    Zello helps people stay connected with instant live conversations. Think walkie talkie-style Twitter -- except it's not just two-way, it's multi-way with up to thousands of people in a conversation. Zello apps for iOS, Android, Windows Phone, BlackBerry and Windows PC connect people with their neighbors, colleagues and others around the globe.

    It’s a vast network for the original social media: voice. Welcome to social radio.

    ZelloWork is an enterprise solution that allows organizations to create secure, private and managed networks that exceeds their 2-way radio needs. ZelloWork has a web-based admin console to manage users, groups and settings. It works with traditional 2-way radio, but also with users'​ iOS, BlackBerry, Android and Windows Mobile devices. All they need to do is load Zello, sign in their ZelloWork account and go.

    The hosted business solution spans multiple industries, including freight and trucking, cell phone carriers, security and government, air and ground transportation and emergency medical services.
