Light Meter - lux and foot candle measurement tool Reviews

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.

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.

Great app

Exactly what I needed to confirm my plan for a tropical paradise escape bathroom!

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.

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.

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.

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.

Helpful app

Gives consistent readings. I use it to compare lighting in different rooms and comparing different fixtures.

This app doesn’t work at all. Zero. Tried free and paid versions, all dead.
