EverReed field guide
Calibre Companion was, for years, one of the go-to mobile apps for people who kept their ebook library in Calibre. Since then, the mobile landscape has shifted, expectations for reading apps have grown, and a lot of readers have started looking for something that pairs the same "connect to a Calibre library" workflow with a more modern reader, better tracking, and a proper recommendations layer. EverReed is one of those options. It connects to a Calibre content server through OPDS, keeps your files on your own hardware, and adds the parts most people now expect from a reading app: a clean mobile reader, series tracking, a TBR, reading stats, and taste-driven recommendations. This page lays out what changed, when Calibre Companion may still be enough, and where EverReed offers additional value.
What you get
Calibre Companion was a mobile app focused on connecting to a Calibre content server and reading the books it published. It was popular precisely because it treated "your own Calibre library" as a first-class source in an era when most reading apps only cared about their own store.
A lot of readers are now looking for one app that handles more than just reading: they want a modern mobile interface, series tracking that keeps up with long-running series, personalized recommendations that draw on their actual library, and reading stats that make the year feel measurable. That is a bigger surface than the original Calibre Companion set out to cover.
EverReed ships a built-in EPUB and PDF reader with adjustable typography, light and dark themes, section-based pagination, in-book search, table of contents, and a dictionary. Books served through your Calibre content server open in the same reader used for uploaded files.
The app is built for touch-first reading. Library views, series pages, and the reader itself are designed around the way people actually use phones and tablets in 2026, not carried over from a desktop-first era.
Progress, bookmarks, highlights, and notes are stored in your EverReed account and follow you across devices. Reading history, streaks, and a yearly goal live alongside your library so you can see the shape of your reading, not just the current position in one book.
EverReed builds a Taste DNA profile from the books you rate, review, and finish, and uses it to describe what actually pulls you in — pacing, mood, tropes, narrative structure. That profile powers recommendations and gives you a genuine read on your own taste.
Long-running series get a first-class treatment: what you have read, what is next, and what is coming up. EverReed distinguishes mainline entries from novellas and extras so a "next book" recommendation is actually the next book.
Recommendations pull from your Taste DNA, your library, and the books you have finished — including the ones served by your Calibre content server. They are not tied to a store; they are tied to your actual reading.
Both formats open in the same reader whether the file is uploaded to EverReed or streamed from your Calibre server. Progress and highlights stay attached to the book, not to the device.
If your only requirement is "connect to a Calibre server and open books," any app that supports Calibre's OPDS feed will do the job. EverReed is aimed at readers who also want tracking, series intelligence, recommendations, and a modern reader in the same place.
Useful details
It covers the same "connect to a Calibre library and read on mobile" workflow through OPDS, and adds tracking, series intelligence, and recommendations on top. Whether it is the right replacement for you depends on which of those features you care about.
Yes. Calibre stays on the desktop as the source of truth for your library. EverReed connects to Calibre's content server over OPDS; it does not replace Calibre itself.
Through Calibre's content server, which publishes an OPDS catalog. EverReed reads that catalog over HTTPS and streams books from it into the built-in reader.
As long as your Calibre content server can publish it as an OPDS feed reachable over HTTPS, EverReed can connect to it.
Yes — inside EverReed. Progress, bookmarks, notes, and highlights live in your EverReed account. They are not written back to Calibre.
No. Files stay on the server you already run. EverReed does not sell, host, or distribute ebook files.
EverReed is not open source. Calibre and Calibre Companion are independent projects with their own licenses. If open-source software is a hard requirement for you, that is worth noting up front.
EverReed has a free tier with core reading and tracking, and an EverReed Plus tier that unlocks advanced insights and recommendations. Connecting a personal library server is not gated by the free plan.
Yes. You can upload EPUB and PDF files you already own, track series, use recommendations, and manage a TBR without ever connecting a server.
The same way. Any OPDS-compatible catalog served over HTTPS — Kavita, Komga, or another server — can be added as a personal library source.
