Mobile appfreeglobal

Sifter is a hyperlocal iPhone chat app where rooms are anchored to real-world geofences like concerts or campuses, so only people physically present can see or join, with no global feed or persistent history. It's aimed at people who want location-authentic chat without remote lurkers diluting the conversation.
