Tatbestandskatalog is an Android app developed by Witoslaw Koczewski under the Education & Reference category. The app is designed to be a searchable list of traffic offenses and their corresponding fines, driving bans, and points. The offenses are grouped according to the underlying law.

The app is primarily intended for police officers in the federal states and employees of municipal traffic fine authorities but can be used by anyone. Based on the BT-KAT-OWi, which is available as a PDF on the internet, the app is a private project.

With Tatbestandskatalog, users can easily search through the list of offenses and find specific information, such as the fine amount and driving ban duration, making it a convenient tool for traffic law enforcement personnel. The user interface is straightforward and easy to navigate, ensuring that users can find the information they need quickly and efficiently.
