It is being released across England and Wales to support the huge Test and Trace effort.
Studies have shown that the use of technology could reduce infections and deaths by up to eight per cent.
The app uses an Apple and Google-developed system, using Bluetooth to keep an anonymous log of people a user has been close to.
It does this by exchanging randomised keys while the Bluetooth signal strength measures proximity.
If someone falls ill, they can tell the app, and close contacts will be automatically sent a notification and given guidance.
A QR code scanning feature allows people to check-in to venues they visit and share their contact details for human tracing efforts.
