Gate5 is a technology company specialising in location-based applications for mobile terminals and the Internet. For the web-based part of Gate5's product family, preview developed an interface concept that allows the configurations to be tailored exactly to the respective product. The Guide5 mobile application doesn't simply offer up-to-date information about top locations and events in the selected town or city, but also the opportunity to locate, communicate with and arrange to meet friends. A dynamically navigable card with bookmark, search and routing functions allows the users to find their way around easily on arrival at the location. Some of the Guide5 functions were implemented in »Falk City Guide for Pocket PC«.
