Alas, Sunrise is gone. Or it will be soon. The lovable calendar app — whose secret was its simple and seamless interface, and its ability to play well with third-party apps — will continue to function, but only until a few more of its features are transferred over to Microsoft Outlook. (Microsoft bought the company in early 2015.) Which means Sunrise users, if they haven’t already, should be shopping around for a new calendar app. Here are four alternatives.
