title_body: E-reader that syncs progress across Linux and Android? I've found some e-readers that support Linux and Android such as FBReader, but are there any that can sync progress across the two?
upvoted_answer: There's a way, but it's kinda tricky.
  
  There's a bunch of android apps which sync the progress across the devices (like Moon+ Reader). So, if you can set up an Android emulator on your Linux machine, that should do the trick.
