Samsung has released the app WalkieTalkie for its branded smartwatches.
What it is
It is a program that allows you to use the watch for two-way voice communication. The app is only available to Galaxy Watch 4 and Galaxy Watch 4 Classic owners. So you can't run WalkieTalkie on a smart-watch with Tizen.
You can use the WalkieTalkie app for quick voice messages with your contacts. In addition, you can create channels in the program, which will participate in several users at the same time. By the way, you need a Samsung account to use WalkieTalkie.
Where to download
The application is already available on Google Play Store. The program weighs 23 MB.
