KOReader Sync

CWA has built-in KOReader progress sync; no separate kosync server is needed.

  1. In KOReader, install the CWA plugin: visit http://your-cwa:8083/kosync for download and install instructions.
  2. Point the plugin at http://your-cwa:8083 and log in with your CWA username and password.
  3. Read on any device. Progress syncs back to CWA, and from there to Kobo if Kobo sync is enabled.

Matching filenames across devices (OPDS downloads). If you download books to KOReader over OPDS and sync progress by filename across several e-readers, turn on Use server filenames in KOReader's OPDS catalog settings (the checkbox when you add or edit the catalog). By default KOReader names a downloaded file Author - Title.epub from the catalog entry, which differs from the on-disk library name Title - Author.epub and forces a manual rename. CWA already sends the library name in the download's Content-Disposition header; with Use server filenames on, KOReader uses that name, so the file matches your library and your other devices without renaming.


See also Kobo Sync for reading on a Kobo e-reader.
