Ask HN: Best Android e-reader apps?

Android apps optimized for e-ink usage. I hate using the browser (and it drains my battery) so no web apps.

I'm using Materialistic to browse HN but it really isn't optimized for e-readers. Anything that requires scrolling sucks.

Tachiyomi is great but it's a little cumbersome to use too. I couldn't find an e-ink mode but I disabled animations and more stuff.
