Is there a way to get colour there? B&W bums me out... I'm on GrapheneOS so have MoonReader (install google services, install, disable network on it, uninstall google services, and you're good) but ebooks is one of my major use cases on mobile and everything FOSS sucks in comparison...
I like green on black on my phone, nice screen, good for the eyes. I'd love to sync between that and my kobo, but not happening at the moment. Currenly read new things on the kobo and old faves on the phone, it's fine, but could be better...
