A new version of Adobe Reader Mobile recently arrived at the Apple App Store and Google Play Store— Adobe Reader Mobile 10.4.

Adobe Reader Mobile is a free application available for iPhone, iPad, and Android platforms.

Using Adobe Reader Mobile, you can manage a library of PDFs from your phone or tablet, view PDFs, add notes and comments, fill in forms and more.

There is also a new feature called Cloud Sync which allows you to easily move PDFs from your PC to tablet or phone and keep changes synced.

Adobe Reader Mobile now syncs content with Acrobat.com. Changes that you make to a PDF— adding a comment or filling in a form— are automatically saved back to acrobat.com.

In Adobe Reader Mobile, you can also mark up your document with highlights, sticky notes, a pencil, etc.
