Dashboard sections offer per-section card styles, and ordered read lists can continue like series with reading state synced across devices. One Lists page unifies collections and read lists on every platform, with pinned items first. On supported servers, smart lists evaluate saved searches live and can be created and edited in the app, and reading stats come from the server with current and longest streaks, falling back to on-device data otherwise. Select multiple books and series to mark them read or unread, or add them to a list in one go. iPhone offers dedicated Library, Lists, and Search tabs for content-first browsing. KMReader keeps a local database for responsive browsing, dashboards, logs, and downloaded-library workflows, including large libraries. Dashboard library scopes stay tied to each saved server, and widgets mirror refreshed dashboard content. - Offline and sync Download books for offline reading, set per-series and per-read-list download policies, browse downloaded items with count and storage summaries, queue dashboard sections, keep reading with iOS background downloads and Live Activities, prepare local pages on demand with offline-first reading, and sync progress when you reconnect. Sync missing covers for downloaded books, series, read lists, and collections so offline browsing stays visual. - Multi-server and admin tools Save multiple Komga servers, protect private servers with device authentication, and switch instantly. Sign in with password or API key — the login screen can create a key for you — set up a brand-new Komga server right from the login screen, and manage API keys in the app. Edit metadata, manage libraries and media, find missing posters or duplicates, and browse, export, or clear paginated logs. A Server Info overview reports version, uptime, CPU, memory, disk, and content totals, with live task queue, sessions, and scheduled-task pages, on stock Komga servers too. On servers with the komf integration, Identify, Match, and Reset Metadata fetch metadata without leaving the app. KMReader targets Komga 1.20.0+ and supports API v1/v2. KMReader UI is localized in English, German, French, Japanese, Korean, Simplified Chinese, Traditional Chinese, Italian, Russian, and Spanish.

MyBibliotheca is a private, ad-free reading tracker, book organizer, and reading journal for your whole reading life. Track books, log reading sessions, organize your to-be-read list, and discover the stories behind your reading habits. Looking for a Goodreads or StoryGraph alternative? Import your existing library and keep your books, ratings, notes, and reading dates together without social pressure or a crowded feed. TRACK EVERY FORMAT Keep hardcovers, paperbacks, ebooks, and audiobooks in one personal library. Log pages read, audiobook minutes, and reading sessions. Record where you left off, save start and finish dates, and revisit your reading history. Track audiobook listening time and completion percentage alongside your print and ebook progress. BUILD A LIBRARY THAT MAKES SENSE Search for books by title, author, or ISBN, or add a book manually. Organize your collection with custom bookshelves, series details, ratings, and private notes. Move books between Reading, Up next, Plan to read, Finished, and DNF without losing their history. Keep reference books and other titles on a dedicated Private shelf that stays out of public profiles and recommendations. TURN YOUR TBR INTO YOUR NEXT GREAT READ Do more than collect an endless list of books. Create private TBR lists, set priorities, arrange your reading queue, and tag books by mood. Save why you added a title so a friend's recommendation or an intriguing review doesn't get forgotten. Filter by author, genre, format, mood, or length to find a book that fits the moment. BRING YOUR READING HISTORY WITH YOU Import Goodreads, StoryGraph, or other supported CSV exports. Review column mappings before importing your books, statuses, ratings, notes, and reading dates. Start with the library you've already built instead of entering everything again. CONNECT KOREADER AND READWISE Sync ebook reading positions across configured KOReader devices and link progress to your MyBibliotheca library. Use the separate KOReader plugin to bring highlights and notes into your book records. Connect Readwise to import saved highlights and notes, then match them to books in your collection. Keep memorable passages and your own reflections close to the books they came from. KEEP MORE THAN A STAR RATING Save book notes, highlights, and reading-session reflections. Record an overall rating or look more closely at plot, characters, and prose. Export highlights and notes in Markdown or plain text so your reading journal remains useful beyond the app. UNDERSTAND YOUR READING HABITS Explore reading streaks, activity calendars, pages read, listening minutes, and monthly progress. Year in Reading brings together finished books, favorite reads, formats, returning authors, and your month-by-month pace. See how your reading changes over time, not just how many books you've finished. REDISCOVER YOUR OWN SHELVES Shelf Archaeology helps you revisit unfinished and forgotten books already in your library. Find another possibility in your existing collection before adding something new to your TBR. SHARE THE MOMENTS YOU CHOOSE Create downloadable reading calendars, book recap cards, and monthly or yearly reading summaries. Share a finished book or a snapshot of your statistics without publishing your entire reading history. An optional public library page lets you choose whether to include ratings and your reading streak. STAY IN CONTROL Your library is private by default. There are no ads or attention-demanding social feeds. Export your library and reading logs as CSV, use the read-only API to connect supported tools, and access your account on your phone, tablet, or computer. Whether you read a chapter before bed, listen on your commute, or move between several books at once, MyBibliotheca gives your reading life a place to belong. Made independently in Minnesota.
