Apple Watch Series 9, Series 10, and Apple Watch Ultra 2 models include a multi-functional Double Tap gesture that you might not know about or haven't yet got around to trying. Here's everything Double Tap can do, and how you can make the most of it on your Apple Watch.

Double Tap is a gesture-based feature for Apple Watch models that lets you control watch functions by tapping your thumb and index finger together twice. The feature aims to make it easier to navigate the Apple Watch when you have only one hand free, like when you're walking a dog, carrying groceries, or holding a cup of coffee.

What Double Tap Can Do

Double Tap's functionality is pretty simple. You raise your watch to wake, and then you double tap your thumb and index finger together to control what's happening on the screen of your watch.

By default, Double Tap selects the primary button in whatever app you're in. So for example, if you get a call, you can double tap to answer, and use it to hang up when you're done. Likewise, if you're watching/listening to media, you can pause it and resume it (or skip). You can also use the gesture from your Apple Watch face to navigate through your Smart Stack, widget by widget.

Some other use cases: If you've set a timer, double-tapping will pause it. Performing the gesture again will resume the countdown, and when the timer goes off, a double-tap will stop it. Similarly, you can use it to do other everyday things like snooze alarms, trigger the Camera Remote app's shutter button, and dismiss notifications.

As you might expect, the gesture is also set up to assume your other hand is preoccupied. If you receive a text, for instance, a double tap lets you reply with a voice message, while another double tap sends the message.

Here's a rundown of everything you can do with Double Tap:

• Open the Smart Stack from the watch face, and then Double Tap again to scroll through widgets one by one.
• Answer phone or FaceTime calls.
• Hang up phone or FaceTime calls.
• When you get an iMessage, Double Tap to view it, and then Double Tap again if you need to scroll.
• Reply to a Message using dictation and then send it with Double Tap.
• Act on notifications - Apple says a Double Tap on an incoming notification will activate the primary action, such as snoozing a reminder or replying to a message.
• Pause, resume, and end a timer.
• Stop and resume the stopwatch.
• Snooze an alarm.
• Play and pause music, podcasts, or audiobooks (or skip a track, depending on settings).
• Change to the Elevation view in the Compass app.
• Start or stop automatic Workout reminders when a workout is detected.
• Take a photo with the Camera Remote.
• Record a voice memo in the Voice Memo app.
• Change Flashlight modes.

In the Apple Watch Settings app, under Gestures, you can opt to change the playback option from play/pause to skip, and the Smart Stack option from Advance (swaps through the widgets) to Select (opens a widget's associated app). If you have Apple Vision Pro, you'll also find an option to ignore double tap gestures when you're wearing the headset.

How to Set Up Double Tap

If Double Tap is disabled on your watch, you will need to enable it manually for it to work. This can be done from your wrist or in the Watch app on iPhone, and both menus include options to customize Media Playback and Smart Stack functionality.

Note that to enable Double Tap, setup involves giving watchOS permission to disable some Accessibility options, including Assistive Touch, Zoom with Hand Gestures, VoiceOver with Hand Gestures, and Quick Actions. If Double Tap is enabled but is not working for you, disabling it and then turning it back on can help in some circumstances.

On Apple Watch:

1. Open the Settings app.
2. Tap Gestures.
3. Tap Double Tap, then toggle on the switch next to Double Tap on the next screen.
4. If prompted, tap Turn off Accessibility Features at the bottom of the on-screen alert.
5. Choose your preferred setting for "Playback" (Play/Pause or Skip) and "Smart Stack" (Advance or Select).

On iPhone:

1. Open the Watch app.
2. With the "My Watch" tab selected, tap Gestures.
3. Tap Double Tap, then toggle on the switch next to Double Tap on the next screen.
4. If prompted, tap Turn off Accessibility Features in the on-screen alert.
5. Choose your preferred setting for "Playback" (Play/Pause or Skip) and "Smart Stack" (Advance or Select).

Apple says Double Tap is enabled by the S9 chip's faster Neural Engine, which is why the feature is only available on the Series 9 and later and the Ultra 2. Apple said it developed an algorithm that detects the "unique signature" of tiny wrist movements and changes in blood flow when the index finger and thumb are tapped together.

If you own an earlier Apple Watch model that doesn't support Double Tap, you can always try a similar but more limited accessibility feature called AssistiveTouch, which is available on the Apple Watch Series 4 and newer.
