Sound Grenade

By High Gloss

Open iTunes to buy and download apps.


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.

-Motion activated
-You cant turn it off unless you tap the screen with three fingers or quit the app!

-Great for stealth attacks!

-Play with the sliders and watch people's heads spin

Glitched and terrible!!!!!!!! 💀💢💥

This app was working pretty well at first, but then when i hit the deactivate but to stop the sound, it wouldnt turn off. Then it kept going after i exited the app. And going and going!!! At first i thot i was just still hearing it. But it wouldnt stop even though i closed the app and turned off my phone!!

It always annoys people

Somehow I've become immune to the sound, but everyone else in my family hates it!
It's really fun to annoy people with this

And I haven't ever had any crashes...


If the app crashes just restart your device should work again. Only thing is I wish there were more grenades
