When you take your phone out of your pocket, an alarm rings until your enter your lock screen security code and enter into your mobile phone.
This will be very useful in public places like Bus Stand, Railway station or Airport where there is a high probability of loosing your mobile phones.
Just switch on this app and put the phone in your pocket and sleep peacefully :)

Note : This app works based on the proximity sensor value changing when taking the device out of the pocket so it will not work in devices that are using the flip covers. Please add PickPocketPolice to the white list of any task killer since this application needs to function when the screen is turned off.Since it uses proximity sensor to detect whether the screen should be on or off, some power consumption is unavoidable. So, if you are using your phone in a secure location like your home, we suggest you to turn off the service using the widget or notification bar or from inside the application screen. Features like Automatic on/off of the service based on the location will be added in future releases.
