Very impractical and difficult to use.
I am a student, and I have been using this apps for two of my etextbooks for the last three years. It is easily the worst out of the 5 different apps I use for my etextbooks. I have several reasons for this. 1. If you go out of the app and then back into it, you will have lost your place in the book and the app will refresh and send you back to the main menu 2. The app is extremely laggy and flat out impractical to be using as a student who needs their textbook open swiftly. 3. Unlike many other ebook apps, it’s very tricky to highlight text and it doesn’t allow you write freehand on the pages, only digital sticky notes which are bulky and a hassle. You might be wondering why I don’t just use the physical copy of the book if it’s that bad, but the school I’m currently attending doesn’t allow that. Besides, these apps should be up to a higher standard.
