Loser Prank - read brain waves
iOS iPhone Entertainment
LoserPrank is a fun little app to get your friend to show the loser "L" hand on their forehead. Works in two simple modes to get straight to the "L" Hand or you can prank your friend telling them this app can read "theta brain waves" and can guess what color they are thinking. Put the app on the prank screen and hand it them. Once the person puts the phone upright on their forehead the "L" will appear. The "L" also bounces for additional fun when the phone shakes.
