Fischerprüfungen (Bundesländer) is an Android application developed by bueffeln.net. This free app falls under the Education & Reference category and is designed to help users prepare for the Fischerprüfung (fishing exam) in various German states, including Baden-Württemberg, Bayern, Berlin, Brandenburg, Bremen, Hamburg, Mecklenburg-Vorpommern, Niedersachsen, Nordrhein-Westfalen, Rheinland-Pfalz, Saarland, Sachsen, Sachsen-Anhalt, Schleswig-Holstein, and Thüringen.

The app is based on an intelligent flashcard system that repeats all the questions, with more emphasis on the ones that users answered incorrectly, until they master the subject matter. The Lern-O-Meter feature helps users track their progress and the app allows them to learn all the questions for the exam or individual chapters. Users can also test their knowledge in a simulated exam mode under real exam conditions and search for questions and answers. The app can be used offline and synchronizes user progress with bueffeln.net, enabling them to learn on multiple devices and customize their learning experience.
