Cortana is not the only Microsoft-made feature that will be coming to the iOS as the company is looking to port the Word Flow keyboard from Windows Phones onto the iPhone.
In an e-mail sent to participants of the Windows Insider program, Microsoft is currently enquiring if they would like to beta test the feature on the iPhone. Said e-mail has stated that the Word Flow keyboard will be making its way into the App Store eventually, but Microsoft will first be hosting a beta in order to iron out the kinks for Word Flow.
Another interesting thing to note is that Microsoft stated that they will be working to extend Word Flow onto other platforms, meaning that Android support is a real possibility. Whatever the case, it seems that Microsoft is trying to expand its reach outside of its own ecosystem.
