Geocaching Challenge Checkers

I have written some geocaching challenge checkers. All of these checkers are web-based: they run entirely in your web browser so will run on any operating system. Please see the links on the left for the currently available checkers.

The challenge checkers are all based on a library I wrote to parse the "My Finds Pocket Query" from the pocket queries page of your profile on geocaching.com. It is very easy to implement extra web-based checkers using this library, so if you have any suggestions for challenges, please get in touch.
