The delivery of the update 1.9.1 for the “Corona-Warn” app started on December 17th. With numerous users, including us, the update reduced the number of risk encounters significantly or even to zero. TECHNOLOGY BUTTON reveals what it is all about.
The latest update of the Corona app has been delivered on iOS devices since Thursday. 48 hours later, Android users should also be able to access the update. In the test on the editors’ iPhones as well as postings from users in the social networks, one thing already becomes clear: the update changes the number of risk encounters for many users, sometimes significantly downwards. But there is no mistake behind it – on the contrary!
Developers of the Corona app explain the change
In the official blog of the Corona-Warn-App, those responsible explain exactly why users are now seeing fe
wer low-risk encounters. Accordingly, no
encounters are withheld, but a better functioning interface for calculating the individual risk was created.
Technically, the second version of the so-called Exposure Notification Framework (ENF) is behind it. This now filters out uncritical encounters better.
In plain language, this means that the app now filters out low-risk encounters that it previously identified as “low risk” (green).

So have the measurements been wrong so far?
You can’t say it like that! You shouldn’t lose sight of the actual purpose of the corona warning app. Corona-Warn is primarily intended to indicate a possible infection with the corona virus. That means, red encounters are, so to speak, the core business of the app. This area worked and is still working. Green encounters were more “nice to know” but not really decisive. With the update to 1.9.1, the focus is only directed away from low-risk encounters and towards the important “red encounters”.
