It's just enough for quick get-togethers and nothing more! Create an event by simply answering who, what, when, and where, and receive notifications as invitees respond in or out. Organize friends into invitee groups for quicker event creation, communicate with invitees using event messages, share photos and videos from the event, even get the weather forecast of upcoming events. Perfect for girl's night, sports roll call, and any other "ad hoc" social event where you just need to know who's attending with as little hassle as possible.
