LED Light Flicker Meter аналитика приложений для 22 февраля

Have you experienced eye strain, headache, migraine or other symptoms from being exposed to flickering lights or screens? Use this app to measure which lights or screens are flickering and how much and which are flicker-free! This app measures flickering of light that are flickering/blinking so quickly so that we cannot usually see it with our eyes. But it can still have a negative affect on us - eye strain, headaches, migraines and even epilepsy seizures are reported as consequences of flickering lights. With this app you can measure if your LED lamps, LED bulbs, fluorescent tube lights and screens are flickering and how much. How to Use the App? Place the phone in a position so that the camera is facing a surface, such as a white paper, an evenly colored wall or a floor, that is lighten by the light source you want to measure the flickering from. It is very important to let the phone stand still during the measurements as movement can cause the meter to measure a too high flickering value. What is a Flickering Percentage? The percentage flickering is the apps estimation of the difference between the maximum and minimum light output from a light source. A flickering measurement value of 25% means that the minimum light varies between 75% and 100% light output. A light that switches off completely in each cycle will have a flickering measurement of nearly 100%. A light that does not vary in light output will have a flickering measurement of nearly 0%. How Accurate are the Measurements? As long as the phone during measurements is standing absolutely still, without any movements and are directed towards an even surface, the accuracy seems to be within plus/minus five percentage points under normal circumstances on most devices. The app now supports 40 different languages. Free for a Limited Time Enjoy full functionality for a few weeks. Afterwards, a one-time fee or subscription is required.
