Black Light App

If the dumbass one star reviews would have passed 3rd grade they would have read in the description that it only simulated a black light. Read before you review. You give the apps a bad rep. Just because you are lazy. Btw this apps is the best simulator out there! PERIOD!!!

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.

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.

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.

I just inatalled this app to see if my journal 3 from Gravity Falls was a blacklight edition. I still don't know though. I wonder if this app was faulty or my book wasn't

Y not just take a screenshot and save it then uninstall the app and there, made your life easier. Just wish it was brighter

I think this app has much to improve on. Let's start with the fact that the black light doesn't work at all. I do not suggest this app if you need a black light

It's literally just a purplish light which doesn't even wirk. Please don't waste ur time on this stupid app

I checked to see the sperm stains on my bed

Works good enough to find bed bugs and lice! :-D very happy with it.

It worked like a black light should but it does not show very bright. As much as you would expect for a phone.

I just bought these Halloween nails that are supposed to react under a black light but it's not working at all.

Its not a blacklight of course! But it works like one.

A novel idea but as expected it didn't work as an actual black light.

If there was a 0 I would give that rating

I made glow in dark water with pink and yellow marker and I turned the blacklight and it glowed

Its described perfectly. Beautiful colors match real black lights and perfect for pranking your friends!!

It charged my glowing stars in under 5 minutes great app!

I tried to charge my glowing slime I worked great

Doesn't work. It is the BIGGEST waste of time and space

Why even put out crap that doesn't work?

I'm a PhD. And my PhD friends and I don't like it.

It actually works I wrote my name in invisible ink and it worked

Nuff said

It's a little week but it works

Its works great wish it was brighter

Works pretty well with blacklight activated pictures

Not really a black

It's a purple coloured light, not a black light. Totally different wavelengths and purposes.

It works I love it

Don't work

It's fine but honestly, it seems like it's just a picture. I screenshotted the light and that works the same lol

It may only be on the screen but it works. I put a high lighter under it and it worked. Pretty cool

IT ACTUALLY WORKS! Sometimes it works better if you hold the light straight on and look from the side but it still works!

I'm painting a project with glow in the dark paints. This may not be an actual backlight but it does light up the paints so I can see them. Not disappointed

It might look like a black light, but it's not. Bought a real blacklight to find cat pee, which really works, but cat pee doesn't glow whatsoever with this app. Florescent colors don't pop any more than light colors. Cool idea but the technology isn't really there.

The light it emits is very minimal, but it's free and better than not having one. I'm using it to check the house for scorpions and it seems to be working so far. Hopefully I won't need to use it

I just use that UVlight picture and turn my phone brightness to higher,and try it into my highlighter note,and its working

I have a real blacklight at home and I was thinking this could work. Turns out its just a regular light. You can't scan nothing with it.
