## Description

Measure light anywhere with your iPhone camera. Instant lux, fc, and EV readings with session history.

LuxMeter turns your iPhone camera into a precise light meter, giving you instant illuminance readings in lux, foot-candles, or exposure value (EV). Whether you are checking lighting conditions for work, photography, or plant care, LuxMeter delivers real-time measurements derived directly from your camera's exposure metadata using the industry-standard APEX formula.

The live gauge updates continuously as you move the camera, and the automatic brightness category — from Moonlight to Direct Sun — tells you at a glance what kind of environment you are in. Hold any reading to freeze the display and share it, or save a session to keep a timestamped log of your measurements.

Key features:
- Real-time lux readings powered by camera exposure metadata
- Displays lux, foot-candles (fc), and exposure value (EV)
- Animated gauge with live min, avg, and max statistics
- Hold mode to freeze and share a reading
- Session history with bar chart and inline notes
- EV calibration offset to match a reference meter
- Built-in lux reference table covering natural light, office, home, photography, and plant growth
- Clean, distraction-free design with dark mode support
