In case you don't read reviews of free apps before downloading them, this might be of interest to you.
Sounds like a cool app if you're a stupid kid who enjoys annoying your whole class (like me.) However, after reading the reviews, I quickly deleted this app. About one in every ten reviews claim that the high-frequency sound actually BLEW OUT the speakers on their device. Only a few mention which device they had (I've only seen iPhone 3G.) So use this app at your own risk.
Sound Grenade gives you instant crowd control. That party get a little bit out of control? Sound Grenade is the answer. Plug your iPod touch or iPhone into some speakers and crank up the volume. Sound Grenade generates a really, really annoying, nauseating and headache producing high pitched sound.
You can use it with just the device's inbuilt speaker as well. If you are at a dinner party, and want it to end, turn on sound grenade in your pocket. No one will be able to work out where the sound is coming from.
Disclaimer: Use this app sensibly. Don't over amplify. Playing any sound or music at a high volume for an extended period of time can damage hearing. Please refer to the standard App Store EULA for more information.
