Full Slate integrates with Google Calendar so you can make or change appointments in either application, and the other stays up-to-date with real-time, two-way sync. Or you can keep your personal and professional calendars separate and still see everything in one place.
Full Slate syncs with other calendars and devices too, including iPad/iPhone, Android, iCal, Outlook and other programs that publish an iCalendar feed or webcal. Full Slate can even overlay meetings or events from an external calendar on your schedule and automatically make those times unavailable to clients.
