Need recommendations on good ebook reading app in phone.

Hey y'all i recently started reading books and ebooks. in laptop its easy to adjust whatever size and text and apply whatever color i want as the theme using extensions but when it comes to mobile app. it kind of becomes hard to read little letters and themes and that too when you have pdfs. i mostly read in the night so im looking for a comfortable app which can work in dark theme. hides the dtatus bar as well.

pls give me the best ebook reading apps you are currently using on phone.
