Comments on Episteme: PDF & eBook Reader for Android
★★★★★UK Karthik· Mar 21, 2026
Best PDF book reader Wish can you add sepia reading mode. Which can make it complete all-rounder app for long read
★★★★★Nester 00· Apr 22, 2026
Very, very promising! I've been using separate "simple" readers for pdfs and pubs because I don't want the granular metadata editing stuff and this strikes a good balance between simplicity and just enough features without all the bloat. Can you add an option to adjust the margins in the future? Literally that's the one thing that's missing for me!
★★★★☆Mrk Concepcion· May 5, 2026
I hope there's an option to read all Annotations/Notes without going back to the chapter where you annotate or noted a phrase. It's like reading all your Annotations/Notes in one single page. Thanks
