To use the Apple Watch handwashing timer, open Settings on the watch, tap Handwashing, and turn on Handwashing Timer. After that you don’t start anything yourself: when the watch detects that you’re washing your hands, it runs a 20-second countdown and encourages you to keep going if you stop early.
These steps follow Apple’s guide to setting up Handwashing on Apple Watch for watchOS 27. Apple’s current list of models that support Handwashing is Apple Watch SE 3, Series 9, Series 10, Series 11, Ultra 2 and Ultra 3. Apple Watch Series 12 and Ultra 4 are not on that list.
How to Turn On the Apple Watch Handwashing Timer
- Press the Digital Crown and open the Settings app on your Apple Watch.
- Scroll down and tap Handwashing.
- Turn on Handwashing Timer. The switch turns green.
The timer is now ready. The watch starts the countdown on its own when it detects handwashing.
If the Settings icon is hard to pick out, you can change your Apple Watch app view to a list so every app shows its name.
Turn it on from your iPhone
- Open the Apple Watch app on your iPhone.
- On the My Watch tab, scroll down and tap Handwashing.
- Turn on Handwashing Timer.
The setting syncs to your paired watch.
What Happens When You Wash Your Hands
Apple says the watch uses its motion sensors, microphone and on-device machine learning to recognize handwashing motions and the sound of running water. When it detects both, a 20-second countdown appears on the screen, which matches the time global health organizations recommend. If you stop before the 20 seconds are up, the watch prompts you to finish.
- What you’ll notice: a tap on your wrist and a countdown on the screen.
- When you’re done: testers report a chime and a confirmation on the screen when the countdown finishes.
- Keep scrubbing: don’t pause to look at the watch, since stopping your hands can end the countdown early.
- Wet screen: water on the display can register as a tap and stop the timer, so a short countdown doesn’t always mean you stopped.
On privacy, the sounds used to detect handwashing are not automatically recorded or saved by the Health app or Apple Watch.
How to Get Handwashing Reminders
Handwashing Reminders is a separate setting that reminds you to wash your hands shortly after you get home. In the Apple Watch app on your iPhone, go to My Watch › Handwashing and turn on Handwashing Reminders. The switch appears once Handwashing Timer is on.
For the reminder to work, the watch needs to know where home is. Add your home address to My Card in the Contacts app on your iPhone, and make sure Location Services is on. On an Apple Watch you manage for a family member with Family Setup, turn on the reminder on the watch itself in Settings › Handwashing.
How to See Your Handwashing History
- Open the Health app on your iPhone.
- Tap Browse.
- Tap Other Data, then tap Handwashing.
You see how many washes the watch logged and your average handwashing time, by day, week, month or year. To keep this chart on the Summary tab, scroll down on the Handwashing screen and tap Add to Favorites.
If the Handwashing Timer Doesn’t Start
- Handwashing is missing from Settings. Check your model against Apple’s list above. Older watches that can’t run watchOS 27 may still show the setting on the version they have, but Series 12 and Ultra 4 are not on Apple’s current list.
- The switch is on but nothing happens. Wash under steady running water and move your hands normally. Detection needs both the water sound and the motion, so lathering with the tap off won’t trigger it.
- The countdown stops early. Keep your hands moving and avoid splashing the screen.
- Handwashing Reminders won’t turn on. On your iPhone, open Settings › Privacy & Security › Location Services and make sure it’s on, then confirm your home address is on your contact card.
- Still not working. Restart the watch and iPhone, then install the latest updates. For help, read about updating your Apple Watch.
How to Turn the Handwashing Timer Off
Open Settings on your Apple Watch, tap Handwashing, and turn off Handwashing Timer. You can also do it in the Apple Watch app on your iPhone under My Watch › Handwashing. Your past handwashing data stays in the Health app.
Other automatic health features have their own switches too, including heart rate tracking on Apple Watch.
Frequently Asked Questions
Can I change the timer length?
No. The countdown is fixed at 20 seconds, and there’s no setting to change it.
Does the handwashing timer use the microphone?
Yes. It listens for running water and combines that with motion data, which is how it tells handwashing apart from other movements. The sounds aren’t automatically recorded or saved.
Is this the same as the water drop icon on my watch?
No. The water drop icon means Water Lock is on. See what the icons on Apple Watch mean for the full list.
