Abstract
Methods, systems, and computer-readable media for forming and tracking a location-sharing group are disclosed. The location-sharing group can be performed ad hoc without the assistance of a central server. A geofence can be defined that encloses the current locations of the participating devices in the location-sharing group. The geographic location of the location-sharing group as a whole can be tracked and provided to the participating devices in the location-sharing group. Group-level location-sharing can be enabled. Departure of a participating device from the location-sharing group can be detected based on the current location and the coverage radius of each device in the location-sharing group. Entry of points of interest into the geofence of the location-sharing group can be detected and notified to the participating devices in the location-sharing group.
