Office for Android tablets was released on January 29, 2015, following a successful two-month preview period. These apps allow users to edit and create documents for free on devices with screen sizes of 10.1 inches or less, though as with the iPad versions, an Office 365 subscription is required to unlock premium features and for commercial use of the apps. Tablets with screen sizes larger than 10.1 inches are also supported, but, as was originally the case with the iPad version, are restricted to viewing documents only unless a valid Office 365 subscription is used to enable editing and document creation.
