AppAdvice has teamed up with 9 Square, our latest AppAdvice Daily podcast sponsor, in order to offer you a chance to win a copy of DocAS – Annotate PDF, Take Notes and Reader ($5.99) for iPad.

DocAS is a powerful productivity and business app that allows you to create, read, edit, and share documents while on the go.

DocAS allows you to import files from a wide variety of sources, including your home computer via Wi-Fi or iTunes File Sharing, Dropbox, Box, Google Drive, email, FTP, and WebDAV. Once your files are imported, you’re able to organize them within folders and sub-folders, and merge, clone, sort, and rename them. DocAS allows you to view a whole bunch of different file types, including Word, Excel, Powerpoint, RTF, text, Numbers, Pages, and Keynote, but where it really shines is its handling of PDFs.

Annotate.

With DocAS, you’re able to view PDFs in full screen mode, search for text, create bookmarks, and jump to specific pages. You’re also able to add and highlight text, add images from your library, attach sticky notes and voice memos, insert entire new pages, and add custom graphics.

You can also just create a PDF from scratch and utilize DocAS as a powerful note-taking app. It includes a variety of font sizes and styles to choose from, 17 paper styles, copy and paste support, and, if you’d rather take handwritten notes, wrist guard support.

Of course, no productivity or business app is complete without a handful of ways to present and share your content. DocAS includes a full screen presentation mode, AirPlay support, AirPrint support, VGA and HDMI out support, the ability to email notes and documents, and the ability to upload documents to Dropbox, Box, and Google Drive.
