A city full of strangers, made smaller.

Phones made it effortless to talk to people far away, and somehow harder to meet the ones nearby. You can have a thousand contacts and still find nobody free to get chai on a Tuesday evening.

There is a well-documented reason friendships form the way they do. Researchers call it the propinquity effect: the strongest predictor of who becomes your friend is not shared interests or personality — it is simple physical closeness and repeated chance encounter. People become friends with whoever they keep running into.

Cities quietly broke that. Neighbours don't meet, and the person two streets away who plays the same sport, studies the same subject or keeps the same hours stays invisible forever.

You say what you're up to and it reaches only people inside the radius you choose. You see who is genuinely around you right now. You find the café, ground or park worth meeting at — and you go. That last part is the whole point: the app succeeds when you close it and meet someone in person.
