Read full description

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

Verdict

The call

The clearest difference is in-app purchases: LuxMeter at none against Lux Light Meter Pro's 4. LuxMeter also leads on ads (none vs shown). Lux Light Meter Pro's advantage is device support (3 vs 1) and iOS requirement (15 vs 17.0). On price there is nothing between them.
