How does Double Tap work on the Apple Watch?

Double Tap is a new function on the Apple Watch Series 10, Series 9, and the Apple Watch Ultra 2. This allows you to easily control your watch with 1 hand. When you tap your thumb and your index finger twice, you perform actions. For example, you can accept calls or pause your music. This is useful if you have your hands full or want to respond quickly.

Thanks to the new S9 chip, the Apple Watch recognizes the difference between tapping your thumb and index finger twice and other hand gestures. You can use the gesture to operate the main button of an app. For example, you stop a timer or pause your music. You can also take a group photo unnoticed with the remote for your iPhone camera.
