Microsoft is merging two of its most popular mobile apps into one: Outlook email and Sunrise calendar. Outlook has always been a favorite among email users while Sunrise rose to fame for being both free and feature-packed. Combined as one, Microsoft is hoping the move enables users to more seamlessly glide between emailing and calendar tasks.

The result isn’t really a huge departure from what Microsoft currently offers in Outlook, since Outlook already has your calendars built in. Instead, it’s more about refining navigation within the app while additionally bringing in some features from Sunrise.

The biggest change is that the sun is setting on Sunrise. After Microsoft bought the calendar app just this year, the company is already pulling the plug on it.

Microsoft’s devouring of our favorite mobile apps continues today with the acquisition of 6Wunderkinder, makers of popular task management app Wunderlist.

The buyout, which comes just four months after Microsoft acquired Sunrise, will help the software continue its mission to reinvent productivity in a mobile-first world, it says.

What’s better than buying one of the most beloved calendar apps for mobile? Buying two of them.

After snatching up Acompli in December, Microsoft has acquired Sunrise, another popular calendar app on iOS and Android.

Sunrise, one of the most popular third-party calendar apps for iOS and Android, released a Mac version today.

It looks a lot like the existing mobile app and has many of the same features, including the functionality that sets Sunrise apart: direct integration with services like Evernote and Facebook.

In this era of heightened security fears, when headlines routinely shout about hackers stealing millions of personal records in a single digital heist on some of the nation’s biggest companies, you should never be handing your Apple ID and password over to anyone who isn’t Apple. Yet that’s just the permission that the new Sunrise calendaring app asks when you first load it up, and not only is there no rule against apps doing so in Apple’s internal guidelines, but Cupertino’s actually awarded Sunrise with a coveted spot in the “Featured” section of the App Store.

When Sunrise Calendar got its big iOS 7 makeover last fall, it solidified itself as one of the leading third-party calendars in the App Store. The biggest thing it was lacking was an iPad version—well, until now. Released last week, Sunrise had made its way to the iPad, and it’s great.
