You pay $100 per year and you gain the ability to download the latest desktop versions of Office for your Windows and Mac PCs. Office 365 is Microsoft’s subscription service for Microsoft Office. Microsoft now provides “Office Mobile for Office 365 subscribers” apps for iPhone and Android, which you can install from Apple’s App Store or Google Play. RELATED: What's the Difference Between Office 365 and Office 2016? It’s designed so you can view your Office documents and perform some basic editing on the go, not to function as a complete productivity solution. Of course, Office Mobile is a simplified version of Office for mobile phones. Unlike the versions of Office Mobile for iPhone and Android phones, Office Mobile for Windows Phone is completely free to use and doesn’t require an Office 365 subscription.
Windows Phone comes with a free version of Office known as Office Mobile. That said, the version of Office that comes with Windows RT devices is almost the same as the full version of Office for Windows 8, and it’s included for free. For example, macros aren’t supported at all. Windows RT tablets do include a free version of Office, but it’s a bit limited.
