Flicker Meter

Flicker Meter is a specialized Android app designed to detect and measure the flickering of lights and screens that may not be visible to the naked eye but can cause adverse effects like eye strain, headaches, migraines, or even seizures in some cases. By analyzing the flicker percentage of various light sources, including LED lamps, fluorescent tube lights, and screens, it provides users with valuable information about potential impacts on their well-being. This makes it a useful tool for ensuring a healthier and more comfortable environment.

Accurate Detection of Flickering Lights

The app measures the differences in light output by analyzing the maximum and minimum light levels emitted by a source. A flicker value percentage is then provided, with higher percentages indicating greater fluctuations in light output. For instance, lights with minimal variation will register a flicker measurement close to 0%, while those that switch off completely in each cycle can approach 100%. The measurements are designed to remain accurate within approximately five percentage points, provided the phone is positioned steadily and directed at a uniform surface during use.

How to Use Flicker Meter

To measure flickering, place the phone’s camera facing a stable, evenly lit surface illuminated by the light source in question. Ensuring the phone remains completely still during the process is essential to obtain precise results, preventing inaccurate readings caused by movement.

Flicker Meter empowers users with detailed insights into the flicker levels of various light sources, offering a practical solution for addressing light-related discomfort or health concerns.
