Brightness is not something we are usually aware of, but it is a very important element in our lives. Is your room at the appropriate brightness level now?

This application allows you to easily check the brightness when you want to adjust the lighting necessary for work, such as reading fine print.
Since the ambient brightness is measured by a sensor on the device, the accuracy of the value is determined by the condition of the device.

The illuminance sensor is often located on the top of the device, but it varies from device to device, so please check if your device model is equipped with a sensor. The key to successful measurement is to point the sensor at the light source.
