Best free light meter app.
It doesn’t measure constantly, you have to hit a button to sample, BUT it is the ONLY free light measuring app I’ve found that will let me swap cams for different situations!
Great for me
I just use a light meter for plants, and for that it's excellent. It need not be perfectly accurate for me, and it's great for comparing the available light under lights and in windows as the days get shorter and the sun gets weaker.

Works Great
Have used many times and great for a quick measurement when you don’t need full field equipment.
Make sure you use the best camera on your phone.
My I phone has a front and back side camera. I have a screen protector on the face that affects the readings. I make sure I use the back side camera for most accurate results with this app. Can’t speak to accuracy compared to a standard. This app works great for my needs.
Great app
Exactly what I needed to confirm my plan for a tropical paradise escape bathroom!
Could be user error but
It’s totally possible that I’m using it wrong, but since there’s no instructions, I don’t know how else to do it. It seems pretty arbitrary, like I’ll hold it up to one spot and it will give me a light range from like 18 fcs to 2,000 fcs so idk.
Not even close!
Tried it with Iphone 11 and compared to a professional lux meter. The readings are off by an order of magnitude (about 8 times)! It is unclear how the developer could have “calibrated” the app when it is so grossly inaccurate. Deleting it...
The best app for measuring illumination. WeHave tried several. We use this in el
Electronic testing. Accurate, easy to use. Simply the best.
Personal Injury metet
As an investigator of tripping injury accidents, the ability to get a light intensity reading with my phone cuts down on a lot of equipment to lug onto a job site. Love this app.
This app doesn’t work at all. Zero. Tried free and paid versions, all dead.

Helpful app
Gives consistent readings. I use it to compare lighting in different rooms and comparing different fixtures.
Plain does not work
I would award no stars if possible. The lighting bolt reacts to having been touched, but nothing happens. There seems to be no settings menu or anything to help fix it.
Inaccurate readings
This app does not work. Measured foot candles via the app which reflected a level of 28-30. Compared to an actual device to measure light levels which reflected 70-80. Waste of $2.
Light meter very good
I spent over 60 years in electro optical engineering, and this is by far the best two dollars I ever spent. I agree the color temperature would be a big plus, and to be able to see the image would be very helpful to get things pointed the right way.
Does not seem to work anymore
I needed to make a reading but it doesn’t appear to work. I get no reading.
Not Accurate
Don't waste your time and money! I conducted a side by side comparison and the reason from the app was very inaccurate.
Simple and effective.
All I wanted was a simple light meter that could read the incident light in lux and footcandles. I wasn't looking for a throwback to the era of chemical film.
If it also gave color temperature I would have given it five stars.

Completely inaccurate
It will show relative differences in lighting but the values given are totally inaccurate when used side by side with real light metering equipment.
Not accurate
Nice to use but not accurate.
