After plenty of rumour and speculation, Microsoft has quietly launched its version of Office for iOS—but as of yet there's no iPad version.
The app requires an Office 365 subscription, and allows you to view and edit Powerpoint, Excel and Word files which are stored on the cloud or attached to emails. You can also edit recently used files offline, and create Word and Excel documents from scratch on your device.
The app is available for iPhone and iPod Touch, and requires iOS 6.1 or later. iPad support is curiously absent—especially given that it would be a more natural device for document editing—and the app is currently only available in the US. [App Store via Engadget]
