How do I turn off Sirius app

If you want to completely shut it down, with Sirius open, hit your home button once to go to your home screen. Then tap your home button twice to bring up the most recently used apps (Task Bar). You'll see the Sirius app on that bottom row. Hold you finger on any app in the bottom row until they all start to jiggle. You'll see a ➖ sign on each app in the uppre left hand corner. Touch the ➖ on the Sirius app and it will completely close. Tap home again to stop the apps from jiggling and again to go back to your home page.
