Adobe updated its Reader app for iOS, and what was a good PDF reader is now an excellent tool to annotate and sign documents. As luck would have it, I needed to add a note and sign a PDF file that was sent to me via email today. This rare occurrence gave me the opportunity to check out these new features using the iPad version of the Reader app.
The latest version of Adobe Reader has several new tools for marking up a document including a freehand drawing tool, a highlighter, strikethrough, and underline. You can take a page in a PDF document and use these tools to point out spelling errors, highlight important text, mark sections for deletion and more. If you need to add a longer correction, you can even attach a sticky note
