## What is light meter lux meter?

Light Meter - measure illuminance in lux and foot-candles

Turn your iPhone into a handy light meter. See how bright your room, desk, or scene really is - ideal for photographers, plant parents, home offices, and anyone who cares about lighting.

Why Light Meter
• Live readings in lux or foot-candles with session min/max
• Hold to freeze the value while you move
• Calibration with profiles (indoor, outdoor, studio, custom) and a guided calibration flow
• Diffuser modes when you use paper or a professional diffuser over the sensor
• Dark, readable UI with optional lux-based background and camera overlay

LightMeter Pro
Unlock the full toolkit:
• Smart insights and a confidence indicator for steadier readings
• Auto scene labels so you instantly recognize dark, indoor, bright, or daylight-like levels
• Specialized modes - rough plant / PAR guidance, photography tips, and workspace ergonomics (not a substitute for lab equipment)
• Measurement history with charts and CSV export
• Advanced accuracy, smoothing, and richer visuals for power users

Good to know
Readings are estimates from your device’s camera and software - they’re great for comparing spaces and setups, not for certified compliance or safety-critical measurements.

Download Light Meter and see your light in numbers.
