I was just trying to find _koreader_ on the Play Store, but am not having much luck. What's the actual name, please?

I don't know if it's in the Play Store but you can download the APK directly from GitHub: https://github.com/koreader/koreader/releases

Although Koreader has been originally developed for e-ink devices. I'm not sure how well it has been optimized for normal tablet screens.

Great - thanks for the link.
