The app then takes that text and sets all the proper functions in the calendar, significantly faster than trying to enter all that information into a traditional calendar app. The app is aware of things like time zones, and the parser is very good at setting up repeating events with odd cycles like "every third week", something that the standard iOS calendar can't always deal with. It also has an in-app map view if locations are entered, and users can send that address to Apple or Google's Mapping apps.
