Roam is a free Android app developed by Metablox that provides users with access to decentralized WiFi through OpenRoaming. By generating a decentralized ID (DID) within the app, users can seamlessly connect to over a million WiFi hotspots without the need for traditional passwords or usernames. The app revolutionizes authentication by utilizing DIDs as login credentials for WiFi access, offering a convenient and secure method for connecting to networks.

Additionally, Roam features an access point viewing map that allows users to locate and connect to available WiFi connections in their vicinity. This feature enhances the user experience by providing real-time visibility of nearby WiFi hotspots, making it easier to stay connected on the go.
