TV KILL

Turn off supported TVs using your device's built-in IR-blaster. The app basically transmits a variety of off-patterns for different TVs successively, which will cause most TVs to power down.

If you activate the repetitive-mode, your phone will transmit the off signals over and over again, even when you close the Application or lock your screen. This way, you can simply deploy your phone in front of a TV and the TV will turn itself off again whenever somebody tries to switch it on. (Great for private screening events)

You can also select an off-pattern that only affects devices from a single manufacturer, in case you want to turn off a TV from a specific brand.

TV KILL also includes a widget for your home screen, so you don't even have to open the app to turn a TV off.
