Calibre Sync reviews
3.9 out of 5, based on 159 reviews.
What people like
- Fast syncing and browsing
- Easy download to other apps
- Clean interface with no junk
What they complain about
- Broken since Calibre version 9
- Developers ignore support messages
- Syncing fails for new books
Great app. Works well.
It worked great to connect to my Calibre library. Syncs easily and gives me a great way to browse through my collection.
Lies
The new update from the new dev is a lie. The new calibre database 9+ doesn’t work. If/when it does I’ll change my review.
Mostly great except the popup you can’t get rid of
Notice reappears every launch even without configured cloud accounts/keychain use.”
Used to be great
This was my go to app for managing ePubs. I recently had to switch to Box for online storage and, while the app works great between two pcs, the iPad app no longer works (at all). Unfortunately, I want to read epubs on my iPad. Thus, the value of Calibre is dramatically reduced. The fact that there is no support just makes the problem worse.
Syncs Most books
The app worked great at first but stopped syncing new books added to Calibre. I hoped that changing cloud services would help but it did not. I wish iCloud worked with this app to try that. It’s been 5 months since the dev said iCloud would be integrated in the near future. With what books I can sync the app is great.
Works again!
Very fast and efficient way to get books from your Calibre installation.
No longer works. Don't buy.
As of the release of Calibre 9 this app is broken and the developer has not responded on when it will work again. Don't spend your money on it. If it is fixed and works with Calibre 9 I will delete /update this review. I really liked this app.
Love it, but Needs update
I love this app, but since Calibre version 9, this app no longer able to sync/connect to the database. Please update the app :).
A fan
This app is fantastic. It does what it's supposed to do, but it could use more features like displaying bookshelves, etc. I have both CC and this app; I'm attempting to use this as my primary, but it lacks features. It's a good beginning.
New dev fixed the app!
Thanks to the new dev, this app works great again
Disappointed
Purchased the app and could not sync Calibre to iPad after numerous attempts. Tried to get a refund but Apple refused. “Not eligible for refund” Buyer beware
Seems useful, but no iCloud
This is exactly the app I was looking for with one exception: there is no iCloud integration. I hope the developers can eventually add that functionality.
Not there yet
Wanted to like this app as a replacement for Calibre Companion. Not quite there yet. Had issues connecting to Calibre as a smart device, ultimately went for the connect to server option. Reached out to the developer and never replied back. Some things are not as intuitive as they should be. FAQ needs updating. Even better yet would be a nice YouTube video. Oh well. Let’s see how frequently this app is updated.
Works now with Calibre 9!
The new update is working for me as of this writing! Syncing worked without any hiccups. I just can’t seem to keep the Important Notice from showing up every launch. Love this app!
Stopped working
It worked the first time I did a sync but then failed on each subsequent atttempt. I would have given it a 5 before then but now it is useless and the developers haven’t responded to any support mesaages.
Failed to download metadata
It seems to be good app, but when I'm trying to connect with my webdav server Nutstore, I failed. The app said failed to download metadata.
Super Helpful, Easy Library Access
Recently started to build out my ebook library in Calibre and was looking for an easy way to get the books from my cloud storage (pCloud) into my preferred ebook reader apps as most of them do not natively support pCloud. This was exactly what I needed! I don’t have a giant library of books, about 1,400, but the app syncs and downloads the covers so it’s really responsive. This makes browsing and searching the library on my phone super fast and easy! When I want to load up a book I simply download it in the app and then share it to the ereader app. Super simple! If I had to provide one critique it would be that the UI could maybe use a slight refresh to give it a more modern feel. But functionality is most important and in that regard it 100% gets the job done!
Doesnt work at all
I paid for a version on my tablet and phone it doesnt work wry disapointed i tried the google drive sync says cant find calibre file its not a calibre file its where i store my backup books idk how to export a calibre specific file calibre doesnt offer this so idk what a calibre file they are speaking of second cant connect to the server at all i can connect on a different free app so i know it works its just this app doesnt allow me to read the book just download it, thats not what i want i want to read it within this app. This app doesnt work whatsoever. Must be all the other reviews are fake. I want my money back this is such a scam.
Just opened up a whole new world…a crack
I have thousands of ebooks and have been limited to accessing them via Calibre on my pc, which I then use to transfer to my Kindle. Yes I can access the books via OneDrive on my iPad but it’s not the smoothest or best managed. So I was delighted to find this app. Actually, I’m delighted to find this app works as advertised and quite quickly. It’s much easier to find and download my books and digital comics. My one critique is that it wants to use the Mail app, rather than what the user has set their default mail app to be. I prefer Outlook so I never bothered to setup the Mail app. When I tried to use the “send to Kindle” function it failed because of this limitation. And because I’ve configured my accounts in Outlook and the mail setting, I can’t add them to Mail. While I appreciate being able to download and read on any of my iOS devices, I prefer doing so in Kindle as it syncs progress across all devices. For me, five stars would be: Fix the app to use the configured mail app Have an option for “automatically send to Kindle” Set preferred reading apps by type ie set Comix as the preferred app for cbr Being able to launch preferred app from this app
Very Nice app, and Lovely Hidden Tetris Game
Very Nice app to connect your cloud based Calibre Library and have it mobile. Also Loved the Hidden Tetris Game when clicking the logo of the Calibre App inside the app.
Horrible
The app won’t find any of my files on local storage where it shows to place the files.
Ok cool, that’s all I needed
Searchable read-only access to a cloud-located calibre library, which can download a book and punt it over to a compatible reader app. Clean interface, no weird nonsense!
Best Calibre Mobile App
Best app for using your Calibre library On-The-Go.
It works flawlessly
Best app ever to connect to your Calibre libraries on the cloud. Very well thought and full of useful features like handling of multiple libraries and local storage of books in a folder accessible with the Files app.
One of the better Calibre related apps
It’s more like a 4~4.5-star app, however, comparing to other calibre-related apps makes this one feel like a 5~6-star app. By the way, what is virtual view? Couldn’t find introduction in official site.
