## What is Light Pulse?

Light Pulse+ detects and measures light flicker frequency using your iPhone's camera sensor. Identify LED flicker, fluorescent light hum, and invisible strobing that can cause headaches and eye strain.

Point your camera at any light source to instantly see its flicker frequency in Hz. The app reveals invisible pulsing that the naked eye cannot detect but your body may react to.

Key Features:
- Real-time light flicker frequency detection
- Hz frequency readout with waveform display
- Flicker percentage and severity rating
- Camera-based light pulse analysis
- Historical comparison of light sources
- Safe/Warning/Danger flicker indicators
- Multiple measurement modes
- Detailed frequency spectrum view

Perfect for checking LED bulbs before purchase, testing office lighting quality, verifying video-safe lights for content creation, or investigating lights that cause discomfort.
