Event-IS your go to app for organizing coordinating an event in real time.
This app is your one stop, solution to communicating with people coming to your event in real time i.e give them updates about parking, or start time or any other relevant information they need to know.
So instead of messaging each attendee and repeating yourself, your friends/acquaintances or just general people attending your event can get information or updates about the event in one central app. This app can act like a real time Yelp for various big events too, just upload your event, get the Tag and share with your friends and see what they saying about the event.
