After digging a little further, there is an iOS alternative called Readest (https://github.com/readest/readest) available in the App Store. Along with this video to walk you through the sync process https://m.youtube.com/watch?v=WfP-qLMhMso. Overall, it took about an hour for me to get everything set up after I found these resources and I’m super stoked.

Is KOReader android only? I don’t see it in the App Store. The main feature of the Amazon reader apps for me is the position sync so I can read on the go. I’d hate to lose that feature.
