Dreckpetze is a new Android app developed by wer denkt was GmbH, available for free in the Travel & Navigation category. The app aims to involve the community in maintaining cleanliness in Dortmund. Users can report instances of littering or dirty public spaces to prompt quicker action. Dreckpetze facilitates notifying the appropriate authorities, such as the Environment Department of the City of Dortmund, in cases where immediate action is needed. While not always able to provide instant solutions, each reported incident contributes to a cleaner environment in the city.

City Cleanliness is everybody's business, and Dreckpetze empowers residents to take action for a cleaner Dortmund.
