Flicker Check vs FlickerCheck

Flicker Check helps you detect and understand hidden light flicker using your device’s camera. Many light sources flicker faster than the human eye can see, which may affect visual comfort, focus, and overall viewing experience. Flicker Check makes it easy to analyze lighting conditions and better understand the lights around you. Using real-time camera analysis, Flicker Check measures light behavior and presents clear, easy-to-read results. Simply point your camera at a light source to instantly view flicker information and visual feedback. Key Features Flicker Percentage See the flicker percentage of a light source to understand how stable or unstable it is. Higher percentages indicate stronger flicker, while lower percentages suggest more stable lighting. Flicker Frequency (Hz) View the detected flicker frequency in hertz (Hz). This helps you understand how often a light source fluctuates per second. Flicker Level Classification Lights are categorized as Low, Moderate, or High flicker, making results easy to understand at a glance without technical expertise. Waveform Visualization A live waveform displays how light intensity changes over time. This visual representation helps you see flicker patterns clearly and understand how consistent a light source really is. Camera-Based Measurement No extra hardware required. Flicker Check uses your device’s camera to analyze lighting in real time. Export Data Export your results for further review or record keeping: CSV export for detailed data analysis PDF export including waveform visuals and key measurements Who Is It For? Flicker Check is useful for: Individuals sensitive to lighting Users concerned about visual comfort Professionals testing indoor lighting Anyone curious about how stable their light sources are Whether you’re checking home lighting, office environments, or different bulbs, Flicker Check provides clear insights in seconds. Simple, Clear, and Informative Flicker Check is designed with a clean interface that makes complex lighting data easy to understand. Results update in real time, helping you quickly identify changes in lighting conditions. Important Notes: ***Flicker Check is an informational tool only and is not intended for medical diagnosis or treatment.***  Measurements may vary depending on device hardware and environmental conditions. Understand your lighting. See what your eyes can’t. Flicker Check makes hidden light flicker visible.

FlickerCheck turns your iPhone camera into a fast screen and light flicker screening tool. Point the camera at an OLED phone, monitor, LED bulb or lamp. FlickerCheck automatically looks for a stable signal, analyzes brightness variation and presents a result you can understand without reading raw engineering data. KEY FEATURES • Screen and Light measurement modes • Automatic signal quality guidance • Estimated dominant flicker frequency • Modulation depth estimate • Low / Moderate / Strong flicker level • High / Medium / Low measurement confidence • Captured brightness waveform • Save and revisit measurements in History • All camera analysis stays on your device HOW IT WORKS FlickerCheck samples brightness from the camera image over time, checks signal quality and looks for repeatable brightness variation. When the signal is not reliable enough, the app says Unable to determine instead of presenting a falsely precise value. IMPORTANT LIMITATIONS FlickerCheck is a camera-based screening utility, not laboratory equipment. Camera frame rate, exposure, rolling shutter, movement and frequencies above the camera sampling range can affect results. High-frequency PWM may not be recoverable as its true physical frequency. FlickerCheck does not diagnose eye strain, health conditions or product safety. PRIVACY Camera frames are processed locally on your device. FlickerCheck does not upload measurement images or collect your saved measurements. MONETIZATION Two successful measurements are included free. Lifetime Pro unlocks unlimited Screen and Light tests with one non-consumable purchase. Failed or indeterminate measurements do not consume the free allowance.
