Good app

As a student I wanted a good PDF reader that would allow me to annotate notes, highlight things, etc., give me the functionality and freedom to alter pdfs as I see fit. To that end, this app has been tremendously helpful. I cant figure out how to erase things besides using the undo button but that hasnt been a big problem. I would recommend this app to students looking for a good PDF reader that is free.
