A lot of Geocache descriptions contain encoded information that must be decoded to solve an excercise and finaly find the Geocache. myGEOtools.de provides a growing number of code tables designed by the geocaching community.
CodeTables is a client application for downloading and displaying code tables from myGEOtools.de.
Note for V1.2: I saw some new "Out of memory" errors in the crash logs. It seems, that some code tables are too big for small devices. If this happens all the time, please send me an email with the device you are using and I'll check what I can do.
