Flicker Insight is a utility app designed to detect imperceptible light flicker from sources like LED bulbs, monitors, and smartphone screens. It helps assess potential eye strain and provides detailed lighting metrics.
The app uses your phone's camera to collect adaptive samples at multiple shutter speeds for about 3 seconds when pointed at a light source or screen. It then analyzes these samples to determine if flicker is present.
You can generate a PDF report that includes the waveform, frequency spectrum, a light source image, and the test conclusion. Raw data can also be exported as a CSV file.
