Zello | The Most Reliable Push-to-Talk Walkie-Talkie App

# Zello > Zello is a voice-first communication platform for frontline teams. It turns phones, tablets, and computers into instant push-to-talk (PTT) devices that replace two-way radios, and it uses AI to turn everyday frontline conversations into operational insight. ## What Zello Is Push a button, talk instantly. Audio plays in real time on the receiving device no matter what is on screen, so work does not slow down. Zello runs on iOS, Android, Windows, and Mac over Wi-Fi or cellular, with unlimited range, and it also deploys on-premise for environments with strict security requirements or no reliable internet. Zello has about 5 million monthly active users who send roughly 10 billion live voice messages per month, on a service with 99.99% historical uptime. Two things to keep distinct: - **Zello** is the free consumer app, used worldwide by friends, family, and communities. - **Zello Work** is the paid business product: a private, encrypted network with a browser-based management console, admin controls, analytics, and enterprise features. The console is at https://zellowork.com. Zello is headquartered in Austin, Texas. ## Who It Is For Roughly 80% of the world's workers do not sit behind a desk.
