A system, method and apparatus are disclosed for monitoring a mobile device en route to a destination. A user of a monitored device specifies geo-fence regions along a route to the destination. Entry and exit of regions triggers the sending of event notifications to a monitoring device. Event notifications may be sent if an estimated time of arrival changes due to delay. Event notifications may be sent if the monitored device deviates from a planned route by a threshold distance. Event notifications may be sent through a direct communication link between the monitored device and monitoring device or through a location-based service.
