This is how the Walkie-Talkie function of watchOS 5 works

One of the few novelties of watchOS 5, not related to sports activity, we find it in the walkie-talkie function, a function that allows us send audio messages between Apple Watch. The operation of this function is very similar to that currently offered by messaging applications, applications that allow us to send audio messages.

Walkie-Talkie works like audio messages through FaceTime, instead of recording messages that are later sent, so they leave no trace on any of the devices, being a very safe way to have a conversation, without the records being stored neither on the phone nor on the device.

The operation is very simple, since we only have to open the application, select the contact and press and hold the Talk button to send the audio to our recipient. As long as the recipient has the app open, the audio will automatically play through the device's speaker. If not, you will receive a notification to open the application and be able to play it.

The initial communication, that is, the first audio to be sent, it may take longer until the device with which we want to communicate is located. Once the connection is established, communication will be instantaneous.

The functionality that this application offers us, is very similar to the one offered by applications with this functionality, but unlike these, Apple does not record the audios to send them later, but a kind of one-way call is established between the sender and the receiver, so the audios are not stored on any server and are recorded.

If you are users of a first generation Apple Watch, you should know that you will not be able to enjoy this function, as Apple has left the original Apple Watch without updates, three years after its launch.
