The redesigned Apple Watch SE delivers the core Apple Watch experience at a new starting price

• With international roaming coming later this fall, users can stay connected to a cellular network while traveling abroad. Plans can be extended to Apple Watch from iPhone for little or no additional fee and will be available with over 30 carriers worldwide.⁴

• Users who are diagnosed with AFib can turn on the FDA-cleared AFib History⁵ feature and access important information, including an estimate of how frequently their heart rhythm shows signs of AFib, providing deeper insights into their condition. Users will receive notifications with an estimate from the previous week and also have access to a detailed history in the Health app on iPhone, including lifestyle factors that may influence AFib, like sleep, alcohol consumption, and exercise. In addition, users can download a PDF from the Health app on iPhone that details the history of their AFib and lifestyle factors, which can easily be shared with doctors and care providers for more informed conversations. The first-of-its-kind AFib History feature in watchOS 9 has received a number of local clearances and approvals from health authorities around the world, and will be available in more than 100 countries and territories, including the US, Australia,⁶ Canada, Europe, Hong Kong, Mexico, South Africa, the UK, and more.

• The completely redesigned Compass app in watchOS 9 surfaces more in-depth information and three distinct views. The app displays a new hybrid view that simultaneously shows both an analog compass dial and a digital view. Turning the Digital Crown reveals an additional view that includes latitude, longitude, elevation, and incline, as well as an orienteering view showing Compass Waypoints and Backtrack. Backtrack uses GPS data to create a path showing where the user has been, which is useful if they get lost or disoriented and need help retracing their steps. It can turn on automatically in the background when off the grid. Compass Waypoints are a quick and convenient way to mark a location or point of interest directly in the app. Tapping the Compass Waypoint icon drops a waypoint. Selecting one provides a targeted view of the direction of the waypoint and an approximation of how far away it is.

• The Workout app in watchOS 9 includes new in-session views, such as Segments, Splits, and Elevation, that offer more precise workout data. Users can also improve their training with advanced workout experiences, including Heart Rate Zones, Custom Workouts, Pacer, and, coming later this year, Race Route. For triathlons or activities with any sequence of swimming, biking, or running, the new Multisport workout uses autodetection to easily switch between workouts and records transition times. watchOS 9 also brings more data and features to help track how efficiently users run. New running form metrics, including Stride Length, Ground Contact Time, and Vertical Oscillation, can all be added as metrics on Workout Views.

• Sleep tracking in watchOS 9 provides even more insights with the introduction of sleep stages. Apple Watch uses signals from the accelerometer to estimate when users are in REM, Core, or Deep sleep. Sleep stage data can be viewed directly on Apple Watch in the Sleep app, and users can view more detailed information in the Health app on iPhone, including interactive sleep stages charts, as well as time asleep alongside heart rate or respiratory rate, in sleep comparison charts.

• The new Medications experience on Apple Watch and iPhone helps users manage and track their medications, vitamins, and supplements, allowing them to create a medications list, set up schedules and reminders, and view information on their medications in the Health app.⁷
