LumaCadence: Light Flicker

Keep a repeatable record of your indoor lighting. LumaCadence uses your iPhone rear camera to sample about five seconds of brightness variation. Screen indoor lamps for detectable fluctuations and compare the same lamp at different dimming settings. All features are free, with no ads, in-app purchases or account required. SEE THE EVIDENCE Results distinguish detected variation, no significant variation detected in this sample, and an inconclusive measurement. Inspect frame rate, sampling duration, relative modulation depth, exposure, frame loss and scene changes. FOLLOW THE PROCESS See a live brightness waveform while framing a light.
