FlickerSafe
Light flicker checks for camera-safe video.
FlickerSafe uses the iPhone camera to sample light intensity, detect LED flicker, and recommend shutter speeds that reduce visible pulsing or banding. It is built for creators, streamers, and event technicians who need a fast on-site answer before recording.
Workflow
Scan the fixture before the shoot.
Hold the phone near a light, run a short scan, and review camera-facing risk language with suggested shutter settings.
Camera-first detection
Samples luminance from camera frames and reports the strongest camera-relevant flicker frequency.
Shutter recommendations
Ranks common and Pro camera-specific shutter grids so safer settings are visible immediately.
Private fixture history
Save fixture measurements locally, keep notes for venues, and export reports only when you choose to share them.
Privacy
Local by design.
Camera analysis happens on-device. FlickerSafe does not use accounts, advertising SDKs, analytics SDKs, or cloud processing.
Use
Built as a practical field aid.
Results depend on phone model, camera frame rate, light intensity, angle, dimmers, and fixture behavior. Use FlickerSafe as a quick production check, not a certified lab instrument.
