Volt

Volt is a simple application that allows you to turn your iOS device into a ball of lightning, filling the screen with spectacular effects.

One of the app's most fun features allows you to choose a side of the Force and turn your smartphone into battleground with different colors of Jedi lightning (from Star Wars).

Another interesting way to use the app is to set the lightning as your wallpaper, which gives it a dynamic look whenever you unlock the screen to do what you need to do.

Volt is a peculiar application that, though it might technically be useless, provides plenty of entertaining moments. And who wouldn't enjoy seeing their phone produce bright flashes of lightning?
