Otium Library

Otium is a cozy book tracker for readers who want one place for books they have read, own and wish for. Books appear on shelves as spines or covers, and tracking is meant to feel relaxed, with no timers. It can import from CSV or Goodreads and export everything at any time, so the library is never locked in.

Tracking goes deep: each format and edition, such as hardcover, ebook or audiobook, is logged separately with its own price and purchase date. Series support subseries, shared universes and reading order, and character maps show who is connected to whom and carry the cast into the next book. Stacked filters, manual or smart collections, notes, quotes and vocabulary lists, and a to-do list for ARC reviews, library returns and release dates round it out.

Social features include buddy reads with progress tracking and blurred spoilers and a shareable wishlist friends can reserve from. Reading streaks come with two freeze days, there are five themes and ten languages, and the web app can be added to a home screen like an app. A 7-day free trial is offered.
