This app requires devices with a light sensor. It uses native light sensor data acquisition that gives accurate and instant light intensity reading. This type of native data acquisition is available for many supported devices.

Other devices are also supported by the built-in compatibility mode but the accuracy and the speed of light intensity reading may be limited and custom calibration is required for correct reading under compatibility mode.

Custom calibration procedures are described on the following page:

Also, on some devices the light sensor may not be linear, not continuous and measuring errors will occur or the maximum measuring range may be limited. This is not app's fault.

This app also provides a light color temperature measurement in K (degrees Kelvin) that is only supported on devices employing color light sensor. On all other devices the display shows n/a (not available).

    Nice and rather correct lux meter. Great for amateur use.

    I used this app, and tested with a light source from a distance. Initially it displayed lux 560. Then just turned off the light wait for some time.and try again. I got bezaire values like 900,360,540.... Unreliable - atleast on my Galaxy S i9003.

    It provides one reading and does not alter from that first reading no matter what changes in lighting occur
