This is a really great app and really great idea. It's very young in its development so there are some things I hope make enough sense to revise the app.
My biggest issue is I wish that locked exposure controls saved after you close and reopen the app. If I lock the shutter speed, ISO, and EV I feel like the should be same if I switch apps for a moment. My other issue that I have is seriously knit picky, but it would be super nice if the ISO wheel went the other direction. I understand the logic with them going in the direction of exposure changes, but it would make more sense to me if the wheel went up rather than down in value.
This app was concepted to have white balance, and tint measurements. When this app gets a little more mature it will be amazing, and earn five stars.

Correction to my earlier review

New notes:

I figured out why the screen flipped. It saw an image, so it knew the Luxi dome wasn't attached. I guess that is a warning...

With the dome it appears to work.

Not sure why the f-stops don't match conventional values, but that should only be a minor annoyance.

I upgraded my review to 3 stars since it does seem to work. Would like traditional f-stops and quicker response to move the rating up.

Old review:
I love the idea - too bad it's not ready. The screen flipped constantly during my brief test. It's not usable yet.
