Microsoft is acquiring keyboard app SwiftKey for roughly $250 million, according to the Financial Times. Microsoft declined to comment on the deal.

Based in the United Kingdom, SwiftKey is an app available for iOS and Android that uses prediction technology to help you write faster. SwiftKey claims users have saved nearly two trillion keystrokes and more than 23,000 years in combined typing time using its software.

SwiftKey is installed on more than 300 million devices, however it isn't available for the Windows Mobile platform.

The $250 million price will be one of the biggest recent exits for a UK-based tech company, according to the Financial Times. According to its most recent annual report filed at the end of 2014, SwiftKey had sales of roughly $12 million.

SwiftKey will join a list of software acquisitions under CEO Satya Nadella: Acompli, an email app, Wunderlist, maker of to-do list software, and Sunrise, a calendar app.
