Does Germany's track and trace app actually work?

Brits are still waiting for their coronavirus track and trace app. Meanwhile, Germany’s version is up and running. But although Germany appears to have beaten Britain again when it comes to tackling the threat of coronavirus, not all Germans are happy with the new app.

The app’s launch coincides with the further easing of lockdown restrictions in Germany, so its success is critical to Merkel’s hopes of keeping her country’s coronavirus death toll relatively low in comparison with elsewhere. It operates by issuing a warning to those who have come into contact with someone who subsequently tests positive for the virus. If a person spent more than 15 minutes within two metres of another app holder who later tests positive for Covid-19, they receive a notification advising them to undergo testing themselves.
