According to at least one aspect, a system and corresponding method for detecting and reporting personal emergency events includes a mobile application running on a client device of a user and a backend application running on a backend system. The mobile application and the backend application can communicate on a regular basis. The mobile application or the backend application can regularly monitor sensor data, user contextual data or other data indicative of user state of health, activities or environment and detect or predict an emergency event of the user based on the monitored data. Upon detecting an emergency event, the mobile application or the backend application can warn the user or notify emergency contacts of the user of the emergency event. The backend application can use the sensor data or other user data to update an emergency predictive model specific to the user employed to detect or predict emergency events.
