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.
