How to turn on handwashing detection on your Apple Watch to track your handwashing activity

• You can turn on handwashing detection on an Apple Watch via the watch's Settings app or your iPhone's Watch app.
• The latest version of the Apple Watch's operating system, watchOS 7, can automatically detect when you're washing your hands.
• Handwashing detection runs a 20-second timer to help you wash your hands for the minimum amount of time recommended by the World Health Organization.

With a heightened emphasis on health and hygiene in the news, the latest version of the Apple Watch's operating system, watchOS 7, now includes a handwashing detection feature. It automatically senses when you're washing your hands and provides a helpful timer to ensure you keep washing for the time recommended by the World Health Organization — 20 seconds.

As long as you have a compatible version of the Apple Watch, detection is automatic, based on a combination of hand movement and the sound of running water. It's not foolproof, but should automatically detect handwashing the vast majority of the time.

How to check if your Apple Watch has handwashing capability

To turn on handwashing detection, you need to have an Apple Watch Series 4 or higher. Older watches lack the microphone needed to listen for running water. You also need to be running watchOS 7. Your watch should update automatically, but you can also check manually.
