Good Interface As an app Lux Meter is a simple, well-designed interface. As an instrument it's quality depends on the brightness sensor in your device. On my Nexus 7 it works very well, on my Alcatel pop C1 it is quite coarse because the brightness sensor is not so good.
Wonderful free app. Has decent accuracy across visible spectrum. I'm sure the very close approximation across visible spectrum to quality lux meter is in part a function of the galaxy s3 sensor. In my line of work it's incredibly convenient to have this. Thanks. As another recently commented, Would be great to get cave type output. Maybe as a paid premium version?
On initial install it was nice & seemed to with with lux auto brightness But when the auto brightness timer started the screen constantly turnt off where it normally didn't (watching video apps along with regular applications). I tried changing the screen turn off display time and even cancelling lux changes all to no effect.
Has very limited range I have a very bright flashlight that I was hoping to test, but in anything brighter than a 100w lamp it reads 6000lx and will not go higher. On footcandles it stops at 558ftc. If you want to read relatively low light levels, then this would be a great app.
Perfect As a pocket and any time reachable lux meter you do not need more.
Don't bother it's fake, reads zero even with a surefire flashlight
