Ways to customize Double Tap on your Apple Watch Series 9, Watch Ultra 2

Apple
The Double Tap feature on your Apple Watch Series 9 or Watch Ultra 2 offers a convenient way to interact with your device. While it currently has some limitations, it still provides useful functionality. Right now, it's limited to audio playback and the Smart Stack. The Smart Stack, introduced in watchOS 10, is a collection of widgets accessible by swiping up from the bottom of the screen or using the Digital Crown.
