If two cell phones and thus their owners, to approach at least 15 minutes on two meters or less, it is stored potentially contagious encounter in a “contact diary” on the Smartphones. The phones use anonymous numbers that cannot be traced back to the owner.

This 2.5 to 3.5 million euros per month for the operation. 20 million euros would mean that for three months around 500 developers have screwed with an annual salary of 150,000 euros to the App. Thus, an extremely high effort, however, is hardly realistic. Whether and where money is being frittered away, it could still be the interesting question.

7. How reliable is the Corona App?

Bluetooth is not actually intended to constantly measure distances between Smartphones. In addition, for example, panes of glass between the two mobile phones can distort the results.
