The Caltech app provides services to the network of users that are somehow related to this physical campus. You have access to the campus news and events and can also view Zoom events in the App. A key element of this system is for users to access smart maps of the buildings and locate/navigate themselves even indoors where GPS does not work! You can search for places that are by now marked in these buildings for example restaurants, cafes, WC, elevators, etc. You can also navigate yourself to any of the places of interest.
