Limited functions.
That’s about it when it comes to the flaws of this app. It’s completely usable, and very easy to navigate. It’s main purpose is completely fulfilled. It keeps track of your progress, allows you to copy the text in the book, and make notes. While it doesn’t seem like it allows for any highlighting of text, the notes do include the text. I would greatly appreciate if different modes of reading the text are provided (vertical scrolling, horizontally flipping pages, notes visible at the side (like in google docs), etc.) All in all, this app is completely usable for reading. It would be hard to personalise the app to your own comfort though.
