For years, the standard in editing Word documents on the move has been QuickOffice. Today, the app/service has gone free for anyone who has a Google account. The universal app download (version 6.1.0) is available now and is compatible with any iPhone, iPad or iPod touch running iOS 5.0 or later.
As an added bonus, if you get the updated app and sign in before September 26th, you’ll get an extra 10GB worth of storage for your Google Drive account for free.
