A wearable device may connect to a wearable device over a short-range wireless connection. The user device may receive sensor data from the wearable device, where the wearable device has sensors. The user device may determine that a safety alert parameter has been met, and in response generate an audible alarm. The device may then determine that the connection between the user device and the wearable device has been disconnected, and in response, generate a second audible alarm.
