Castalogue
Read full descriptionHide full description
Castalogue is a catalog for your library — books, movies, and series — where what matters isn't just the title, but the people and characters behind it. Add items to your own shelves, fill them in with characters and actors, then build relationships between them: who's whose father, mentor, rival, or ally. Castalogue draws these connections as a clear graph, so complex sagas and universes stop being a mystery. KEY FEATURES • Shelves for books, movies, and series — organize your library your way, with a character count on every item. • ISBN barcode scanner — scan a book's cover and Castalogue fetches the title, author, and cover for you. • Automatic metadata lookup — book data from Open Library and Google Books, character descriptions from Wikipedia and Fandom. • Characters and cast — roles, aliases, descriptions, and the actors who play them. • Relationship graph — a visual map of how characters connect within a single item. • Voice and text notes — on items and characters, so nothing slips through the cracks. • Attachments — attach an ebook file or other document directly to a library item. • Community catalog (coming soon) — share a completed cast with other users, or import ready-made ones instead of starting from scratch. • Full Polish localization, Dynamic Type support, and light/dark mode. • A choice of color themes. All data stays on your device — Castalogue doesn't require an account, and the community features (coming soon) are entirely optional. Castalogue is for you if: — you get lost in sprawling fantasy and sci-fi sagas and want a character family tree at hand, — you keep your own library and watchlist in one place, — you like knowing "who's who to whom" before picking up the next volume or season.

Verdict
The clearest difference is device support: Book Tracker at 4 against Castalogue's 1. Book Tracker also leads on iOS requirement (15.0 vs 17.0). On price, ads and in-app purchases there is nothing between them.
