(Note that the app’s name is pronounced “Office Squared,” and that the “2” appears as a superscript when you’re searching for it on the App Store.)
Office2 also provides integration with Google Docs, letting you edit Google Docs documents and spreadsheets from within the app. You can also access, move, and delete documents stored in Google Docs, iDisk and any WebDAV server.”
