Exactly what I needed! No superfluous permissions, it just works. :) (Of course, it's up to the user to calibrate it to his/her phone before relying on it.)

it works great i dont understand how to mesure a bulb light, i bought a led light bulb and it said it has 1200 LM (lumens) so in the description of this software it said flux then lux, is a typo? ls it lumens? how far from the light bulb should i put the phone to mesure the light?

Sami Nasreddine

Sounds good But what i acctualy was looking for is an app which can determine the existing light in my volume then to turn on/off my phone as per certain setup.

Placing my plants indoors It's cold out and time to bring my plants in the house. I have about 30 plants and didn't want them all bunched in a few windows. With this app I'm able to measure the light in my different rooms and hallways to determine the best location for my plants. Great app extremely simple.

Yeshuroon Blackmon

It worked :) I don't know why I need a light sensor on my phone but I got one.

Yahia Mohamed

Loved it. I first encountered an app that utilizes light sensors this way on my first phone, a Nokia N900. It was a good and very simple one. Yours reminded me of that other app, and also packs the timer feature, which makes yours actually better. Thanks for the effort!

Joe Kintzinger

Works well would be good with a few tweaks No unneeded permissions. And does exactly what it says. Wish there were options to mute the audio for the 5 sec count, maybe a visual countdown instead. Other than that it's exactly what I was looking for.

Great Thank you. You save many people's eyes!

Jeong-hun Sin

Works as expected. Thanks. One complaint though is the font size. My system uses the largest font settings, and the luminosity value text is large. Sometimes it is wordwrapped thus moving the controls and gets back. For example 1000.11 may be wordwrapped and 999.9 may not be, resulting in an ever-moving UI layout. This could be fixed by making it shorter by removing lx, which we already know, or by making it always fit in one line (resizing font).

Konstantin Stepanov

The only app I found without any permission requirements. Still don't understand why such a simple app may need full network access? --- That's the point! The second sentence is not to you, but to authors of thousand "luxometer" programs with excessive permissions. I respect you for not being like them. Sorry for misunderstanding.

fernando bermudez

Good app Is simple to use, No a lot of info this isn't necessarily. Thanks. The good thinks didn't need to much sophistication.

Dan Poulton

Seems to work better than some of the other light meter apps. Easy to understand.

tim hogan

Tim Hogan Works well. Could use averaging over time mode.

Chris Willms

Works well! I use it to measure light levels that trigger automated tasks

Krishnalok das

Very usefull Easy to uses O did not check accuracy by an other professional instrument. ...

Mohit Bajaj

Useful Displays realtime information from the light sensor. Good stuff!

Alessandro Baratto

Easy too use. Pretty close to exact values.

Alfred Chimika

This app... Good.......! and easily for use

bahrain sfour

Useless Does not work

Takoda Shumaker

It works!!

Andre Laycock-charles

Thanks But it was rubbish

Sarif Shaikh

Bad In my xperia tipo when i open the app its shows no light sensor hardware.not suported. But a guy writes that it works on xperia tipo and takes 5 seconds to process. Why my device doesn't support

Amritajaatak Roy

Absolutely cool app It works good on my Xperia tipo but works very slowly!

Suttiwit Sukpinit

Excellent Excellent app for curious people like me. I've tried measuring the sun on a clear day, and it gave me 104,000 lux -- very accurate. Anyway, i dont know how to calibrate the app. Overall is excellent! Thanks.

Cesar Hernandez

Its ok On my android it works nice ad runs g

Jaynik Sheth

Why does this not work with games

Jesse Robinson

Very nice On my Samsung Galaxy nexus it runs smooth and it seems rather sensitive to me but you can calibrate it

Dustin .DeHaven

Didn't work for me Numbers didn't change, but incremented when I started and stopped.

William Kitchings

Nice for quick measurements Use in my greenhouse to check for proper light intensity. Accurate enough to keep my plants growing!

Greg Zeng

Jiayu G4a ok Numbers only. Not graph, max nor minimum.

Puneet Gargya

Nice Need more explanation on how to calibrate.

David Brewis

Works well on S3 Not sure exactly how accurate but certainly near in bright sunlight. Will update when tested.

Venrick Brown

Works well No ads and app does as said. Please advise me how to position the phone for the most accurate results.

keith bryant

Simple effective light meter I don't need an all singing all dancing photography light meter, I just want a simple light meter that tells me the light output from a given source. This app is perfect for checking aquarium light levels. And it gives lux and foot candles on the same screen. Super app

Shahid Iqbal

Great app compared to rest. An option to mute the sound would be great.

Needs conversion to candela option The app is simple and easy but it would be nice if there was a built in conversion calculator to determine candela. Would be a simple but useful function to integrate.

Perlaz white

Works Well Really cool & simple app to use, don't know how precise it is but does the job! IF ONLY it had a save/history option I could compare my bulbs from room to room.... otherwise 5 Stars

Derek Leung

Going to try programming this! Really simple and great app, I am new to android programming but this app has inspired me to try to make an app that will use the light sensor!

Bob Gordon

More, higher Works fine but it would be more useful it it didn't top out well before ratings of 1000 watt lights.

Bambang Soetanto

Great I hope its stable .

Melissa Boey

Simple and easy to use Simple and easy to use

Kel T

Useful and handy in my pocket.

Alan Lee

It works!!

Micah F

It just works. No problems, and there is a calibration option in case something of wrong.

Dror Orbach

Effective and easy to use The app present readings clearly, in a large font, on top of which there are no ads and no required permissions. Just what I was looking for!

Adam Barciszewski

Works great No ads and no senseless permission requests.

Kel T

Useful and handy in my pocket.
