A clever new app which turns the iPhone into a personal attack alarm has just been launched. KamAlert 1.01, has a motion detector surveillance camera built-in, panic buttons for medical emergencies, and can send for help automatically.

Released by Informatica Kamalert SL, the abduction in 2007 of Madeleine McCann in Portugal was the inspiration behind the creation of this app. If there is an intruder, the motion detector will start taking photos to send to the police for evidence.

Users have the option of choosing who they want to receive any alerts, so a quick tap of the panic button is all that is needed to send distress messages.

In the case of an emergency, authorities can locate users with the aid of GPS, and distress messages can be sent via a phone call, emails and SMS. The app is available in US English and Spanish. KamAlert 1.01 is on the App Store for only  $4.99. iPhone 3G, 3GS required with OS 3.1 or later.
