What others are saying
A really cool tool. It is easy to use and comments are easily inserted. Many tools are available for commenting. It's fun that way.
I like to use this tool on my tablet. The app supports free drawing and so I can draw and write directly in the PDF with the pen. It almost feels like pen and paper.
