I've been synching progress and stats between a pair of devices! It's been great since it runs well on my haul broken kindle & my android.
There is some(maybe a bit more than some) setup time to get used to the layers of menus, but it's a pretty robust app.
Oh awesome! Glad you were able to find a tool that works for you.
Unfortunately I believe it isn't available on iOS. On Android you can install it from a few sources. Directly from GitHub, or via F-Droid(or something similar). I'm with you though, that feature is key to me not scrolling forever.
I'm honestly surprised how many people I see doing this. No judgement , it's just now how I use the device.
I couldn't give up my syncing of progress! I love being able to pick up on the Kindle app on my phone if I'm in a waiting room then back to my kindle proper at home.
I'm jazzed to finally have been able to jailbreak my device so I can use KoReader on both the phone and Kindle and keep the same experience.
I've currently got progress syncing through Calibre-Web-Automated, but I'd also tried it via KoInsights which I'm using for syncing reading stats. I'm in the process of migrating to my library to BookLore which also has a sync server.
