Microsoft's one-handed iPhone keyboard is here

Microsoft's one-handed "Word Flow" keyboard has made its way onto iPhones.

This is the second keyboard Microsoft has launched on iOS this month; the first was their productivity-centric "Hub" keyboard.

Both the Word Flow and Hub keyboards have come out of Microsoft's Garage division. Word Flow originally premiered for Windows Phone users alongside Windows 8.1 in 2014, but now iPhone owners can use it too. This string of keyboard releases comes only two months after Microsoft acquired the keyboard-focused AI company SwiftKey.

Word Flow's main focus is on making one-handed use on bigger smartphones more feasible. Here's how it works.
