The Zello app is a lightning fast free PTT (Push-To-Talk) radio app that can turn your phone or tablet into a walkie talkie. You can talk to your contacts privately or join public channels to engage in a hot debate as you have a network(even a 2G or 3G is acceptable) or WiFi connection.
The Zello Walkie Talkie app may have made the news and topped the App Store during recent hurricanes when word spread that volunteers were using it to coordinate rescue efforts. The app is emerging as an important tool for search and rescue. But the push-to-talk wide-range communication app is useful in more temperate times as well.
