You can be like Dick Tracy with a 2-way radio on your wrist! From an article by Megan Rose Dickey in the TechCrunch web site:
“At Apple’s annual developer conference today, the company showed off a new walkie-talkie feature for Apple Watch. The app is uniquely called Walkie-Talkie.”
“The first time you use it, you send a request to your friend, who can then accept or decline it. If they accept it, you can then walkie-talkie them at any time. This watch-to-watch connection works over cellular and Wi-Fi, and enables you to send short voice messages to friends and family with an Apple Watch. Once you press to talk, your friend will feel some haptic feedback and then hear your voice immediately.”
There’s more info in the article at https://techcrunch.com/2018/06/04/apple-watch-gets-walkie-talkie-mode.
The person you wish to talk with can be 10,000 miles away or even further, as long as both parties are within range of either wi-fi or the cellular company’s network. That’s a lot better than those CB-style (Family Radio Service) walkie-talkies the kids use! Voices are digitized and all data flows back and forth across the Internet.
I don’t think I would want to leave the watch walkie-talkie on all day and especially not all night. I don’t think I want to be all that available. Yes, that would be a privacy issue.
