The Corona-Warn-App is a digital health and safety tool for people who are at risk of getting infected with the coronavirus. It helps to protect yourself from getting sick, and it will also alert you if you were in close contact with someone who subsequently tested positive for the virus. The app is a companion app for your smartphone or tablet and is intended to be used in conjunction with the existing health and safety measures. It is not intended for use as a substitute for the measures you should take to protect yourself.

How does it work?

It is based on Bluetooth technology and uses the Google Exposure Notification APIs.

The app can notify you if you were in close contact with someone who subsequently tested positive.

It can also provide information about the current status of the disease.
