Early 2015 Microsoft acquired Sunrise Atelier Inc., maker of the Sunrise calendar app, for a rumored sum of $100 million. Come August 31 Sunrise will be no more, something that won’t come as much of a shock as Microsoft said late last year that its Sunrise calendar technology will be integrated into Outlook mobile apps for iOS and Android.

Note: If you’ve been following Sunrise, you’ll remember that the shutdown date of the end of August was announced by the company back in 2015.

Microsoft plans to remove the very popular app from app stores in the next few days, and on August 31 it will be shut down and stop working completely. This is bad news for many who loved the app that reinvented the way “people use calendars on mobile devices”, but at some point everything you liked about Sunrise could be incorporated into Outlook. This probably can’t come soon enough, as Outlook’s current calendar app hasn’t received much love from critics and users.

The Sunrise team, making this possible working alongside the Outlook team, bid farewell in a recent blog post. “No new features. No bug fixes. For us, that’s the definition of a lousy app and it’s not a user experience we want to leave you with. For this reason, we’ll be removing Sunrise from the app stores in the next few days,” said the team. The team shouldn’t feel too bad. Sunrise Atelier Inc. raised $8.2 million prior to the Microsoft acquisition, and its Sunrise app has gained nothing but praise.

The end of summer might look like a poetic time to shut down an app called Sunrise, but the move coincides with Microsoft’s big revamp of Outlook.com – which came out of preview in February this year.

Microsoft has had focused on “reinventing” (the words of CEO Satya Nadella) productivity for some time, and Sunrise was just one of many acquisitions in 2015 that aligned with Nadella’s vision.
