After acquiring the app over a year ago, Google has just announced that Quickoffice is now free for everyone on both Android and iOS. The app, which is optimized for both phones and tablets, lets you edit and view Microsoft Office documents that are stored locally on your device without compromising formatting. The latest versions now let you work on documents that have been saved to your Google Drive as well, which is a huge deal for anyone that is used to dealing with Google Docs.
Better yet, if you install Quickoffice from Google Play by September 26th and link up your Google account, you'll be offered an extra 10GB of Google Drive storage for two years. This is a great service, and we're going to assume that we'll continue to see more Quickoffice and Google Drive integration going forward.
