Apple's latest Watch update encourage users to wash their hands properly by showing them a 20-second timer on their wrist while they are doing it. Other new features announced for the wearable device include the ability to swap Watch faces, dance tracking in the fitness app and sleep monitoring. It will 'also conveniently remind the user to wash their hands when they return home,' Apple said in a statement about the update. The watch announcements were made from the Apple Campus fitness centre, further highlighting the focus on the device as a health tool.
