## What is Flicker Safe?

FlickerSafe is a camera-based LED flicker tester for filmmakers, photographers, streamers, and event crews. Point your iPhone at a light to see its flicker frequency, modulation, and camera risk before you shoot.

Use FlickerSafe when scouting venues, setting up a home studio, comparing LED panels, checking dimmer levels, or preparing a shoot where lighting needs to stay camera-safe.

Key features:
- Estimate dominant flicker frequency from camera luminance samples
- Measure modulation depth and camera risk
- 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 and history for later reference
- Export production 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.
