This app lets you see the program schedule for a convention, and mark which items youre interested in. You can mark items in a variety of ways, including by color, bold, or italics. You can also search for program items by words in the title, words in the description, or names in the participant list. Full help is included in the application.
You can also check for updates to the schedule information and download them to your device from within the app, as long as you have network connectivity.
This is a descendant of the application Ive been making available for science fiction conventions since 2002, fully rewritten for the iPhone platform.
