I am a student, and anyone who has taken a class at USC will tell you that the amount of reading per class is Insane. Aside from the stacks of books per class, there are just as manny article readings. If it were not for this app reading to me during my commute, or while I am working, I do not think I would be caught up on my reading. And my midterm, which I got a perfect score on, was based 90% on reading and about 10% on lecture. I had the free version and it works good. The ads are on a small strip at the bottom, and don't interfere with the reader at all. Yet I am so grateful for my A+ that I upgraded just now to the paid version to support the people who made it. I have not used the paid version yet, but I already know it's worth every penny. I did take away one star became on articles (usually PDF's) that have one paragraph on the right side of the page, and another on the left, the reader will read from left to right, top to bottom. Although there is a gap between the two it will read the first line of each paragraph as one. As one can imagine, this distorts the flow and makes no sense. Yet, While it's not perfect, it's better that anything else I have ran into.
