SD card required
With this application you can easily train your vocabulary with the 5-box-system, no matter what language!
The vocabulary files themselves must be created, but there are already examples present.
The application creates a folder called "Vokabeln" on the SD card. There the files must be stored.
The contens of the files is organized as follows:

Front|Back|Boxnumber

The Boxnumber is a digit between 1-6

Example:

Baum|tree|1

This example shows a flash card. On the front "Baum" and on the back "tree" in tray 1. Tray 1 should always be provided with new vocabulary.
Of course, several vocabularys are possible in one file:

Baum|tree|1
Haus|house|3
Ball|ball|2

The files can contain empty lines and lines that begin with '#' are treated as a comment:

#Lesson 1
Baum|tree|2
#Lesson 2
Haus|House|5

Additional vokabularies can you download here:

When you've created some vokabulary files, you can send them to jan.dev@gmx.de, so I can add them to a new release.

If you have questions or suggestions, please state them as a comment.
