According to a newspaper report, the official Corona warning app will be even more expensive for the federal government than originally planned.

As the "Welt am Sonntag" reports, citing the Federal Ministry of Health, by the end of the year, instead of the additional costs of 50 million euros calculated in February, 70 million euros are now expected.

In mid-January, the federal government had spoken of costs of around 130 million euros that had been incurred up to that point.

The total costs paid so far now amount to around 160 million euros, as a spokeswoman for Health Minister Karl Lauterbach (SPD) told the newspaper.

The companies SAP and T-Systems are responsible for the development, further development and operation of the warning app launched in June 2020.

According to the report, the increased costs are incurred, for example, for the "connection of further test sites" or for the "improved display" of the current status proof.

A few days ago, Lauterbach announced that the app would be reprogrammed.

Anyone who has just been vaccinated, tested or recovered, the app will automatically and without delay show green instead of blue - for example in a restaurant this can be seen at a glance, the minister explained.
