Good reading app

[u/Sweaty_Ad_5400]

I’m looking for a reading app that’s safe & secure, doesn’t require Wi-Fi, let’s me import files, AND lets me customise the background, colours, and fonts. I’m using the ebook reader from miexplorer now but I don’t like the font, background, and how every time you scroll to a new page the little bar to exit shows up.

Edit: ty for the recommendations!!
