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