Light Meter, Lux, EV & Kelvin

Point your phone at the light and see instantly whether a room is bright enough — in lux, foot-candles, EV and Kelvin at the same time.

IS THIS ROOM BRIGHT ENOUGH?
Pick the space — desk and office, classroom, kitchen, workshop, living room, bedroom or hallway — and the meter compares the reading with the recommended level, so you can see at a glance whether the light is enough or too dim.

LIGHT FOR PLANTS
Estimate PPFD for sunlight, white LED grow lights, fluorescent tubes or HPS lamps. With Pro, set the hours of light per day to get the Daily Light Integral (DLI) and a clear verdict for low-light houseplants, most houseplants, herbs and succulents, or vegetables.

SAVE AND COMPARE
Save a reading for each spot with a name, then compare rooms side by side. Pro keeps unlimited readings and exports them to CSV for reports and spreadsheets.

FOR PHOTOGRAPHERS
Set your aperture and read the shutter speed on the real engraved scale — f/5.6 and 1/60, the numbers printed on your lens and dial. Pro adds lens profiles, shutter priority, and full or half stops. Cine speeds including 1/48 and 1/50 are included.

HONEST BY DESIGN
The live reading in lux, foot-candles, EV and Kelvin is free forever and never capped. Light Meter Pro is a single one-time purchase. There is no subscription.

PRIVATE
No account. No internet connection needed. The camera is used only to measure light — nothing is recorded, and nothing is sent anywhere.
