DSA Reise is a free Android app developed by Joerg Ruedenauer that serves as a travel companion for fans of the role-playing game "Das Schwarze Auge" (DSA). The app offers a range of features such as events, calendar, weather, and travel times.

The events section allows users to enter random events or holidays that occur during their game sessions. The calendar feature includes the day of the week, moon phase, and several time systems to choose from. The weather section determines climate zones and months based on the "Wege des Meisters" or "Wege des Entdeckers" rulebooks and provides maximum and minimum temperatures.
