The NHS COVID-19 app is no longer in use and the Isle of Wight trial has now ended. This is archived information from 18 June 2020. If you still have the app, please uninstall it.

The NHS COVID-19 app is designed to be used by one person per mobile device. You will still benefit from other people downloading the app, even if you do not have a smartphone yourself. This is because, at any level of uptake, the app will support the NHS's wider programme to stop the spread of the virus, called NHS Test and Trace.

The NHS Test and Trace service will help stop the spread of the virus by contacting those who test positive for coronavirus to gather information about their recent interactions with others. This could include household members and people who they’ve been in direct face-to-face contact with.

The NHS COVID-19 app will improve the NHS Test and Trace service even further by automating the process to inform those who are unknown to, but have been in contact with, someone who has tested positive for coronavirus. For example, someone they sat next to on a bus.

Phone tracing and the NHS COVID-19 app can both be used to advise people who have been in significant contact with an infected individual on what action they need to take (for example, to self isolate) to reduce the spread of the virus. This decreases the risk for everyone of contracting the virus, saving lives and protecting the NHS.

The app will also help us to better understand both where the virus is spreading and how fast it is spreading in different locations. This information could be used, for example, to better coordinate local responses to cases in the area.
