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
