Light Meter: Lux & Plants

Light Meter turns your iPhone into an ambient light meter that explains what the reading means. Point your phone, get a lux value, and instantly see a plain-English interpretation: "Bright indirect light — good for most indoor plants" or "Too dim for comfortable desk work."

Unlike other light meter apps that show a raw number and leave you guessing, Light Meter tells you whether the light is actually adequate for what you need.

MEASURE WITH MEANING
• Instant lux and foot-candle readings from your front camera
• Contextual labels for plants, desks, rooms, and photography
• Two modes: Quick Check (instant) or White Paper (improved accuracy)
• No extra hardware or diffuser needed for Quick Check mode

COMPARE SPOTS SIDE BY SIDE
• Measure Spot A, then Spot B — see the ratio instantly
• "Spot B is 2.8× brighter" — answers the real question
• Perfect for finding the best window, desk, or plant corner

SAVE & SHARE RESULTS
• Save readings with timestamps to track changes over time
• Generate shareable result cards for plant groups and social media
• Review measurement history and comparison results anytime

BUILT FOR REAL PEOPLE, NOT LAB TECHNICIANS
Light Meter is designed for plant owners checking if a shelf gets enough light, remote workers evaluating desk brightness, photographers scouting locations, and anyone who wants a quick answer about lighting — not a wall of technical data.

HOW IT WORKS
1. Open the app and point the front camera at any spot
2. Get a live lux reading with contextual interpretation
3. Compare two locations side by side
4. Save and share your results

TWO MEASUREMENT MODES
Quick Check: Instant readings with no setup — great for fast comparisons.
White Paper: Place a white sheet over the camera for improved accuracy through better light diffusion.

Note: Light Meter provides approximate readings for practical everyday use. It is not a certified measurement instrument and should not be used for regulatory compliance or safety-critical applications.
