I think I saw a few other walkie-talkie apps on the market. I think some of them use bluetooth, though, so you have to be near the other person. Anyone know of any other apps like this that are more solid?
I somehow doubt that they use bluetooth, since the effective range of bluetooth is far less than the effective range of the human voice while talking at a normal volume
Usually bluetooth can only maintain a connection over a distance of about 30ft, and if you're trying to stream music or voice over if you may be limited to 6-10ft depending on your hardware. Basically, you'd be better off shouting
