I am already using Google Calendar, Outlook, Apple iCal or Entourage for Mac. Why do I need Tungle?
A calendar is a great place to keep track of your meetings once they’re booked, but they don’t do much to actually get the meeting booked. That’s where Tungle comes in. Tungle integrates with your calendar, turning it into a full scheduling service that helps you get meetings booked, not just hold the meeting details.
