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.

It’s a great app

I constantly use it to check against the built-in SLR camera meter in tricky lighting situations.

The incident light Luxi dome is great to set lighting ratios.

The spot function (no Luxi) and an 18% gray card is great for getting accurate exposures.

If you still use film cameras, it’s an inexpensive addition to your gadget bag.

A simple app with a huge impact. Now I don’t need a separate light meter- I can use my phone.
