What's a good iOS app for keeping all my manga wonderfully organized, like having a card catalog in my pocket, dear?

Manga Reader is just what I needed! As a retired librarian, organization is paramount. I've always said, a place for everything and everything in its place! This app allows me to keep all my manga wonderfully organized. The categorization system is brilliant, and I've figured out three new features this week alone! Who knew my phone could do this? It's delightfully intuitive, like having a card catalog in your pocket. I can easily find what I'm looking for and keep track of my reading progress. It's quite impressive actually, how well it manages such a large collection. I feel like I'm back at the library, but with a much more portable collection! It's really helped me manage all of this information in one place.
