A method and system are provided for monitoring and controlling a mobile device using a supervisory device. In some embodiments, the supervisory device operates in conjunction with the mobile device to monitor an extent of usage of the mobile device as well as to ensure that certain software is being used appropriately. The supervisory device may take one or more responsive actions when an extent of usage of the mobile device reaches a threshold extent of usage, when certain software on the mobile device is not being used appropriately, and/or when certain settings of the mobile device have been changed. The supervisory device may operate in a non-permissible mode and determine that the mobile device is currently enabled. In response to this operation and determination, the supervisory device may disable the mobile device and/or transmit to an external device a notification message.
