I have to disagree on best in class. Wunderlist was a pig on desktop, and they killed the desktop app entirely for Windows7. I far prefer todoist.

I also think Tempo is head and shoulders above Sunrise after spending significant time with both. I can't find the value in a calendar app that lacks the ability to dial a conference call number in 2015.

Unfortunately you'll only be able to use Tempo until June 30th. They've been acquired by Salesforce and are discontinuing Tempo (at least in its current form…)
