80%

of Gen Z report feeling lonely

Your city is full of life you'll never see. Social media shows you strangers 3,000 miles away. Google Maps shows restaurants. Nothing shows you what's actually happening on your block right now.

The average person now has only 2 close friends U.S. Surgeon General declared loneliness a public health crisis

A live social and local map of your city

Discover what's happening, stumble into serendipity, and explore local businesses — all on one map.

Social apps moved away from location.
That was a mistake.

Location is the one constraint that creates serendipity. The best connections happen because you're in the same place at the same time.
