Apple Watch will prompt owners to wash their hand properly

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. The firm announced the new feature at their annual Worldwide Developer Conference on Monday alongside a spate of other updates. Apple said washing hands properly for at least 20 seconds can help prevent the spread of illnesses, such as the deadly coronavirus that put the world in lockdown. It uses the motion sensors, microphones and machine learning to detect when someone starts washing their hands then initiates a 20-second countdown timer. Other new features announced for the wearable device include the ability to swap Watch faces, dance tracking in the fitness app and sleep monitoring.
