Shelfieline

Your private study, in your pocket. Shelfieline is an iPhone / iPad app that turns reading from a list-management chore into a personal experience. We've recreated a real bookshelf in digital form — spine textures, varying book heights, the heft of the shelf itself, all carefully redrawn. The dark, "private den" aesthetic is built for readers who care about how their library looks. ▼ Key Features 【Study Carousel】Multiple bookshelves arranged side-by-side. Swipe left and right to switch. Adjacent shelves peek in from both sides so you see your whole collection at a glance. 【Bookshelf Detail】Your books displayed as realistic spines. Pinch to zoom — rows recalculate automatically based on book count. Letterpress-style title and author detail, with paper / cloth / leather material rendering for each book. 【Three Ways to Add Books】 ・Scan ISBN barcode (auto-fills bibliographic info) ・Manually enter title / author ・Share a cover image from Safari → assign to a book in-app Cover images are captured by your camera or chosen from your photo library.
