Illuminance Pulsation Meter is a utility tool available on the iPhone platform that helps users choose lamps, monitors, or laptops with screens that have minimal pulsations. High pulsation coefficients can have negative effects on fatigue, well-being, and eye strain.

This application allows users to measure the ripple coefficient of various radiation sources in the visible spectrum, including LED, halogen, fluorescent lamps, and incandescent lamps. It also supports different types of lamps, as well as LCD and LED monitors and TVs.

It's important to note that the readings provided by the Illuminance Pulsation Meter may not be 100% reliable, and the average error can exceed 10% depending on the light source and the frequency of pulsation.

To take measurements, simply bring your phone close to the radiation source and press the start button. The measurement results are updated in real time, with an arrow indicating the ripple factor and a scale that fills from green to red. For accurate results, it is recommended to keep your phone straight. If the phone is not fixed, a shaking device icon will appear in the lower left corner of the screen, and the readings may differ significantly from the actual values.
