7-Tages-Inzidenz is a free Android application developed by Dieter Thiess. This lifestyle app falls under the category of Health & Fitness and allows users to view the 7-day incidence value from their current location. Additionally, it provides the value of other counties using the search function. With the homescreen widget, users can always have the value for their location in view.

The app uses the official API of the RKI to determine the data. It sends the GPS coordinates of the location or the searched district to the API for data retrieval. The app requires location permission to determine the current position. The widget must have location permission "always" given so that the widget is updated, even if the app is not running.

Overall, 7-Tages-Inzidenz is an essential tool for those who want to monitor the 7-day incidence value in their area. The app is user-friendly, straightforward, and accurate.
