Response from developer

Hi, the new version of the app should fix the issue, please check it out, cheers.

Works with calibre 9

For anyone looking, the app has recently been taken over by a new developer and I can confirm it works now with calibre 9 — specifically I have my library in iCloud Drive, and everything does sync in and is accessible without issue.

I would love a bit more customizability with the viewing options, but this does do everything in terms of displaying the library and being able to filter and download books without needing my computer on and running the content server in order to access my books on another device with all the metadata attached.

New developer

Now being supported again, great news excellent app. A must have if you have Calibre.

Mostly great except the popup you can’t get rid of

Notice reappears every launch even without configured cloud accounts/keychain use.”

Response from developer

Hi, You can dismiss that notice, after that, it will not show again. Cheers

Parfait compagnon pour Calibre

Vraiment génial pour avoir un accès à sa bibliothèque Calibre depuis n’importe où ! Fonctionne parfaitement avec calibre v9 (ou v8).
