The IAFF Pro-Calendar iPhone App was designed based off our popular 48-page calendar/organizers. We have been making calendar/organizers for fire fighters for over 15 years. Now, we have taken all of the best features from our calendar/organizers, and put them into an app. Now you can manage you shift schedule, track trades, vacation, and even manage all of your personal appointments, plus much more. The IAFF Pro-Calendar App will be the last calendar you ever need.
