A Prank Crank FREE

       iOS iPhone

Notice: This app is intended for entertainment purposes only and does not provide true battery charging functionality.


This is the first app, that allows you to charge your iPhone/iPod/iPad battery without any equipment like a cable.

After much basic research with the assistance of various Central European universities we have developed a software. This app convert indexed friction thermal energy into electrical energy. This energy is used to recharge the battery.
So it's quite simple - turning the crank as long as the battery is fully charged. :D

You can charge your battery in the contest mode as fast as you can. Share your charging time with the whole world.

● Features ●

✓ contest mode
