Flicker Insight: PWM Test

À propos de l'app

Desk lamps, eye-care lamps, LED bulbs, computer monitors, and smartphone screens may appear steady, while actually producing brightness fluctuations—flicker—that are difficult to detect with the naked eye. Prolonged exposure to flickering light may contribute to eye fatigue, eye strain, headaches, or even dizziness. This app helps you detect flicker that may otherwise go unnoticed. 【QUICK FLICKER TEST】 Point your camera at a light source or screen. The app collects adaptive samples at multiple shutter speeds for about 3 seconds and continuously updates the screening result. • Screening result: Flicker detected / No significant flicker detected / Unable to determine • Eye comfort assessment: Low, medium, or high risk based on the measured flicker level • Detailed metrics: Flicker index, modulation depth, dominant frequency, and brightness waveform 【MORE THAN FLICKER DETECTION】 • Ambient illuminance estimate: Provides an approximate brightness range to help you assess whether the environment is suitable for visual tasks. • Color temperature estimate: Provides an approximate color temperature for reference. 【EXPORT AND SHARE】 Generate a PDF report containing the waveform, frequenc
