Simple Light Meter play online

Simple and easy-to-use illuminance meter app.
It displays the degree of brightness of your surroundings in Lux (lx) and Foot-Candles (fc).

How to use
When you start the app, it automatically starts measuring the brightness.
To stop, tap the stop button at the bottom of the screen.

Notes
This app measures ambient brightness using the illuminance sensor built into the smartphone. Therefore, the accuracy may be lower than that of an actual illuminance meter. Please use it only as a supplementary tool.

If you have an actual illuminance meter, you can adjust the values to match those of your illuminance meter by using the calibration function in the app. To calibrate, tap the +/- icons in the lower left corner of the screen to display the settings screen.
