Description by doen1el (from Google Play)

This is an unofficial companion application for Calibre Web (which also works for Calibre Web Automated) that allows you to browse your book collection and download books directly to your device. You can also interact with your books by marking them as read, unread or bookmarked. It is also possible to send books directly to your e-reader (Kindle/Kobo) thanks to the great work of send2ereader.

Recent changes:
Feat: New "Use SSO session for downloader" option lets the downloader work behind the same SSO proxy (e.g. Authelia, Authentik) as Calibre-Web, including covers and automatic re-login
Fix: The downloader now shows a clear error instead of a JSON error when an auth proxy returns its login page
Fix: Logging in and automatic re-login work again on Calibre-Web-NextGen, which now answered with "CSRF token not found" or "Session not accepted"

Comments on Calibre-Web-Companion for Android

★★★★★ Richard Priest · May 29, 2026

Works very well. I've performed uploads, downloads, reading on device, archiving and editing of metadata and all have worked flawlessly so far.

★★★★★ Todd Jahns · Jul 20, 2025

Simple and gets the job done! Found this on Reddit and it's great. It would be nice if Caliber Web supported sending stuff to my Kobo, but this does the trick also!

★★★★★ Znutar · Sep 4, 2026

Works beautiffly make sure you have all the admin rights to upload books

★★★★☆ Babatunde Olarenwaju · Jul 31, 2026

This app is useless. There is sign. I can't open it

★☆☆☆☆ just Greg · Aug 25, 2025

Unable to set up or login to caliber or even operate as a stand-alone app. Can't load any books that I have available, so it's totally useless.

★★☆☆☆ Jason Grantz · Apr 18, 2026

Sorting by title doesn’t work properly as none of my books even show up when I select that option. When I sort by author, only the first 19 books appear and the rest never load. The only sorting method that seems to work somewhat reliably is by newest title, which makes browsing my full library really frustrating.
