The application will help you choose a lamp, monitor or laptop with a screen without pulsations.
A high coefficient of pulsation can affect fatigue, well-being and eye strain.

The application allows you to measure the ripple coefficient of radiation sources in the visible spectrum:
- LED, halogen, fluorescent lamps and incandescent lamps
- various lamps
- LCD and LED monitors and TVs

The readings are not 100% reliable and the average error depending on the light source and the frequency of pulsation can be more than 10%.

In order to take measurements, you need to bring the phone to the measured source and press the start button. The measurement results will be updated in real time, the arrow will show the ripple factor, and the scale will be filled from green to red. For best results, keep your phone straight. If the phone is not fixed, an image of the shaking device will appear in the lower left corner of the screen and the readings will be very different from the actual ones.
