Calendly is a desktop application that allows people to schedule appointments right into my calendar without having to go back and forth via email five times,” says Cameron Herold, a business coach and founder of Phoenix-based COO Alliance.

It’s got the usual calendar features—color-coded events and the option to make a meeting recurring—plus a few extras, like a limit to the number of meetings people can put on your calendar each day and time zone detection so everyone’s on the same page about when the meeting begins.
