Every person who downloads the NHS COVID-19 app will be helping in the fight against coronavirus (COVID-19). The app will help the NHS understand where and how quickly the virus is spreading, so we can respond quickly and effectively. The app helps the NHS track the virus, not individuals.

The app is part of our large scale coronavirus testing and contact tracing programme called the NHS Test and Trace service in England and NHS Wales Test, Trace, Protect in Wales.

Alongside traditional contact tracing, the app is used to notify users if they come into contact with someone who later tests positive for coronavirus. The app also allows people to report symptoms, order a coronavirus test, and check into venues by scanning a QR code.

The app does all this while protecting users' anonymity. Nobody, including the government, will know who or where a particular user is. Read more about your data and privacy.
