The NHS Track and Trace COVID-19 app is now available to download to help control the spread of coronavirus.
There is a section to allow you to check symptoms of the virus, read the latest government advice, book a test, enter a test result and check into venues with a QR code scan.
From Thursday, businesses will be required by law to display the official NHS QR code posters to allow app users to check in with their phone camera.
The contact tracing element of the app works via Bluetooth and will log the amount of time you spend near other app users, as well as how close you were to them.
If someone near you later tests positive for COVID-19, you will be alerted on the app, even if you don’t know the person.
The app claims it does not hold personal information, such as your name, date of birth or address, with a focus on tracking the virus, not people.
The UK’s major mobile network providers, such as Vodafone, Three and EE, have all confirmed that activity on the app will not come out of customers’ data allowance.
