Zello is a push-to-talk application for smartphones–a walkie talkie app for Android, BlackBerry, iPhone and Windows PC. Push the button for instant, radio-style communication. It’s faster and handier than phone calls, SMS and online chatts. International conversations are free, too.
Talk one-on-one, start your own channel or join one of thousands of existing public channels. Connect globally in 11+ languages.
Check Zello@Work if you want to use Zello on rugged Windows Mobile devices or within a company network.
