Hi,
I wrote a little piece of software called "pygcstats", which generates various statistics on your found geocaches.
pygcstats works as follows:
It reads your 'my finds' GPX-file (to be generated via Pocket Query) and builds statistics on finds, dates, containers, cache types, locations etc. based on that. Furthermore, since version 0.6., badges and awards can be added.
pygcstats can be run via a local HTML-based user interface or via the command-line. The progam works completlyl offline, no network connection needed.
Furthermore, as pygcstats is written in Python, it runs cross-plattform on Windows, MacOS and Linux (assuming you have Python installed).
Last but not least: it's absolutely free, actually it is release under an Open Source license.
Interested? Just visit the project page at launchpad.net/pygcstats where you can get the latest version. Furthermore, there's a link to the full documentation (English and German), which is available either online or as an PDF file.
Regards,
Jochen (from the GC-Team DerSchnelleLinus)
