See timely widgets in the Smart Stack on Apple Watch
The Smart Stack suggests helpful information or actions that you can take depending on your context—like the time of day or your location. The Smart Stack also shows Live Activities for real-time updates on workouts, timers, and more. When the Smart Stack has an immediately useful suggestion, Apple Watch gently taps your wrist with a hint.
Open the Smart Stack
From the watch face, do any of the following:
Turn the Digital Crown upward.
Swipe up from the bottom of the screen.
Scroll to the widget you want to use, then tap it to open the associated app.
Tip: To access Music, Workouts, or Messages, scroll to the bottom of the Smart Stack.
See Live Activities
Live Activities—app activities in progress such as a workout, a timer, or music—appear at the top of the Smart Stack.
Do one of the following:
From the watch face: Tap the Live Activity at the top of the screen.
In the Smart Stack: Open the Smart Stack (if it’s not already open). If you have multiple Live Activities, scroll to the one you want to see.
To return to the watch face, press the Digital Crown.
