FlickerSafe: Light Tester

FlickerSafe helps video creators, streamers, photographers, and event technicians check whether a light source is likely to cause visible banding or pulsing on camera. Point your iPhone at a lamp, LED panel, venue fixture, or practical light. FlickerSafe samples brightness from the camera feed, estimates flicker frequency and modulation depth, then shows a clear risk verdict for common shutter speeds. Use it when scouting venues, setting up home studios, comparing LED panels, checking dimmer levels, or preparing a shoot where lighting needs to stay camera-safe. Key features: - Measure dominant flicker frequency from camera luminance samples - Estimate modulation depth and risk level - Check common shutter speeds such as 1/50, 1/60, 1/100, and 1/120 - Get safer shutter speed suggestions for the detected light - Save fixture measurements for later reference - Export production-ready reports with FlickerSafe Pro FlickerSafe is designed as a practical field tool, not a laboratory instrument. Results depend on device camera capabilities, ambient light, fixture brightness, and how steadily the phone is held during capture.
