Designed for Mac users with an iPod but no PDA who want to do paperless geocaching complete with descriptions, log entries and hints. Uses the iPod’s “Notes” feature to display complete cache description pages. gpx2ipod is built on top of gpsbabel.
Note: I’m not likely to continue development of gpx2ipod, for two reasons: 1) MacCaching finally grew the ability to store cache metadata in the iPod’s “Notes” feature rather than in the address book (which was the whole impetus behind my developing gpx2ipod to begin with), and 2) I switched to a Garmin Colorado a few months ago, which displays description, logs, and hints directly in the GPS. I no longer need to offload that data to the iPod, so my itch has been scratched. Do with this software what you will!
