I performed a bit of an experiment this week. At the the FGS conference in Springfield, Illinois, a couple of my friends and I used the Zello (rhymes with “hello”) app on our iPhone, iPad, iPod Touch, Android, BlackBerry, or Windows cell phones to keep in touch with each other. Of course, we could have simply called each other on the phone or sent text messages to each other, but using a walkie-talkie app offered several advantages.
Walkie-talkies are a perfect way to keep in touch with friends or to find friends who may be somewhere in the crowd or back at the hotel. I have experimented with several walkie-talkie apps and have settled on Zello as the one that works best for me.
Best of all, Zello is FREE for personal use. Yes, you probably already have a free walkie-talkie. Well, I guess technically it is not really free but rather is available at “no extra charge” as you have already paid for the phone. You probably will find other uses for Zello after you return home as well.
