User reviews

Finally

Update 2: It’s working again and I can’t rate the new dev highly enough for knowing there was a niche that needed to be filled and picking up the torch. Thank you for seeing the value in this.

Update: Calibre version 9 bricked it, if you absolutely rely on this app stay on the latest version of 8, doesn’t look like anyone’s seen a developer response for a fix in a few weeks now. Brilliant 5 star app, really hoping the dev returns to it.

There’s a few things I’ve learned in all my time spent meticulously curating, indexing, and cataloging my library through calibre and one of those is that certain file types, regardless of what you assign them in Calibres own metadata fields, do not hold certain types of metadata. So PDFs (and irritatingly enough, CBR/Zs) aren’t capable of being organised by series in e-readers. They also struggle with cloud syncing in the way that while they sync physical files, they won’t just show what you have in your cloud for download, and they certainly don’t keep that organised either.

CalibreSync completely solves these issues by not only mirroring your calibre library the way you’ve designed it, but also by making your collection viewable and searchable without needing physical copies of the files on your device (via cloud syncing), and downloadable on demand, whilst still being able to scroll through them all in an easily accessible catalogue of your own design. You can even open your books from here into your chosen e-reader. This is exactly the type of app I needed, and well worth the payment.

Excellent

Permet d’avoir sur son iPhone une ou plusieurs bibliothèques Calibre accessibles car stockées dans un service cloud. Permet de récupérer un/plusieurs livres et les ouvrir dans son lecteur favori. Bien sûr fonctionne en « lecture seule » sur le service cloud. Pas d’écriture vers le cloud.

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.

Calibre Sync funktioniert wieder, vielen Dank!
