Fantastical is a calendaring app for the Mac that makes entering appointments quick and easy. The idea behind Fantastical is that you can enter your appointments using natural language. Open up the entry dialog via either the toolbar or a key combination, and just type naturally. Fantastical takes care of the rest. For example, if you type “Meet with Joe at the office on Thursday at noon,” Fantastical will plug all of the appointment details into the correct slot in a calendar entry, using a slick user interface.
