Started officially in 2000, coinciding (but not by coincidence) with a more-accurate GPS network. Long before what would now be considered “smart” devices (Palm Pilot, Handspring Visor, etc) had any sort of GPS abilities. You had to have, or know someone who owned, a handheld GPS device.
Geocaching isn’t limited to a single app… Go find a geocaching website and punch the coords into whatever mapping app you use.
I thought it was all through groundspeak.
