Your Apple Watch Now Knows If You’re Washing Your Hands Properly

So you don't have to sing "Happy Birthday" twice.


( Aside from physical distancing and wearing a face mask to avoid getting infected by COVID-19, another measure recommended by health agencies is proper handwashing—which should be done for at least 20 seconds, and entails rubbing soap on your palms, between fingers, and the back of your hand. You can sing “Happy Birthday” twice (or any other pop song that comes from now-popular hand-washing lyrics generators) to make sure that you’re doing it long enough. But tech company Apple has another thing in mind: a watch that detects if you’re washing your hands in less time than it takes to sing “Happy Birthday” twice over. News about the watchOS 7 update dropped on June 22.

With the new software, your Apple Watch automatically detects that you've begun washing your hands through the sound of running water and squishing soap. It shows a 20-second timer on your watch's face, complete with the sound of a bubble bursting for every second. When it detects that you've stopped washing, it shows a reminder to "Keep washing"; otherwise, a "Well done" message appears with a quick vibrate. It also prompts you to wash your hands when you get home.


Other new features of the watchOS 7 include: customizable and colorful watch faces, a sleep tracker, fitness metrics for additional workout options like dance and core training, a map with bike-friendly routes, and translation care of Siri.
