More than 2.4 million people downloaded the app within 48 hours of its release, the Government has revealed.
The app uses encrypted Bluetooth communications between phones to register when smartphones have been within 1.5m of one another for at least 15 minutes and can be used by health officials if a user tests positive to COVID-19.
The voluntary app has received the backing of by doctors, nursing, business and banking groups, and is tipped to play a major role in streamlining the process of identifying contacts after a person tests positive for coronavirus. It also helps patients quarantine themselves faster and access treatment.
