German Chancellor Angela Merkel urged fellow citizens to use the COVID-19 tracking app, DW reported.

According to her, those who download the app can control the further spread of the virus.

Merkel noted that the Corona-Warn-App is trustworthy since during its development a lot of attention was paid to the protection of personal data and the highest level of IT security.

She added the use of the app is completely voluntary.

Corona Warn-App is available in Germany since June 16, and it has already been downloaded by almost 10 million people.
