I need this app to access my textbook for my current course, but of course, as per everyone else’s experiences, it is just useless. I’ve gone through all of the correct procedures, and it still fails to allow me to utilise basic functions, such as highlighting, or even downloading. I don’t think I’ve ever hated an app this much before.

Completely useless. Don't waste your time.

It's a great tool for managing PDF files esp. When studying and needing to highlight notes and make annotations.

Fantastic app that really helps me monitor my intake. Love the recent updates. Would definitely recommend it.
