ShelfBuddy is your digital bookshelf: beautiful, calm and built entirely around reading. Keep track of every book and audiobook you own, are reading, have lent out or still want. Your whole library, neatly organized, and your data always stays in your hands. YOUR LIBRARY, ORGANIZED Create as many shelves as you like, for example Fantasy, Thrillers or Classics, keep wishlists, and plan what to read next with a reading list. A book may sit on several shelves, and copies marked "collected only" count neither as read nor as unread. Manage genres and tags across all your books at once, and "Edit fields" sets author, genres and tags for several books in one step. Filter your TBR pile by shelf, format, genre, tag or language. BOOKS AND AUDIOBOOKS The overview keeps books and audiobooks apart: audiobooks get their own series, wishlists, loans and statistics. Count them as read if you like, and keep manga and comics separate. BOOK SERIES AT A GLANCE See for every series which volumes you own and which are still missing, and add them to your wishlist or a shelf with one tap. Discover suggests book series and audiobook series picked by your taste, search puts the series you look for first, and you get notified when a new volume is released. RATINGS AND RECOMMENDATIONS Rate your books in quarter stars and see ratings from Thalia and other ShelfBuddy readers alongside. "Popular on ShelfBuddy" shows what the community is reading a lot right now, next to recommendations picked by your taste and "Next in your series". TRACK YOUR READING Reading tracker and reading journal in one: status, start and finish dates, reading progress, notes and quotes, also for books you have read more than once. "Read as" remembers when you read a book as an eBook or a borrowed copy while the print edition stays on your shelf. READING SESSIONS WITH A READING TIMER Start a reading session and the timer runs along. When you're done, enter your page and ShelfBuddy updates your progress and reading pace. Log past reading time after the fact, and start your next session from the home screen, the app icon or a widget, with a Live Activity on the Lock Screen. INSIGHTS: GET TO KNOW YOUR READING HABITS A reading calendar shows which days you read and how much. See the time of day and the weekdays you read most, which genres get most of your reading time, your records, your spending per week, month and year, and a short written summary of your reading year. Insights are part of ShelfBuddy Premium. YOUR READING RECAP Share your reading year or month as an image: six templates, headline styles, reading time or pages, your covers and highlights. ADD BOOKS IN SECONDS Scan the ISBN barcode, search millions of books or add books by hand. Import your library from Goodreads, StoryGraph, Reado and other apps, genres and covers included. "Missing details" fills in page counts and publishers, and you can export your whole library as a .csv spreadsheet. AUTHORS AND LENDING Follow your favorite authors in several languages and get notified about new titles. Lending remembers who has which book, with a reminder to get it back, and borrowed books remember when you got them. YOUR DATA, YOUR CHOICE Keep everything 100% local on your device, or sync via iCloud or Google Drive. Export a complete backup at any time. With ShelfBuddy Premium you can also open your library in the browser on your computer at app.shelfbuddy.de, linked with a QR code, no account needed and encrypted on your device. ON IPHONE, IPAD AND IPHONE DUO On iPad you work with a sidebar and the book page side by side. Optimized for iPhone Duo: unfolded, ShelfBuddy uses the large screen like a tablet. ALL YOURS Dark mode, selectable accent colors and available in four languages.

You know roughly how much you read. Readerly tells you exactly. Readerly turns your reading history into a clear picture of your reading life: how your pace changes through the year, what you reach for, which authors you return to, when you read most, and how this year compares with every year before it. Save Private Notes & Quotes, too, so the parts of a book you want to remember stay with your reading life. No account. No sign-in. Your library stays on your iPhone. WHY THE NUMBERS HOLD UP A chart is only useful if the number under it is right. Audiobooks are counted in hours. Insight cards show the evidence behind what they say: how many sessions contributed, what window was measured, and whether there is enough data to support the result. If there is not, Readerly says so instead of inventing an average. Your reading data also outranks the catalog. If you are on page 628 of a book a database says has 623 pages, Readerly accepts 628 and offers to correct the book length. Reopen any reading session and change the date, pages or minutes. Start and finish dates are yours to set. Correcting your own reading history is never behind Readerly Pro. WITHOUT A SUBSCRIPTION • Three free Library choices: Plain, The Book Dragon and A Distant Kingdom • Unlimited books and reading sessions, stored on your device • Private Notes & Quotes • Haptic quarter-star ratings, so a book can be 4¼ instead of being forced to 4 or 4½ • Searchable genres and custom cover images • Log the page you are actually on, not pages-read arithmetic • Live reading pace and projected finish date for every active book • Barcode scanning • Bookstore Mode: continuously scan shelves and instantly see whether a book is already yours or already read • Import from CSV, TSV, XLSX or ZIP • Preview every addition, update and conflict before anything is saved • Readerly reconstructs your reading history from dates in your file, marks estimated dates, and lets you undo the entire import with one tap • Optional AI Import Assistant for messy or unfamiliar exports • Cover and description lookup for books missing metadata • Books Finished, Day Streak, Pages Read and Minutes Read • Two charts on your real numbers: Books Finished by Month and print, digital and audio mix • Explore your reading by year • Share cards as square images or silent 9:16 videos READERLY PRO Readerly Pro turns your log into a deeper view of how you actually read. It also includes thirteen additional Library wallpapers. Unlock deeper charts and insights, including reading momentum, daily rhythm, the hours and weekdays you read, genre currents, per-book reading journeys, genre mix, rating shape, author affinity, completion patterns, length versus rating, a six-axis taste profile, and a deck of the strongest insights your history can support. Choose any month and tap pages or listening bars to see the books behind your totals. Tap a rating, author or genre to see the books behind the number. Share your reading highlights. PRIVATE BY DESIGN Your books, sessions, ratings, notes, quotes, dates and progress live in a private database on your iPhone. Book lookup sends only what identifies the book, such as an ISBN or title and author. No ads. No third-party analytics. No tracking. AI IS OPTIONAL Readerly includes two optional AI tools on the import screen, and neither runs unless you ask. It can send titles and authors of uncategorized books to Anthropic's Claude to suggest a genre from Readerly's fixed list, or send your file's column names and limited samples to suggest how they map. Readerly asks first and tells you what will be sent. Readerly Pro is an auto-renewing monthly or yearly subscription at the price shown before purchase. Cancel any time in your Apple Account settings. Privacy Policy: https://thereaderlyapp.com/privacy/ Terms of Use: https://thereaderlyapp.com/terms/

Verdict

The call

The clearest difference is ads: Readerly at none against ShelfBuddy's shown. ShelfBuddy's advantage is update cadence (every 2 days vs weekly) and ratings volume (5 vs 1). On price, rating, in-app purchases and monetization model there is nothing between them.
