Finally an e-reader where I can set any font I want as the default one, not just those that came with Android or the app. Also, excellent integration with all kinds of dictionaries, Wikipedia, even Anki. Free and ad free, with a modest pro price for some extra bells and whistles with highlight colors, various ways to underline text and such.

Downrated because it still doesn't and can't use fonts that are included in the book. I am still missing a dynamic total page number in bottom status calculated from text scaling, and an invisible brightness slider at the left screen edge. Also it adds an import action to the system for ePub files, but open is enough. You can then import in app.

I just downloaded this because the others I've used have not made grabbing books from your Google Drive easy in the slightest. This was like one or 2 taps of the screen to do so. Automatic 5 stars to me.
