Black light? Not really. Doesn't work at all. Just a dim blue/purple light, that doesn't make white fibres glow like a real black light. Nice idea though.
Works! The screen is definitely capable of delivering a weak simulation of uv light. Not perfect but it works for an app. If you want perfect uv light, get a florescent blacklight bulb.
Crap No tablet or cell phone is going to be able to give off light in the 350 to 410nm wavelength. You'd need flourescent or mercury vapor bulbs. No LED, OLED, or Plasma screen can do it.
Did what I needed Just wanted to charge my glow in the dark stars and it worked very well. Held it about 3 minutes and my stars glowed brightly!
Doesn't even work It's literally just a purplish light which doesn't even wirk. Please don't waste ur time on this stupid app
Cute Novelty Idea A novel idea but as expected it didn't work as an actual black light.
