Faro is an app designed to help you find your group when there's no signal.
In crowds, at events, or in areas with no coverage, phones can communicate with each other using their own signal. Faro takes advantage of this so that people nearby can see each other.
You don't need internet or to register. Just open the app and use it wherever you are.
Faro doesn't replace the network: it's a tool for connecting when the network is down.
