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. No automatic third-party fetching — the choice is always yours.
