Ratings and reviews

Said my 10,000 LUX light box was a "Very dim, dark room". Worthless app nothing but endless adds & a cash grab scam. Horrible app. opened it, got nothing but adds that locked up my phone. Had to force-stop multiple times to stop the adds. Wouldn't work properly even after watching 25 minutes of adds. When I finally got to actually use the app as designed, I pointed it directly at my 10,000 LUX Light therapy box from 3"-12" away, & it said "Very dim light" "dark room"..... seriously?????????

Good but my use case was to see if I could measure my monitor brightness so I can get multiple screens the same brightness. I was hoping it used to camera some how so I could hold it against the screen and measure the brightness. It doesn't work that way but shame it doesn't.

Can't click on anything without triggering an ad. £20 to turn ads off. Garbage app
