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. (This feature is currently in limited mode; contact us for more) Feel free to explore and let us know what you think! Caltech is powered by Vicinia smart enterprise solutions from cntxts Inc.

The clearest difference is ratings volume: PowerFlex at 5.2K against Caltech's 1. PowerFlex also leads on chart position (#152 vs unranked) and iOS requirement (15.1 vs 17.0). Caltech's advantage is rating (5.0 vs 4.8). On price, update cadence, ads and in-app purchases there is nothing between them.
