Early action is an admission option that does not bind you to attend an institution if accepted.  Early action applications are usually due in early November, with notification in December.  Because early action is non-binding, in nearly always makes sense to apply this way to schools on your list assuming:

• You're a competitive applicant
• You don't need fall semester grades to enhance your candidacy
• Applying early doesn't actually hurt your odds
• The terms and conditions of the early admission programs ranked higher on your list don't prevent you from doing so

College Kickstart takes care of this for you automatically when you create a plan, so all you have to do is rank your list of schools in order of interest.
