About this app

SBF Questions is a questionnaire learning app to prepare for the German pleasure boat piloting license for inland waters (IWM) called Sportbootführerschein Binnen (Sbf Binnen), coastal waters (CWM) called Sportbootführerschein See (Sbf See), Lake Constance called Bodenseeschifferpatent (BSP) as well as the maritime radio licenses like Short Range Certificate (SRC), Long Range Certificate (LRC) or inland radio certificate UKW Binnenschiffahrtsfunk (UBI). You can test the app for free with a limited questionnaire and purchase the desired content from the app. The app prepares perfectly for the theoretical boat piloting exam or the examination for the radio certificate.

The App is only available in german.

The following tickets are available as in-app purchases:
* Boat license questioners for coastal waters (CWM) called Sportbootführerschein See (Sbf See)
* Boat license questioners for inland waters (IWM) called Sportbootführeschein Binnen (Sbf Binnen) as well as inland water sialing (IWS)
* License for Lake Constance, called Bodenseeschifferpatent (BSP)
* VHF inland navigation radio (UBI)
* Restricted radio operator’s certificate (SRC – Short Range Certificate)
* Generally radio operator’s certificate (LRC – Long Range Certificate)
* Certificate of expertise for distress signals (FKN)


This app replaces the previous version of SBF questions. The old app is still functional, but no longer visible in the app store.


* Understand the answer: the questions are supplemented with many additional explanations and pictures
* Keyword-based learning: The relevant words are marked
* Learning pedagogy: card index system
* Additional explanations and additional illustrations


>>> LEARN (for long-term memory)
In the background, the app works with the Delius Klasing card index system developed for electronic media, inspired by Sebastian Leitner's learning method. This supports sustainable learning as with the use of a classic index card learning box system.
It can be learned both chapter by chapter and the entire catalog of questions. Statistics provide information about the learning progress at any time.
The most important keywords are highlighted in the answers to make learning easier.

>>> EXAM SIMULATION (knowledge check)
The official examination papers are displayed in the app. If you already have a driver's license or radio certificate and indicate this in the app, the number of questions is automatically reduced - just like in the real test.
You work under the same time limit as in the exam – a realistic exam simulation.
