GeoKrety (from Greek: geo, "earth" and Polish: krety, "moles") is an on-line tracking service targeted at Geocachers. Each registered object, called a GeoKret (plural: GeoKrety), has a unique tracking code, allowing its movements between locations such as Geocaches to be tracked and registered on the service. While the idea behind trackable items such as GeoKrety originated with the geocoin and travel bug, Geokrety is an independent trackable service that can be used with any geocaching activity.
