The Verge has learned through several sources close to Microsoft’s plans that the company will release Office versions for Android and iOS in early 2013.
Office Mobile will debut in the form of free apps that allow Android and iOS users to view Microsoft Office documents on the move. Like the existing SkyDrive and OneNote apps, Office Mobile will require a Microsoft account. On first launch, a Microsoft account will provide access to the basic viewing functionality in the apps. Word, PowerPoint, and Excel documents will all be supported, and edit functionality can be enabled with an Office 365 subscription.
