Why can’t I add a schedule to my calendar? – Magic Hour Review

This app can display the magic hours for my current location, but I cannot add a schedule entry into my iPhone calendar so I can plan a shoot. It requires me to add a location first, then and only then will it let me put a magic hour event in my calendar. Why???? Why does this app display a background photo which has nothing to do with my current location? Example: I selected Huntington Beach, California. The photo this app shows for this location is some desert scenery. Why????
