The NHS COVID-19 App is part of the large scale coronavirus (COVID-19) testing and contact tracing programme and will be used, alongside traditional contact tracing, to notify users if they come into contact with someone who later tests positive for coronavirus – helping to keep us all safer. The NHS COVID-19 App alerts people at risk of coronavirus, asking them to isolate before they potentially pass the virus on to others as well as providing local area alerts and QR venue check-in. The app will help the NHS understand if the virus is spreading in a particular area, and so local authorities can respond quickly to stop it spreading further and save lives. The app does this while protecting a user’s anonymity. Nobody, including the government, will know who or where a particular user is.
