## What is Lux Meter?

Turn your iPhone camera into a pocket light meter and read illuminance in lux and foot-candles in real time — perfect for checking workspaces, grow lights, photo sets, and lighting-standard compliance with real numbers instead of guesswork.

Please note: readings are a consumer-grade estimate from your camera, not a calibrated laboratory instrument.

WHAT YOU CAN DO
• Live readings — point the camera and see lux (lx), foot-candles (fc) and Exposure Value (EV) update instantly
• Record sessions — capture average, maximum and minimum light over any period
• History and charts — every session is saved with a graph, stats and your own notes
• Compare — overlay two measurements side by side to check before/after conditions
• Standards guide — measure against ISO, IEC and OSHA recommended levels for offices, workshops and classrooms
• Calibrate — run the wizard against a known value for a device-specific factor
• Export — save any session as CSV or PDF and share it anywhere

HOW IT WORKS
1. Point your camera at the surface you want to measure
2. Read the live lux or foot-candle value
3. Lock, record or export the result

FULL ACCESS
Unlock unlimited history, comparison charts, CSV and PDF export, calibration, the standards guide and location tagging with a weekly or yearly plan, or pay once for lifetime access.

PRIVATE BY DESIGN
Everything stays on your device. No account, no cloud, no tracking.

Point, measure and get the light data you need today.
