You install Chirp, and they install Chirp - pair together and track away in real time, with place alerts, messages and more!
Once you install the Chirp GPS app, you simply connect with your friends, family, and others by “pairing”, or by sending them an invite using any method you like. Pairing, or inviting takes just seconds, and once you are paired with someone, you can track them, send them messages, get directions to them, and all of the other benefits Chirp GPS has become famous for.
