Smart Stack in watchOS was introduced in watchOS 10. It’s a widget hub accessible by turning the Digital Crown up or swiping up from the bottom of any watch face.
It intelligently displays relevant information, widgets, and Live Activities (timers/workouts). You can customize it by holding a widget to add, delete, or pin apps.
