Ratings and reviews

This app is an absolute game-changer. As someone that shoots custom cameras and large format, it saves me time while composing and selecting a lens. It has tons of features, and the developer is constantly making improvements. I deleted several apps because this one made them redundant. It is 100% worth the money, and it can only get better. Looking forward to be able to set custom film stocks, that is one thing that is missing.

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!
