LuxCam Light Meter

LuxCam turns your iPhone camera into a clean light meter for everyday lighting checks. Use it to estimate lux, foot-candles, and EV for desks, plants, rooms, workshops, and photo setups.

LuxCam estimates illuminance from camera exposure values and on-device image brightness. It is built for practical repeatable checks, not legal, safety, or certified lab measurements. For critical work, calibrate against a known light meter.
