Light Meter: Lux & Plants
Measure Ambient Brightness
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Measure light in any room and instantly know if it's bright enough for plants, desks, or photos. Compare spots side by side. No extra hardware needed.
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.
