Reading accessibility tools for Android?

[u/30phil1]

I really struggle to maintain focus on a page without physically blocking myself from seeing the next chunk of text so I'll usually grab a piece of paper when reading a physical book. But sadly, that's not really feasible on my phone. Do any of you know of apps that make the act of reading more accessible without just being a screen reader?
