So, I just got myself a new phone and its S7duo. It doesn't have any apps that can open Epub, so I went to play store and got myself 2 apps off/online from the top rankings. And those were sooo slow. I'm so used to apple's Book app It's very fast doesn't reload every time when you go in and even when it does it's fast as hell. But those that I found on play store they load like a turtle or a snail. Which means I just haven't found the right ones. I PREFER A FAST APP THAT LOADS FAST AND IT'S OFFLINE, bec I do my readings offline.
