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. The dark, "private den" aesthetic is built for readers who care about how their library looks. ▼ Key Features 【Study】Your bookshelves side by side. Swipe to switch; neighboring shelves peek in from both sides. On iPad the shelves fill the screen. 【Bookshelf】Your books as realistic spines. Pinch to zoom and the rows rearrange themselves. Paper, cloth and leather textures with letterpress-style titles. Long-press a book to lift it and drag it into place. 【Adding Books】 ・Scan an ISBN barcode (fills in the title, author and page count) ・Continuous scan: scan book after book, then shelve them all at once. Books you already own are flagged ・Enter the title and author by hand ・Share a cover image from Safari and assign it to a book Cover images come only from your camera or your photo library — the choice is always yours. 【Search】 ・Search every shelf by title, author, or the text of your notes ・Filter by status: want to read / reading / finished / stockpile 【Reading Status】 ・Four states, page progress for books in progress, 5-star ratings for finished books ・Start and finish dates 【Reading Stats】 ・Books and pages finished per year, with a month-by-month chart ・A yearly goal, and a breakdown by status 【Reading Diary】 ・Multiple notes per book, grouped by month ・Optional photo attachment 【Shelf Memo & Reading History】 ・A memo and photos for each shelf ・A bank-passbook-style timeline of books added, started, finished and noted 【Share Shelfie!】 ・Turn a shelf into an image of your study and post it ・Preview before sharing; choose 9:16, 4:5 or 1:1 ・Or make an image of the books you read this year 【Flat View & Organize Mode】 ・Switch between spines and a grid of covers ・Select several books and move them to another shelf at once 【Export & Backup】 ・Export your book list as CSV ・Create a backup that includes covers, notes and shelf memo photos, and restore from it 【Shelf Materials & Wallpapers (Pro)】 ・6 shelf materials: Walnut, Ebony (free) + Oak, Maple, Teak, Mahogany (Pro) ・5 wallpapers: Plain (free) + Linen, Wood Panel, Dark Concrete, Leather (Pro) 【Widgets (Pro)】 ・Library size and books finished ・A shelf widget showing your actual spines ・The book you're reading and how far you are (also on the Lock Screen) ▼ Privacy ・Your books, notes and photos stay on your device. No account, no email collected ・No user tracking, no ads ・To improve the app, only anonymous usage counts that cannot identify you are sent ・Cover images come only from your camera or photo library ・Book information is looked up through the official openBD, National Diet Library Search and Open Library APIs ▼ Plans ・Free: up to 3 bookshelves and 30 books.

Verdict
The clearest difference is price: Shelfieline at Free against Booket's $3.99. Shelfieline also leads on update cadence (every 2 days vs monthly). Booket's advantage is in-app purchases (none vs 1). On ads, device support and iOS requirement there is nothing between them.
