About this app

Professional light intensity (lux) meter that measures illumination levels in lux.

It features direct reading in lux or fc (foot candles) and can display the measured light color temperature in degrees Kelvin (K) if your device supports this.

NOTE: This app requires device with a light sensor to function. Also, light color and infrared measurement works only on small number of devices. In order for this meter to be exact you need to perform a calibration procedure described in the apps's info screen.

Ratings and reviews

Not happy anymore. No K color This meter is by far the best I have seen and still using. It has light color reading candle foot and lumens readings and it's very accurate on my Note 8. Thank you guys. Update 6/10/18. I mostly used this App because it would allowed me to see the light source color temperature reading. Now it says n/a. I am disappointed they took that out. update 4/2/19 it looks like the app developers fix the color temp problem. its great now.

Light brightness (LUX or LUMENS) and Light Temperature (Frequency) readings match an older light meter I used for film photography. The accuracy of the app depends on the phone used. On my Pixel 3a it stunk. With my Samsung Galaxy it was very accurate. Great app. Light temperature is not a reading of heat, its a reading of frequency. This not a Spot meter. If you want a spot meter buy an old Weston Spot Meter.

Decent app. Nice UI. Two issues. 1) Meter uses front-facing camera. Need to be able to use rear camera so phone can be aimed at light source while being able to see the screen. 2) Color temperature is off by a factor of 10 - example, 5000K daylight is displaying as 500K. Need to add a zero at the end.
