How to use the Handwashing feature on the Apple Watch

The ongoing COVID-19 pandemic has caused health-related organizations and governments around the world to come up with ways to encourage people to be more hygienic. One idea that has been adopted around the world is that of regularly washing hands, and doing so for at least 20 seconds to minimize the risk of infection by touch.

Memes have been circulated, proposing songs and other ways people can use to time themselves washing their hands, with social pressure helping to enforce the washing of hands in the first place.

With the Handwashing feature of watchOS 7, Apple has added a function to the Apple Watch that is a fairly simple concept, namely a timer that appears whenever the user starts to wash their hands, counting down from 20 seconds. With the release of watchOS 7, it is now available to enable and use on supported devices.

Handwashing requires users to update their iPhone to run iOS 14, and their Apple Watch to watchOS 7, in order to function.

How to turn Handwashing detection on and off via your iPhone

• Open the Watch app on your iPhone.
• Under My Watch, scroll down and tap Handwashing.
• Tap the toggle next to Handwashing Timer.

How to turn Handwashing detection on and off via your Apple Watch

• Press the Digital Crown and select the Settings app.
• Scroll down and tap Handwashing.
• Tap the toggle next to Handwashing Timer.

How to use the Handwashing timer

• Start washing your hands.
• If the Apple Watch detects correct hand movements and the sound of running water, the timer will appear. It will automatically adjust to have started the timer when it thinks handwashing started, and will show a countdown timer with the remaining time.
• Continue washing until the Apple Watch chimes and displays a "Thumbs Up" symbol.

It is advised to not bother to stop and look at the timer on the Apple Watch, as it will cease the countdown and may stop the timer altogether. AppleInsider has encountered situations where the timer stopped abruptly, such as water being registered as a screen tap, which may be an issue for some users.

Along with the default timer, Apple has also included Handwashing Reminders, which will use location tracking to determine if the user has been outside of home, and has returned. The reminder is to encourage users to wash their hands on arrival at home, again to minimize any bacteria or virus transference to other family members by bringing them into the house.

As handwashing is an important part of staying healthy, especially in the current COVID-19 climate, the Apple Watch collects data on handwashing activities. This includes times when the counter is enacted, how many times the user successfully reaches 20 seconds, the average time spent handwashing, and other data which can be reviewed over a longer period of time.

How to view Handwashing data on the iPhone

• Open the Health app.
• If it doesn't appear in the Summary page when entering the app, select Browse.
• Select Other Data.
• Select Handwashing.

Like other metrics the app tracks, users can see how many times they washed their hands in a day, week, month, or year, as well as how long for, averages, and even timestamped data. This feature may be especially useful for families, with parents able to check if their children are washing their hands sufficiently throughout the day.
