watchOS 7: how to enable the detection of hand washing | Guide

One of the new features of watchOS 7 highlighted the WWDC20 is the detection of hand washing.

The world health Organization (WHO) recommends washing hands for at least 20 seconds and watchOS 7 aims to automatically detect when we wash the hands and to start a countdown of 20 seconds with a lot of animation. If it detects that we stopped to wash the hands before the time runs out, asks us to go forward.

Although hand washing is important in every situation, this habit has become even more essential during the pandemic of COVID-19 because the virus can be transmitted by contact of the hands.

In watchOS 7, while a user washes his hands, the Apple Watch will show a countdown of 20 seconds on the dial, accompanied by feedback and sound touch to make the process more intuitive, so users will not need to look at the screen.

The best part of the function of the washing of the hands of watchOS 7 is that it works automatically, so you do not need to use any app. The system can identify the sounds of the water and soap when we wash the hands and the combination of these sounds with the movement of the hand triggers the countdown.

How to enable the detection of the washing of the hands in watchOS 7:

  • Open the Settings app on the Apple Watch
  • Scroll down to the bottom and click on the Washing of hands
  • We activate the timer
  • Activate Feedback and haptic (optional)

After you have enabled the function, we can check all the details about every time we washed our hands in the app Health on our iPhone.

  • Open the app Health on the iPhone (requires iOS 14)
  • We are on the Browse tab
  • Click Other data
  • Select Handwashing (currently the voice is in English)

watchOS 7 is currently available as a beta version for developers and should be released publicly in the fall. The public beta will be available by the end of this month.
