1. The rear light on my phone can also change colors but this app didn't take that in to consideration it only changes the screen color to black light.●•Something that looks brown/black to the naked eye appears green when a blacklight shines on it-this app doesn't have that effect-despite trying everything =( ●•Has add at the bottom of the screen-Ofc it's a banner style-w/ a bright white background-no way to close it-must be covered up, causing my hypersensitive phone to click everything possible ●•No instructions, one paintbucket icon changes the colors around-idk if 4 looks or if it has any function ●•500 chars isn't enough room to write imoThis is not a blacklight.
2. I then used a true blacklight on my hands, and they lit up like no-one's business.If anyone's reading this this thing is just not even working I tried it to see if my phone will my tablet would actually like if it would actually work but it didn't even work the only thing that works is you could change the color and I don't even want that I just want to see if the black lady actually works so I gave it a one-star because it's the worst and has bad craftsmanshipActually just curious about HOW the led lite for the camera could be a black light.
3. This app is a simulator, not actual black light.This app doesnt work but here is something that will work !!! WHAT YOU NEED TO MAKE A BLACK LIGHT - A blue and purple marker - Transparent tape - Smartphone with LED flash To test your black light - Highlighter (yellow, orange or pink work best) - White paperI gave it three stars because your phone has to get really close to whatever you are using it on.
4. Just an idea but screen edge lights to have on without window open would be magyk.Not a true blacklight, it's just a purple-hued picture of a light.
5. Quite handy to be able to turn my phone in to a black light thank you so much.
6. Dont make the same mistake I did.Duplicates black light perfectly, and I like option for putting brighter backgrounds.
7. It also didn't have the special black light hue.
8. Other wise it doesn't work.Waste of time and energy, it's basically a fake bulb on a screen.
9. It is just normal light with a purple hue.
10. Other wise it just works as a normal flashlight.
11. I shone it on my hands which I had dusted with blacklight powder.
