The new NHS COVID-19 app, now available to download for free in England and Wales, is the fastest way to see if you're at risk from coronavirus.
The faster you know, the quicker you can alert and protect your loved ones and community.
The app has a number of tools to protect you, including contact tracing, local area alerts and venue check-in.
The app will not hold any personal information about you or track your location. The app tracks the virus not individuals.
It uses proven technology from Apple and Google, designed to protect every user’s privacy. Read more detail about protecting your privacy and security
