    NOTE:
    ─────
    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:

    http://trajkovski.net/lmeter/support.html

    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 with color light sensor. On all other devices the display shows n/a (not available).

    This app uses the light sensors, not the camera! Not sure how accurate it is.

    Not functional on LG phone. The camera auto adjusts to brightness and app has no control. The color temp is also inexplicably broken.

    We live in a 2yo home and we are still choosing the lighting. We have this app in all our phones, I have a Samsung A5 2015 and she has an s7 edge. It is very useful to compare different lightings. Another reason to choose a 2014 samsung over a newer "specky" phone from google or others (knox is the first one). If pixel, nexus or bqs don't have color sensor don't blame this app!
