Hello Mobile

Hello is a private, real-time location network for Family and Friends. It's real-time motion and location with context using real place names like Starbucks or Facebook.

A pin on a map gives only a partial picture of your location. Understanding where you are, who you're with, where you're going and where you've been is a more useful and complete experience.

We build the real timeline of your life, powered by motion as you walk through your day. Your motion state - walking, running, driving and biking is shared with Family and Friends in ways no one has seen before.

Due to privacy concerns no one has built a comprehensive system to find, track and navigate to people in the same way as places. We've developed a discovery social experience where users share motion and location with context in fun, useful ways while maintaining privacy.
