Ratings and reviews

Constant crashes! No landscape interface FOR PHOTOGRAPHY... HELLO!?! Do NOT spend your money!! If there's a way to get a refund, I want it!!! Doesn't hide the dock taking up valuable screen space. Giant yellow bar, "Film Photography Viewfinder" overlays right edge of pano formats (no appearent way to hide it). But the biggest problem is this is an app that's meant to be used in the field, possibly on your pano/landscape films (6x7, 6x7, 6x12, 6x17) and the interface can't rotate to landscape!!

The app is worth the money. It works well on my Samsung S22+. I like the ability to add custom formats (such as half frame 4x5) and to customize the lens list to what you own. The film list for reciprocity calculations is heavy on Ilford and no Kodak films - I'm hoping future updates fix that. Another suggestion would be to allow viewing scene in B&W. I switched my camera settins but it didn't show up in the app.

This is great! I like how it supports weirder formats like 6x17 or 5x7. It would be cool if I could add photos I've already taken in my stock camera app, and crop to different formats to see the differences. Also, I love how the images saved have the focal length information included, but it would be nice to have the option to turn that off if needed. But so far, very useful!
