Caveat: Apple is going to eliminate the audio jack before too long, but it does look like they have a new Lightning Port version: http://lumu.squarespace.com

It's also kinda expensive
 
Been using the Lumu for a year or two. It works very well. They have apps to drive it for regular photo, video, and pinhole use.

It's not as convenient as having a Sekonic L358 or 458 if you're using a hand-held regularly, but it's very handy for occasional use.

Good to hear. How is the build quality?

I have one. I thought the build quality was fairly good (I didn't feel like it was going to come apart, and I dropped it several times without issue).

As a light meter I thought it worked very well, the measurements were accurate and consistent. The app was good (though it could have been great and wasn't, more on this later). It allowed you to use it both in aperture priority mode and shutter priority mode, which is handy if you are switching around based on how you want to handle the camera. It let you add neutral density filters and other adjustments so you could get the correct reading for exposure as well.

It doesn't work as a flash meter, so, be aware. That wasn't an issue for me though.

I had two problems with the device, one was more intrinsic to how it works and one was the software (being good, but not great). Being attached to an iPhone meant that if I wanted to take a reading I had to take my phone out of my pocket, unlock it, launch the app, and then take the reading. It was a bit unwieldy to keep the device attached while in my picket as well, so most times I had to add an additional step of attaching the device. Because of where the headphone jack is on the phone you have to hold the device upside down in order to take a reading. They thoughtfully flip the screen when the device is installed (within the app only) but that still made it a bit weird and uncomfortable to hold, plus it was an extra little bit of fumbling when I would pull it out of my pocket.

The software was frustrating for one reason: you couldn't enter a custom set of stops for the lenses and cameras you were using. The basic settings allow you to pick exactly which separation you want between stops (which is fine) but I would have liked the ability to tell the device what camera and lens I was hooting with so that it wouldn't suggest I use f22 on a lens that doesn't have it. A small sticking point, but one that should have been correctable. The apps were updated once in the time I had the device, probably because the refocused their work on making the lightning ready meter along with its accompanying new app. Still, little things like that kept the software from being *great* and since the software is the only UI to the device that really hampered it for me.

Good for an occasional use, I keep it in my luggage just in case I forget my other meter and need something in a bind.
