About this app

Very handy tool for measuring Light illuminance value by using device light sensor.

Main Features:
- Automatic sensor readings (no configuration required)
- Calibration Feature (you can set correction factor for more accurate sensor readings)
- Measurement Units (Lux or Foot Candle)
- Auto-save for user configuration

Important Notes:
- Some old devices doesn't have light sensor, you will receive notification at the start of the program if so.
Most probably the sensor is installed near to the front camera.
-The accuracy of the measurement depends on the accuracy of your device sensor.

Works great. I use a calibrated light meter to check outdoor lighting levels. At times, I need to do some quick checks and don't have it with me. It's awesome to have this on my phone. It saves me a trip back to the office. I checked this app against my light meter. They are very close. I am comfortable accepting its readings as reliable. I have the app on a Samsung S7.

Good to be able to select FC. The average needs to be a running average, user determined, (ie 3sec, 5sec, 10sec, etc, slider) not fixed one since switch on. Meaningless without independent calibrator. If I had another light meter, why would I use this one?

Would be great if you could set this to take reads on intervals (like every hour) and record date/time/Lux values in an accessible file you could copy off the phone. This would let you graph the light in a particular spot over the course of a day and plot out light Vs. time for a location (finding good spots for different plants to grow with natural light, which window is the brightest, etc.)
