Was a bit worried that this was discontinued, glad it got an update. Did have an issue with a read-only library, but deleting the old one and making a new one fixed it. Edit: Trying to set the author name character limit in list view causes the app to freeze before returning to the list view, without being able to change the settings.

It gets my EPUB books from my Caliber server to my phone.
★★★★☆SuperLink2013· May 8, 2025
Great application and pretty much delivers on everything it offers!! Ther is only one issue I have found with no clear solution. It doesn't recognize, as a reader, moon reader pro. Therefore, for reading the books, I have to manually open moon reader pro.
★★★★☆Jennifer McGaffey· Dec 31, 2023
I have used and loved Caliber Companion for years; it is the best way of getting books from caliber on my computer onto my phone for reading. The latest update has made things much more difficult, though; while I can still get and mark books I cannot open a book in any reading app (I've tried my usual FB Reader, Moon+, Aldiko...). It will happily attempt to open a book in Songbook - at least, that's the app that pops up when I hit Read. The book doesn't actually open.

This was my favorite app. I used it for years, but the new update killed it. Caliber will not recognize any of my ebook reader apps, so I can no longer use it. I'm going back to paper books and canceling prime subscription.
★☆☆☆☆Dermot Lacey· Dec 8, 2025
Abandoned by developer and now won't connect to my online caliber library.
★☆☆☆☆Mark Holman· Dec 27, 2023
This app was fantastic 5 stars until the most resent update (now < 1 star) which has broken it for most users with any largish caliber library. If your not lucky enough to have backed up the app before it updated a workaround is to get the amazon app store and install their version of caliber companion (ensuring this is set to NOT update)
