wheriz allows you to manage easily your geo-localized agenda, share it with your people in a collaborative environment and synchronize it with third-party applications and websites in a fully interactive graphical interface. The website is open freely to any user who wants to have always their agenda available, track the agendas of their buddies or the events' calendars from groups and to forecast future coincidences. Any kind of result can be exported to any open standard format (iCAL, RSS, XML). The premium users are able to create and manage groups. The most outstanding uses of the groups are two: to become a new channel to promote their activities and to coordinate internally the plans of their human resources. wheriz keeps a complete privacy of the content by using a tagged visibility system and only shows information of your interest (your contacts, your subscribed groups and your managed groups). Currently wheriz has an automatic synchronization with Facebook through an application that updates the status of the user in Facebook. External websites can integrate wheriz widgets.
