It's a really good app... However there's only a few books that has my grade level in it (grade 10) and I can't open my documents in it but even so it's still great reading app it has a lot of features that can help you in learning such as the notes or notebook feature that can put your thoughts in the passages in the books.

Trying to install on tablet running Android 8.1. App installs but freezes on homepage and there is no menu to navigate to epub files. Just get a spinner. I verified app permissions. Installation of app on my Android phone was successful but screen is too small to see the embedded videos. Appreciate any insight.

6/19/2021 UPDATE: Okay!! Now it's works on the phone the way out works on the desktop. Finally. It plays video files inside epub books! Outstanding! Tried it out and changing rating from 1 to 5 stars. Thank you!! 1/10/2021. I had given the app 1 star. Cannot read epub files on Android. Completely useless and I only use it because a paid tutorial I bought said to use it because it has internal video files.

The app cannot open files (zipped fb2) as "open with". It makes a handler for zip files but does not show book contents. Update: I missed all the point. This app cannot open fb2 (anymore? or?...), only epub.

The formula written in the author app is not showing properly in the reader app. Also, the question part does not send the score to the email listed by the reader.
