It is only with a $99 yearly Office 365 subscription that you can use the complete Office suite on iPad. While the PowerPoint, Word and Excel apps are free to download for iPad users, they are only good for viewing files, unless you have a subscription for Office365. It’s not the functionality of the apps that users have to take with a pinch of salt but rather the limitations. While Microsoft has delivered some fine Office apps for iPad, it has fallen short of user expectations. Microsoft Delivers Office for iPad But Falls Short of Expectations And an account with a subscription can allow you to really get creative on an iPad device by making use of the plethora of options available via the Home, Insert, Slide Show, Transitions, Shape and Review tabs. What’s good about this app is that it allows users to render slideshows like the desktop version of PowerPoint. This app like the others supports native file formats. Something else that works without a subscription is the ability to freeze panes. The View tab is by default the only active tab and you can show or hide the Formula Bar, Headings, Gridlines and Sheet tabs. Like the Word app, Excel too has view only capability, unless you are an office 365 user.
