CollectBook is the personal catalog app that lets you collect and organize anything you love. Create collections for the things that matter to you — movies you've watched, books you've read, restaurants you've visited, figures you've collected, games you've cleared. Set your own theme, add items with photos and notes, and build a personal database that's entirely yours. --- Collections for Everything --- There's no limit to what you can track. From hobbies and wishlist management to reviews and rankings — CollectBook adapts to any collection. Each collection gets its own rating style, so every theme feels right at home. --- Four Rating Styles --- Choose the rating method that fits your collection: • Star Rating (1–5): Perfect for movies, books, or anything you want to score • Rank (S / A / B / C / D): Great for games, spots, or tier-list style rankings • Check (Done / Not Done): Ideal for reading lists, bucket lists, and to-do tracking • Custom: Define your own scale with your own level names — up to 20 levels --- Powerful Filtering with Attributes --- Add custom attributes to each collection — like "Noodle Firmness" for a ramen log, or "Genre" for a music library. Filter items by any combination of attributes to find exactly what you're looking for. --- Search, Sort, and Browse --- Full-text search by name. Sort by rating, rank, check status, or date added. Group items by evaluation so you can see all your S-rank picks or 5-star favorites at a glance. Switch between grid and list view to browse your way. --- Bulk Add and Edit --- Select multiple photos at once and add them all in one go. Set names, ratings, and attributes in bulk before saving. You can also select multiple items to edit or delete them together — perfect for large collections. --- Your Data Stays on Your Device --- Everything is stored locally on your device. No accounts, no cloud sync, no data sent to external servers. CollectBook works fully offline — your collection is always private and always available. --- Backup and Restore --- Keep your collection safe with flexible backup options. Save backups inside the app (multiple generations) or export as a JSON file to Files or AirDrop. When restoring, pick individual collections to bring back — no need to overwrite everything. Auto-backup runs quietly in the background each time you leave the app. --- Key Features --- • Create and manage multiple collections • Add photos, notes, and custom attributes to items • Four rating styles: Star, Rank, Check, and Custom • Bulk photo import and bulk delete • Grid and list view • Search and filter by name and attributes • Group view by rating, rank, check status, or custom level • Backup and restore (in-app + file export) • Japanese and English support Start building your personal collection today.
