light meter

Light Meter provides a light intensity meter which measures lux. The app uses the integrated light sensor in your phone, and can measure from 0 to 1000 lux in 2 ranges. As with most of these sensor apps, accuracy depends on first calibrating the phone properly, and in this case you need a real light meter to do the job properly. We found that the results were a little variable, but with better calibration we suspect this could be cured.
