You can get the free Quickoffice app on Google Play and in the App Store. Simply sign in with your Google Account to start editing Microsoft Office Excel, Word and PowerPoint files on your iPhone, iPad, Android phone or tablet. Quickoffice is integrated with Google Drive so you can safely and easily store and access your files across devices. Users who currently have Quickoffice for Google Apps for Business can update their app to the new version and will notice a new icon.
You’ll also see a number of new features including the ability to create .ZIP folders and view charts in Excel and PowerPoint files. Plus, the new app works across devices so you don’t have to worry about installing separate versions anymore when you go from using your phone to editing on your tablet.
