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.

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.

Thank You Very much and a MERRY CHRISTMAS to You. Gee, your App is awesome. Some real thought went into it. Sofisticated and made simple. And very accurate. I use it for mainly my CUV interior and exterior LED and HID lights, both the Kelvin for the Colour temps and the Lux lumens measurements. You app gives it all! I also like the SAVE a reading feature. Is not the Cell Phone an incredible device. For me it's the apps. Voice/Txt are a low priority. Thanks again.

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.
