100 days of the Corona warning app: Even before the Spahn balance sheet, Telekom speaks of "the population's vote of confidence"

In no other western country has a comparable application been downloaded as often as the application from the

Nevertheless, critics repeatedly speak up who question the effectiveness of the app.

These doubts are also fed by technical inadequacies.

The developers of the application,

The app uses

However, Bluetooth was never developed for this task.

Therefore, the creators of the app have to calculate with values ​​that are often not exact.

The contact determination via Bluetooth is not the only function of the app.

The application also calculates the risk, which results from the total time of all

If the app shows an

100 days of Corona warning app: iPhone dropouts - number of active users significantly lower than downloads

During the first 100 days, this risk assessment did not always work reliably.

So it turned out that the app on the

After several attempts, this error was corrected in cooperation with

This has mainly

with the

According to the RKI, the app has now been

Experts estimate that 15 million people in Germany actively use the application.

This also corresponds to the order of magnitude of the daily access to the Telekom server, where the app downloads the list of all daily keys from the smartphones that are associated with positive test results every 24 hours.

SPD health expert Karl Lauterbach on Corona warning app in Germany - "It is underestimated"

The application could work better than expected, however, if groups with an above-average risk of infection use the application more often than the average.

On this connection, among other things,

The app can still make a major contribution because it is used a lot in the age group that is particularly affected.

In addition to additional information for users in the app, the SPD politician would like

“This knowledge has to be built into the app.

It is high time for a Corona Warning App 2.0 so that the app can help you get through the upcoming Corona winter. ”(Dpa / frs)
