Ticketbud
The Ticketbud Organizer helps you manage your events and sell tickets right from iOS. Browse all of the events in your account, check in attendees, and view sales information. Ticketbud uses the camera on your device to validate the Ticketbud tickets you have sold or given away and also to check-in your guests in real time.
