LibMate
Private library companion: catalogue physical and e-books, track exact book locations, coordinate peer loans, and accelerate reading.
Book lovers face a persistent dilemma: physical libraries scattered across rooms, shelves, and storage boxes; digital e-books fragmented across disconnected apps; books lent to friends that disappear without a trace; and an ever-growing reading backlog that feels impossible to conquer.
LibMate unifies physical and digital reading into a single local-first platform designed for serious readers. With fast ISBN barcode scanning and batch e-book ingestion (EPUB, PDF), you can build an organised, beautiful inventory of your entire collection in minutes. Assign physical books to specific bookcases, shelves, rooms, or storage bins so you always know where every volume lives.
LibMate also keeps your books circulating with a built-in peer lending ledger. Keep track of which titles you have lent to friends or colleagues, set gentle return reminders, and browse shared collections to borrow books from fellow readers. When you are ready to tackle your reading stack, switch to the integrated RSVP (Rapid Serial Visual Presentation) speed reader, which flashes words at your optimal cadence with bionic focal guidance to help you absorb knowledge up to 3x faster without eye strain.

Frequently Asked Questions
How does physical book location tracking work? +
When you catalogue a physical book, you can assign it to a custom location hierarchy—such as 'Living Room > Main Bookshelf > Tier 2' or 'Storage Box #4'. You can filter your library by location at any time to see every book in a specific spot.
Can I import my existing library from Goodreads or a CSV file? +
Yes. LibMate includes a universal importer in Settings > Import & Export that accepts CSV exports from Goodreads, LibraryThing, and Calibre, automatically matching titles and book covers.
What e-book formats are supported by the integrated speed reader? +
LibMate supports DRM-free EPUB, PDF, TXT, and Markdown files. The speed reader parses the text stream and displays it via Rapid Serial Visual Presentation (RSVP) with customizable pacing and bionic focal points.
How does peer book loaning work? +
When you lend a book to a colleague or friend, mark it as 'Loaned' in the book details, select or enter the borrower's name, and optionally set a return target date. LibMate tracks the status and reminds you when a book is due.
Is my reading data stored on external cloud servers? +
No. LibMate uses a sovereign local-first SQLite database stored directly on your device. Your reading habits, book notes, and personal collection remain strictly private.
