Ratings and Reviews

Good idea, but...


I like the idea but so far I have just gotten alerts saying someone is nearby only to find nobody there when I open the app. Perhaps it should delay the alert until someone has been in range for a couple of minutes.

Very clean, just needs to get popular


I beta-tested this app when it first came about, and I was more than pleased with the overall layout. I'm glad it's taking off, however I'll be even more happier when I can actually find some people to talk to! Great job to the developers though, I'll be keeping this app around because I know it's going to take off.

Awesome Idea

This App is cool. I like that I can send out messages to anyone around. Gonna be even better as more people install and use it. Stoked
