Doodle

Doodle is the simplest way to schedule meetings and events. Ditch the endless rounds of email ping-pong, trying to figure out when people can meet. Instead, create a poll with all the date/time options you want, let everyone choose their preferences and within minutes you've scheduled the best possible date. Doodle is the preferred scheduling tool for millions because of their ability to set up time with the people you need to in just a few clicks. Their Bookable Calendar allows you to automate your schedule, so you can focus on the things that matter to you. Their headquarters are in Zurich, but they also have offices in Atlanta, Berlin and Belgrade.
