Since Microsoft acquired Sunrise last year and began the process of integrating it with Outlook, I’ve been wondering when they’d bring back the popular third-party integrations of Sunrise. That became clear today with the launch of three Calendar Apps for Outlook on iOS – Wunderlist (obviously), Facebook, and Evernote.

Here’s the Outlook team, writing on the company blog:

This is why we are launching Calendar Apps for Outlook on iOS and Android. With Calendar Apps, you can connect your apps—Wunderlist, Facebook and Evernote to start with—to see all your tasks, events and notes from your digital life in one place: your Outlook calendar. By connecting your calendar with a wide range of services, Outlook will be able to provide you with a far better view of your day, week and months ahead.

Those of you who use and love Sunrise will be familiar with this capability. Since the Sunrise team joined Outlook, we’ve been hard at work bringing all the goodness and extra features from their app directly into our calendar to give you a single, powerful app for managing your personal and professional life. Calendar Apps, along with a two-week mini-calendar, three-day view and iOS calendar widget, have already made it to Outlook, with Connected Calendars up next.

Smart move, and something I don’t see Apple doing either. I hope they’ll open up the platform to more services soon.
