Kevin Lynch did a good job on stage today at WWDC going over all the new features for Apple Watch which are coming later this year with watchOS and one of those big features, was Walkie Talkie. Apple Watch Series 3 includes integrated cellular support for a 4G LTE connection, and this works great with the new feature which as the name suggests makes the Apple Watch behave like a traditional Walkie Talkie device, this works between watches over WiFi or cellular.

The app allows two Apple Watch users to instantly converse, anywhere in the world. Between each voice clip is played, there will be a haptic buzz from the taptic engine then the voice will play.
