Not solely that, the app will present a countdown timer. “Once you attain the top of your self-isolation interval, you’ll obtain a notification with a hyperlink to the most recent recommendation for you,” it clarified on Twitter following the confusion.

The so-called Publicity Notification API makes use of Bluetooth Low Vitality to find out whether or not – in some unspecified time in the future over the past two weeks – you’ve got handed somebody who later exams optimistic for the novel coronavirus.
