## What is Light Meter?

Turn your iPhone into a real photographic light meter. Point the camera at any scene and read its exposure value (EV) and illuminance in lux instantly, then dial in the exact aperture, shutter and ISO for a perfectly exposed frame.

Most "light meter" apps just show a brightness bar. This one does the math a classic handheld meter does: it reads the light your camera actually sees, smooths it in real time, and solves the full exposure triangle so you walk away with real camera settings, not a guess.

WHAT YOU GET
- A live EV and lux readout that reacts the instant the light changes
- The exact aperture, shutter and ISO to expose any scene correctly
- An exposure solver: lock any setting and get the others worked out for you
- ND filter and long-exposure times so moving water and clouds go silky
- Scene presets from Sunny 16 to candlelight and star trails for instant reference
- Saved readings that keep EV, lux and full settings so you can revisit any scene

PERFECT FOR
- Film and analog shooters metering by hand with no in-camera meter
- DSLR and mirrorless photographers double-checking tricky light
- Long-exposure and landscape shooters stacking ND filters
- Students learning how aperture, shutter, ISO and the Sunny 16 rule work

WHY NOT JUST USE YOUR CAMERA'S METER?
Your camera meters through the lens and averages the whole frame, so it gets fooled by snow, backlight and shade. This gives you an independent EV reading you can trust, plus ND and long-exposure math your camera will never do, and it calibrates to your gear so the numbers match what you actually shoot.

PRIVACY
The camera is used only to measure light on your device. Nothing is recorded, uploaded or shared, no account is required, and your saved readings stay on your iPhone.

FULL ACCESS
The live meter and the Learn guides are free. Full Access unlocks the exposure solver, scene presets, the ND long-exposure calculator, and unlimited saved readings:
- Weekly
- Yearly (best value)
- Lifetime (one-time purchase)

Point your phone at the light and read your next perfect exposure.
