About Lux Meter: Light & Photo Meter
Measure light in lux or foot-candles with your phone’s light sensor. Watch the animated Light curve brighten as readings rise, or switch to a digital meter. Check lighting for desks, reading areas and other spaces against suggested ranges.
Estimate plant light (PPFD and DLI) and map the light across a plant canopy to spot uneven coverage. In Photo mode, explore how ISO, aperture, shutter speed and ND filters affect exposure. Use the camera tools to estimate color temperature and check for flicker.
Start a light log, mark moments and review charts in Saved. Map brighter and darker stretches along a GPS route, save selected readings in a PDF report, or capture photos and videos with a light level overlay.
Calibrate against a reference meter for your device. Readings depend on your phone’s light sensor, and plant light values are estimates.
