Zello is a messaging app that focuses on audio over the traditional text messages. Unlike Skype or WhatsApp, which function more like traditional telephones with continuous two-way communication, Zello uses a UI that's more akin to a walkie talkie.

This sort of app is often referred to as a walkie talkie app.

How Does Zello Work?

  1. From your Zello Contacts list, tap the person you wish to communicate with.
