A simple "dead man switch" application. This app will ring an alarm at intervals configured by the user. If the user fails to acknowledge it, it will send a text message to a predefined telephone number containing the location of the mobile and the hour at which the user stopped responding. It can send different messages as the correct location gets progressively refined. This messages *will* cost you money so use with care.
