A Calibre Companion alternative for reading your library on phone

As of September 2026, Calibre Companion is active again: version 3.0 is available on iPhone and iPad, and the Android app has resumed updates. That changes the comparison. The useful question is no longer whether Calibre Companion is still maintained, but which workflow fits you better. Calibre Companion remains a Calibre-focused library organiser and connection tool, with wireless-device, content-server and cloud-library workflows. EverReed takes a different approach: connect to a Calibre content server through OPDS, read supported files inside EverReed, and keep reading progress, series tracking, your TBR, reading stats and personalized recommendations in the same place. This page explains where the two overlap and where they do not.

What you get

Designed around the way readers actually move.

  • Calibre Companion is active again

    Calibre Companion returned to active development in September 2026. Its 3.0 release refreshed the iPhone and iPad experience, and Android updates have resumed. Readers choosing an alternative should compare current products rather than relying on older descriptions of its maintenance status.

  • What Calibre Companion focuses on

    Calibre Companion is built around a Calibre-centric workflow: organizing a device library, connecting to Calibre over Wi-Fi, browsing the Calibre content server or supported cloud libraries, and opening books with a reader app. Those workflows remain useful if deep Calibre integration is the main requirement.

  • What EverReed focuses on

    EverReed is a reading companion rather than a Calibre device emulator. It connects to the Calibre content server over OPDS, opens supported files in its own reader, and keeps reading progress, series, TBR, reading stats, Taste DNA and recommendations together.

  • Read a Calibre library on your phone

    The EverReed path is Calibre content server → OPDS → EverReed. Keep Calibre as the desktop source of truth, expose the catalog over HTTPS, then browse and read it from EverReed on iPhone, iPad or Android.

  • Built-in reader and broader format support

    EverReed supports EPUB/KEPUB, PDF, TXT, safely sanitized HTML/XHTML, DRM-free MOBI/AZW3, and CBZ/CBR comics or manga through direct upload and compatible Personal Server sources. Reader tools vary by format; image-only CBZ/CBR pages use page-based reading rather than text search or highlighting.

  • Reading progress that stays with your EverReed account

    EverReed keeps reading progress and supported reading state in your EverReed account so you can resume across sessions and devices. That reading state is not written back into the Calibre database.

  • Series tracking

    EverReed tracks long-running series, what you have read, what comes next, and announced future entries. Series tracking is part of the same library experience as reading rather than a separate Calibre metadata workflow.

  • Personalized recommendations

    Taste DNA learns from the books you finish, rate, favorite, review, reread or abandon and uses those signals to explain why a recommendation may fit. The recommendations are not tied to an ebook store.

  • Not a one-for-one Calibre Companion replacement

    EverReed does not emulate a wireless Calibre device, does not replace Calibre metadata management or conversion, and does not mirror every Calibre Companion cloud workflow. If those are central to how you use Calibre Companion, keep that difference in mind.

  • Choose based on the workflow you want

    Calibre Companion may make more sense if your priority is device-library organization and direct Calibre-oriented connection workflows. EverReed is aimed at readers who want their Calibre library to feed into a built-in reader, reading progress, series tracking and personalized recommendations.

Useful details

Frequently asked questions.

Is Calibre Companion still active?

Yes. As of September 2026, Calibre Companion is active again. Version 3.0 is available on iPhone and iPad, and the Android app has resumed updates. Older descriptions that present it as inactive are out of date.

Is EverReed a direct Calibre Companion replacement?

Not one-for-one. EverReed can replace the "browse my Calibre library and read on my phone" workflow for readers who connect through OPDS, but it does not reproduce Calibre Companion's wireless-device emulation, Calibre-specific device management, or every cloud-library workflow.

How can I read my Calibre library on my phone with EverReed?

Run Calibre's content server, make its OPDS catalog reachable over HTTPS, add that catalog as a Personal Server in EverReed, then browse and open supported books from your phone or tablet.

Can I use EverReed as a Calibre reader on Android?

Yes. EverReed is available on Android and can connect to a Calibre content server over OPDS. Supported server files open in EverReed's reader and reading progress stays with your EverReed account.

Can I use EverReed as a Calibre reader on iPhone?

Yes. EverReed is available on iPhone and iPad. Connect the Calibre content server over OPDS to browse your library and read supported files inside EverReed.

Which Calibre book formats can EverReed read?

EverReed supports EPUB/KEPUB, PDF, TXT, safely sanitized HTML/XHTML, DRM-free MOBI/AZW3, and CBZ/CBR when the Calibre/OPDS source publishes a usable file within EverReed's normal safety and size limits.

Do I still need Calibre?

Yes if Calibre is where you manage the master library. Calibre remains the desktop source of truth for metadata, conversions and library management; EverReed sits at the reading end of the setup.

Are EverReed highlights and progress written back to Calibre?

No. EverReed reading progress, notes, highlights and bookmarks are stored in your EverReed account. EverReed does not modify the Calibre database or write reading state back to the source file.

Does EverReed sell or host books?

No. EverReed does not sell or distribute ebook files. A Personal Server book remains hosted by the server you control; direct uploads are files you provide yourself.

Can I use EverReed without Calibre?

Yes. You can directly upload supported ebook and comic formats you own, track series, manage a TBR, and use EverReed's reading and recommendation features without connecting Calibre.
