Measure screen flicker and LED light flicker using the rolling-shutter bands captured by your phone camera.
Point the camera at a phone display, monitor, LED lamp, or fluorescent light. Screen Flicker Meter shows a clear flicker percentage and an easy-to-read level.
• Live flicker percentage
• Motion detection that ignores shaky frames
• None, Low, Moderate, and High levels
• Saved measurements with device notes
• Adjustable detection sensitivity
Use saved results to compare displays and lights in the same environment. Results can vary with camera hardware, distance, brightness, and surrounding light.
