I have an established calibre content server that is easily accessible via LAN or WAN using any browser.but this app clearly is incapable of finding my server on port 8083. if the dev is limiting to 8080, thats just idiotic, why even bother provide a setting to input an custom address? don’t waste your time on this app. its completely useless

It doesn’t hand hold you through the process, but ultimately it’s rather simple. There’s a setting in the “Sharing over the net” section of the preferences in the desktop version that starts a content server. You need the IP and port of that to connect to it from your phone app. If you’re having a problem, it may be that you haven’t started the content server. There’s documentation for calibre online that talks about how this general process works for apps like these.

I agree with the other comments I have seen wishing there were instructions. However, I was able to figure it out with a little trial and error. It works perfectly once you get things set up. He app updated with my Calibre library and allows an easy search.

Was hopeful this app would let me read books from my Calibre app on my windows laptop, but it crashes when trying to sync. Basically a useless app.
