App works perfect You're an idiot if you expect your phone screen (most likely comprised of LEDs) to give off UV light waves. The app says it mimics the COLOR. Learn to read.
Are you people stupid? People keep commenting that it doesn't work... It SIMULATES a black light && works just fine to make things glow... U really think your phone can magically emit UV rays?? Lol... I swear I can not believe some people can be so stupid... WOW...
