One of the apps is great for pranking my teenage son - it's the Directv app. My husband can change the channel with this app and not touch the remote. The Teen thinks there is something wrong with the TV. It cracks us up!
This app is great for our marriage, too - hubby can channel surf to his heart's delight and let me watch tv in peace. Drove me crazy when he channel-surfed with the remote. He'd always put the tv on the channel menu and then leave the room.
