The only application which can restrict operation of other applications even if a home button is pushed!! A loyal watchdog to guard your privacy. It barks if the phone is touched. Continues barking even if the home button is pressed. The watchdog stops barking after 30 seconds but will start barking again if the phone is touched. All touch operations and movements of your iPhone are reported to you. Your very own watchdog to protect your privacy!! (Important) Your iPhone should be set to the following configuration to ensure "Watchdog!" can be used effectively.

Configuring your iPhone in this way allows you to restrict other apps even when running in the background.
