Sunrise has quickly become the calendar app of choice for some people, and for good reason. Besides its straightforward interface and support for all your social networks, it's one of the few truly multi-platform schedulers you can find -- as of this May, it can run on Android, iOS and the web. It hasn't had a native desktop app, however, and the company is rectifying that by launching Sunrise for Mac. Not surprisingly, it's more than just the iPad app writ large. In addition to all the advantages that come with more screen real estate, you get both a mouse-friendly interface and native OS X notifications; there's also a complete offline mode if you need to review your itinerary on a flight without WiFi.
