Reviews for Black Light

Used it to see yellow highlighter and same color pen. Helped the writing pop out. It is a simulator not actual black light.

looking at my background lighting up dust I was thinking if theres a black light app for a phone of course there is kinda works ... although I wish it wasnt a complete novelty light and actually produced whole screen purple light

Um disappointed on the fact that this app doesn't have a flashlight link up and the fact that it doesn't work even in the darkest hours of the night very disappointed cause it had a lot of good reviews and this is very disappointing guys u just lost a valuable contribution to ur app

Actually just curious about HOW the led lite for the camera could be a black light. it Isn't. The Screen is the simulator! KOOL! Works just fine with that limitation in mind. Thanks for the toy!

Super cute app,at first glance it is a simple addition u download.It is easily to use and forget to investigate further.I like the colors and the simplicity of it.But I believe I will put it on all my devices.Its a fun app to share and it's constantly being updated.I like it.If you are working a puzzle it may be a piece.

Not a true blacklight, it's just a purple-hued picture of a light. I shone it on my hands which I had dusted with blacklight powder. It should have been neon af, but nope. I then used a true blacklight on my hands, and they lit up like no-one's business.

Duplicates black light perfectly, and I like option for putting brighter backgrounds. Just an idea but screen edge lights to have on without window open would be magyk.

Are people really that naive or gullible..? It's just a color. Your phone doesn't have the capability to output the UV wavelength to make fluorescent objects glow. just a con to show you ads.

Works!!... It's ur actual screen that shows literally a black (purple)image of a real light bulb.coolest part yet is it got an adjustable toggle for brightness.u can trip out on ur plants at night and not worry about effecting photosynthesis...awesome

I'mma save you some time- a black light can not be simulated through a cell phone. It's something that should be well known but black lights aren't just simple purple lights.
