Note: This review rates the full version of Documents To Go. It also touches on the limited free version.
Your Android phone may not have the most ideal screen size for drafting manifestos or multipage spreadsheets, but with the right app it'll do in a pinch. Documents To Go supplies the basic tools for editing Word, Excel, PowerPoint, and PDF apps, and creating new documents from scratch. Password protection, word count, find-in-page, and formatting tools come in the bundle, though unlike its main Quickoffice competitor, Documents To Go doesn't offer remote access to online files like Google Docs.
The free, read-only version shows off the contents of Words and Excel documents stored either as an e-mail attachment or loaded onto the SD card. DataViz aggressively uses the app as a lure to upgrade, prompting you to purchase the full version any time you select a premium feature--which is pretty much all of them, including ascertaining a document's word count and searching for a specific word in a read-only document. If you're truly only interested in reading and not editing, the sales pitch gets old.
