The KnubbiApp is the App for the Knubbenschützen Münster-Gremmendorf e.V. from 1955. It contains a comprehensive presentation of information about the club and it's living. In Detail these are actual dates, the members of the board and the officer corps as well as information about the kings and kaisers of the Knubbenschützen. The update of the Information is at preset intervals or on demand. As You can see at the screenshots, data retrieved from the web pages of the Knubbenschützen (http://www.knubbenschuetzen.de
) are not (and can't be) localized, they exist only in german.
Since version 1.9.6 it is possible to select in the settings a calender to integrate the dates of the Knubben with it. Due to the availability of a calendar interface, this option needs at least android 4.
