Walkie-Talkie launched with watchOS 5 in 2018 and allowed Apple Watch users to send push-to-talk voice messages to one another over Wi-Fi or cellular using FaceTime infrastructure. Unlike traditional walkie-talkies, it worked over any distance, making it a novel way to communicate without picking up an iPhone. Despite the promise of the feature at launch, however, Apple gave it very little attention in the years that followed, with no meaningful updates across eight major watchOS releases.

Shortly after its debut, Apple was forced to temporarily disable Walkie-Talkie following the discovery of a security vulnerability that could allow a user to listen through another person's microphone without their knowledge. Apple resolved the issue with a watchOS 5.3 update, but the episode did little to build lasting enthusiasm for the feature.

The app's removal has not been officially confirmed by Apple, but users running the first watchOS 27 beta observe that the app is nowhere to be found, with no option to reinstall it.
