iSnore

The only thing funnier than a fart; the only sound more annoying than a hi-pitched buzz.
Use if for pranks, use it for tricks, or simply try it to hear some of the world’s most irritating and hilarious snoring sounds.
Pick the snore you want and it gets played in an endless loop. It will even work when you lock the iPhone screen. Put it in your bed and prank your room mates, coworkers, parents or teachers.
You can snore them all you want with iSnore. They might think you’re asleep(and hate you for it), but you’re actually awake and silently laughing.
