Apple showed off a major new app coming to watchOS 5 later this year, called "Walkie-Talkie." Using the app, Apple Watch wearers will be able to send quick voice messages to friends and family members by speaking into their Apple Watch, similar to real Walkie-Talkies.
To start using the feature, users will have to allow a connection to one another in the app. After, it will show a scrolling list of connected friends, which you can tap, speak your message, and send to their Apple Watch. Apple said the main purpose of Walkie-Talkie is to act as a middle point between sending a text message and calling someone on Apple Watch.
Additionally, a watch-to-watch connection will work over cellular and Wi-Fi.
