guarantee of current support in every configuration.
9. Double Tap can scroll through apps
On watches that support Double Tap, the gesture can scroll through any app, making one-handed interaction easier. Apple also provided a Double Tap API so developers can define actions for their apps. Specific behavior can depend on the app and device.
