Zello is a free push-to-talk application for smartphones and PCs. It’s lightweight, easy to use and extremely fast. Better yet, it’s free and will remain free for personal use.
50 million. That’s how many times users have downloaded Zello. Try it on your Android, BlackBerry, iPhone, PC or a mix!
In practice, when you have Zello installed and are subscribed to the Operation American Spring channel, you will hear anyone who talks there. You might be in the middle of checking your email or looking at a YouTube video, it doesn’t matter. And to talk on the channel, press the <F7> key on your keyboard (and let it go after you’ve spoken so that you can hear any response from others). Up to 100 users can share one channel.
Not only does Zello work on a PC but it is also available for smartphones (Android, BlackBerry, iPhone) which effectively turns them into walkie-talkies, provided you have internet access.
Although I have set up an ‘Operation American Spring’ channel, I would imagine that sub-groups would create their own channels eventually, for example ‘OAS-Texas’, which could have restricted access so that they are not bothered by unwanted chit-chat.
