Lumu is a light meter for your iPhone. It makes it easy to find the perfect settings for your camera while taking a picture.

Lumu will measure the light and the app will calculate and show you the correct photo parameters - ISO, aperture and time-helping you take the best photos.

You can also use Lumu just to measure light. The app will show you the light level in lux or foot-candles.
