A personal safety service notifies a pre-defined group of emergency contacts about an occurrence of emergency associated with a user. To do so, a personal safety service server comprising a processing device and a memory receives an indication of the emergency and a location of the emergency from a wearable mobile device and sends a notification message via a push notification displayed on user devices of a predefined group of emergency contacts indicating the occurrence of the emergency. The personal safety service server periodically receives updates to the location of the wearable mobile device from the personal safety service client application.
