How the app uses Bluetooth technology
Why we’re using Bluetooth technology
The app uses wireless Bluetooth technology to record distances between your phone and other phones with the app installed. Bluetooth tracking will work as long as the app is running, even if it’s in the background.
Bluetooth technology and phone performance
The NHS COVID-19 app has been designed to work in the phone's background, alongside other Bluetooth features and devices being used.
If you notice the NHS COVID-19 app interfering with your other Bluetooth devices, report a technical problem using our online feedback form. Tell us the model of your phone, and which device or app is being affected. Your feedback will help us to improve the NHS COVID-19 app.
