A warm, unhurried home for your reading life. Shelfd keeps a quiet record of everything you've read and everything still waiting — without turning your hobby into a job. No leaderboards. No guilt for the week you didn't finish anything. HOWEVER YOU READ IT Paper, ebook, or audiobook — track them side by side on the same shelf. Audiobooks count down in hours and minutes remaining, the way your listening app shows them, so there's no maths to do when you log your progress. YOUR SHELF, ACTUALLY SHELVED Finished books stand as real spines, coloured from their own covers. Browse them as a shelf or a list, and build your own collections for classics, comfort rereads, or whatever you're hoarding this month. SPIN THE WHEEL Too many books, not enough decisions. Load up your TBR, give it a spin, and let fate choose your next read. A GOAL WORTH HITTING Set a books-per-year target and watch the arrow move toward the bullseye. Miss it and nothing bad happens. Hit it and something rather nice does. THE SHAPE OF YOUR TASTE See which genres you actually gravitate to, how you read — paper, screen, or headphones — and the quiet trends across your year. ACHIEVEMENTS, STAMPED Every finished book earns a mark from the Archivist, who keeps your records in impeccable order and is quietly more invested than he lets on. BRING YOUR LIBRARY Coming from Goodreads or StoryGraph? Import your whole history from a single file and pick up where you left off. Back up your shelf whenever you like — your library is yours, and it stays on your device. SCAN AND GO Point the camera at a barcode and the book is on your shelf, page count and cover included.
