Apple Watch Series 9 has a new feature that lets you tap your fingers together to perform tasks — no need for touching the screen.
Apple Watch Series 9 is the latest and most advanced smartwatch from Apple, and perhaps its most notable feature is a cool new gesture that lets you control it without touching the screen. It’s called Double Tap, and it uses a combination of sensors and machine learning to detect when you tap your index finger and thumb together twice.
Here’s how it works and what you can do with it.
What is Series 9’s Double Tap feature?
Double Tap is a new gesture for manipulating the watch without touching its screen. Using your watch hand, simply tap your index finger and thumb together twice — without having to touch the Apple Watch’s display — and you’ll be able to perform tasks like answering a call. The idea behind the new gesture is to make it easier to use the watch without using your other hand. It’s very similar to the double pinch gesture available as part of the Apple Watch’s existing accessibility mode called AssistiveTouch.

The gesture is made possible “by the faster Neural Engine in Apple Watch Series 9, which processes data from the accelerometer, gyroscope, and optical heart sensor with a new machine learning algorithm,” Apple says. “The algorithm detects the unique signature of tiny wrist movements and changes in blood flow when the index finger and thumb perform a double tap.”
The company said the gesture will be available in an October software update.
What can you do with Double Tap?
The Apple Watch Series 9 Double Tap feature can be used to perform many of the most common actions such as answering or ending a phone call, stopping a timer, playing and pausing music, or snoozing an alarm. When you perform the gesture, you will feel haptic feedback and see a tiny symbol at the top of the screen.
How does Double Tap work?
Double Tap uses the sensors and machine learning capabilities of the new S9 chip that powers the Apple Watch Series 9. The S9 chip is Apple’s most powerful watch chip yet, delivering systemwide improvements and brand-new features, including Double Tap and on-device Siri processing.
This S9 chip uses data from the accelerometer, gyroscope, and optical heart sensor to detect when you perform a double tap gesture. The accelerometer measures the acceleration of your wrist movements, the gyroscope measures the rotation of your wrist, and the optical heart sensor measures the changes in blood flow in your wrist. The S9 chip then uses a new machine learning algorithm to analyse this data and identify the unique signature of a double tap gesture.
