A few months ago, Microsoft confirmed that it will bring the standard Windows Phone keyboard to iOS. Today's novelty is not exactly that, but a keyboard is from Microsoft.
The App Store has just Hub Keyboard, Microsoft Garage project.
Sorry, app not found.
Focused on Office 365 users, Hub Keyboard offers integration with documents (stored on OneDrive or SharePoint) and contacts, search, ease to paste copied texts and in the future also translation of texts that already roll on Android, as shown in the video below.
The bad news is that for now Hub Keyboard only works in English, but Microsoft has already promised support for other languages soon. It also only runs on iPhones / iPods touch, without native support for iPads.
