Office for iPhone and iPad
Microsoft Office for iPhone and iPad lets you view, edit, and present all your Word, Excel, and PowerPoint documents right on the go. The Office for iOS apps are free downloads and include the editing and presenting functions. Some editing features require an Office 365 account. Office for iPhone and iPad are meant to work with Microsoft OneNote and SharePoint products, but also give you other save and share options as well.
In many ways, the lack of Office on iOS — and indeed, touch Office on the Surface as well — was just another painful example of Microsoft failing at mobile. Indeed, it took Microsoft so long to launch office for iPad — almost 4 years after the original iPad launched — that free alternatives like Apple's iWork and Google's Docs have had time enough to catch up in most ways that matter to most users.
Since Office initially launched for the iPad in the spring of 2014, Microsoft has added more features and taken away some of the subscription required restrictions that were initially in place. Office was also officially given support on the iPhone which brings the entire suite to iOS in its entirety.
For some users, Office may have been too little too late. Many iOS users has simply moved on to another platform or service such as Google Drive or iWork. For enterprise users, however, for those for whom there can be no alternatives, then Microsoft Office for iPad is more than a must have. Those are the ones who are going to get the most out of Office for iPhone and iPad, and the full-on touch versions of Word, Excel, and PowerPoint.
