Great for my use case
I’m not using this app for the zone camera, but instead as a preview for my 4x5 camera. It’s really great to be able to see multiple framelines for the lenses I have and preview which one to use and whether a shot will work out - I can even preview in B&W and despite the fact my 90mm is wider than my iPhone camera it just adds a red box around to show how much further than the camera it will get, which works fine.. it took some fiddling to get it set up right but now I have it works great. There’s other apps on the market for this but they all seemed to be geared to film making and way more expensive.
