Alert your friends when grenades are in the area!
Pressing the widget button will unleash a loud vuvuzela sound. You can even make it sound like a noisy soccer stadium by rapdily pressing the button over-and-over again.
IMPORTANT: To use it, you must long-click your home screen and add the Grenade Whistle Widget. You can NOT run it like a normal application, sorry.
I've just released some new widgets! To check them out, scroll down to "View more applications". Enjoy :)
