Microsoft has officially announced its acquisition of Sunrise, developer of a next-generation Android and iOS calendar app.

“We are making this acquisition because we believe a reinvention in the way people use calendars on mobile devices is long overdue. Our goal is to better help people manage and make the most of their time in a mobile-first, cloud-first world,” wrote Rajesh Jha, corporate vice president of Outlook and Office 365 at Microsoft, on the company’s blog.

Sunrise’s calendar app has already been downloaded by millions of users, according to Microsoft, and will continue to be free and support a variety of third-party apps and calendar services after the acquisition is finalized.
