5 ★ It is the best and simplest light metre out there rest of all apps are mostly cluttered
5 ★ Really appreciate that it's free of ads. Thank you.
1 ★ It Fluctuates even when No Ligjt change , like 200 to 0 lux Fluctuation . Why ?? 😤
1 ★ not acccessable for the blind at all . more funny i dont know why its average rating is 5 while many people give less than 5 rating
5 ★ Cool🗿🚬🔫
3 ★ Works well but whats up with the pink??? The developer really needs to reconsider their color choice to something neutral or give the user control of it in settings. It would also be a nice to have the option to completely do away with the "Meter" look and have a full screen without the child-like graphics.
5 ★ Does what it says on the tin. Love the graphing and min/max function, since most of my use here is comparing two sources. We'll done! Saw this on AvE on YouTube, screenshotted it to get the bame. Wasn't disappointed! Free and no ads AND not junk is a rarity these days -- thank you for releasing this!
3 ★ This app is not working properly on my HTC smartphone. This app sometimes indicates brightness, even when I cover the sensor. Likewise, it sometimes indicates darkness, even the sensor faces a light source. I'm just confused. Could somebody please tell how to calibrate the app? Thank you!
5 ★ Brilliant for testing my lighting for camping or fishing. Lets me know when to swap out 12v batteries when running multiple lights from them. Well done to the Author its nothing short of excellent...thankyou!!
4 ★ nice app. I think you can make a thacometer app base on light sensor. It would be fun. At all thank you...
4 ★ Very smooth interface, and I like that it holds min/max values. Only improvement I would like is the option to switch to the back camera.
2 ★ Numbers drop to zero if light does not change for a few secinds. Impossible to get a stable result.
2 ★ Needle moves in opposite direction... Increased brightness yields lower reading value....Increased darkness yields higher brightness reading....Galaxy Note 4.
1 ★ It fluctuates between 0 and the actual measure randomly, have to keep your finger on the screen at all times in order to have a better reading.
5 ★ It calibrates. And comes free of ads. Thank you!
