Social distancing apps are being used worldwide as an important action for interrupting the existing chains of infection. Since apps with the purpose of tracing contacts are a novelty, it is important to test them carefully for their functionality and effectiveness. In addition, the constantly changing circumstances make it indispensable that new versions with additional functions are being developed and checked accordingly.
