When it comes to annotating and reviewing PDF documents on the iPad, iAnnotate PDF ($9.99) is my go-to solution. If there’s an option to download a .MOBI or .EPUB ebook or .PDF version of a book, I always choose the latter because of what iAnnotate allows me to do. The tools and features in this iPad-only app are ten times more powerful than Apple’s iBooks for highlighting, bookmarking, and reviewing annotations which makes it perfect for students, writers, or anyone who needs to mark up text as they read.
