The idea behind a contact tracing app is simple — when a patient tests positive for the virus, the app works backwards and identifies the people who the patient has been in direct and indirect contact with recently, as these other people may have been exposed themselves. This is done repeatedly, creating a network of “safe” and “exposed” people. Google and Apple recently announced a joint partnership to build a large-scale contact tracing app. Governments are in on this race too — Singapore and South Korea have apps live right now, and the UK has one set to launch within days.
