Whoozin is a free RSVP online tool that helps you track "who's in" for your group`s meetings or events. Ideal for staff meetings, sports teams, networking events and social clubs. Whoozin makes it easy to notify participants and track attendance for all your events and meetings. Existing invitation applications in the marketplace, such as Evite and Facebook, have various limitations. Facebook can only send invitations to your FB "Friends". Other sites are littered with ads, are excessively party-focused, or charge for all but the basic service. Whoozin is full-featured, ad-free, and free to use. In addition to RSVP events, Whoozin supports "online registration"- so that the creator of an event can share a link to the event page where anyone interested can sign up to attend. Most significantly, Whoozin excels in the delivery of these services to groups whose members meet regularly. It is the ideal tool to track who is coming to recurring events such as book clubs, league sports, game nights, business meetings, and networking events.
