Not functional
Files transfer doesn't work, so you can't actually get files into the app to read them. They show in iTunes, they don't show in the app, so clearly there is a programing issue making this useless. Also, the toolbar icons are very low res and look horrible, at least one of the buttons does nothing, bookmarks seem to not have a purpose as you can't access them (but you can add them repeatedly, or say it says…), and most of the tools say they can't be used on the help file because it's read only. Unclear if they would work on a normal pdf since you can't get any files into the app.
