WalkieTalkie is a full iOS8 app template, using the new Multipeer Connectivity Framework. Using only WiFi or Bluetooth, connect to nearby devices and voice chat with them! Very simple to use interface with only three buttons! Turn your phone into a walkie-talkie and talk free with everyone.
You can also set the connection mode, to either auto/manual, so you can connect automatically or not to nearby devices.
Moreover, you can start a text chat with the connected devices.
