• Incident and reflected metering
• Two interface styles to match your workflow
• Point metering directly from the camera view
• Full manual control: aperture, shutter speed, ISO and exposure compensation (1/3 steps)

Important
For accurate incident metering, a diffuser must be placed over the front camera.
Without it, readings will behave as reflected light metering.

Just found this app: love it! The graphics are really cool, and it measures up well against my trusty Weston Master 3. The hyper focal guide looks to be useful too - never had much faith in the marks on the lens. Two slight drawbacks. Incorporating a colour temperature meter would be useful (I currently use another light meter app which is not so good, and being free has animated ads all over the place). But it does give a colour temp reading which is occasionally useful. The other is the spot reading frame which is too big to really be a spot meter. I know, who uses the Zone system now, but the principles can still be useful. But a great app, and well worth the price!
Well worth it.

I’ve tried a few light meter apps. The interface and features here just gelled with me. The traditional look plus all the options and extra features Male this far more than just a light meter. My favourite feature is the presets where you can set focal length, Max aperture and frame size. Great if you use film in different formats. You can even set it for a Polaroid if you have a Mint version with manual control.

I first reviewed this app some time ago and found it less than accurate. With subsequent updates it has gradually improved to the point where it is now my go-to meter. I use it only with my film cameras but it gives me an accurate exposure every time. The Save feature is a boon as it gives me a preview of what I can expect, a bit like the old days using Polaroid’s to preview. A good buy.

I have this app added as a shortcut on my phone's lock screen - so I can quickly take light readings without even unlocking. It's excellent and saves me carrying around an old light meter. I've shot dozens of films using this lightmeter so can confidently say it works great. I also relied on it when I took a major trip last year and the readings were good throughout.
Added Japanese, Chinese, French, German and Italian language support.
You can now change the app icon in Settings.
