How it works

WhisperChat collects your location (longitude, latitude) and a range (in kms) from you, and sends it to the server. The client has to wait in a queue. As soon as another client connects, the distance between their location and yours is calculated and compared with the range that both of them have selected. If the distance between them is less than both ranges, then they’re moved from the queue to a room where they can communicate.
