Google has announced, starting today we’re making Quickoffice for Android and iOS available for free, for everyone. With Quickoffice, you can edit Microsoft® Office documents across your devices, giving you the freedom to work with anyone no matter what hardware or software they’re using. Plus, it’s integrated with Google Drive storage so you can safely access your files from anywhere. Also, if you sign in to your Google Account from the new Quickoffice app for Android or iOS by September 26, 2013, you'll get an extra 10GB of Google Drive storage for two years, which will be added to your account in the next few weeks.
