What is Signal Spy?

Signal Spy started as a companion app for Google Fi (formerly Project Fi) called Fi Spy. It provides information about your connectivity via cellular and WiFi connections. It also gives you the ability to control that connection via dialer codes and monitor your connections with a history log. We also provide quick links to Fi communities. That is where we started, and we've made our features compatible with more carriers in the US and worldwide!
