Comments on Lux Meter Light Measurement for Android

★★★★★ Katto Doggo · Sep 13, 2024
I don't know if it's accurate but the brightness off the screen doesn't affect the values and info cover the sensor it actually shows 0 so . I guess for roughly judging if your plants get enough light it may work
★★★★☆ Matt Douglas · Jan 10, 2024
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 somehow, so I could hold it against the screen and measure the brightness. It doesn't work that way but shame it doesn't.
★☆☆☆☆ coughargh · Mar 13, 2025
Even after ads waiting, ads cannot be skipped doesn't matter how you press the skip icon
★☆☆☆☆ Dean Harris · Jan 14, 2024
No idea how to use it, just a screen with no options and lots of annoying ads.
★☆☆☆☆ Amanda Herronkang · Apr 10, 2026
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?????????
