Developers are free to create whatever they want. That's why we see in Android a huge amount of applications and some, in the opinion of many, a bit useless. Android Wear, Google's operating system for wearable devices also has some apps of dubious utility.
In this application, whose name is Video for Android Wear&YouTube, you can dictate what you want to search, play, move through the video and access more videos. But what is most surprising is certainly Chromecast support. Sliding sideways a couple of times we are able to send content to our Chromecast and view it from there. In short, play YouTube videos on your Android smartwatch.
A somewhat 'crazy' idea by the developer that took place as a video on such a small screen as watches has, even if it has Android Wear; it seems meaningless. On the other hand, we see some use for compatibility with Chromecast because if you are with friends and you want to show something from the watch you can.
We talk about a free application that can be installed from now to test it on your Android Wear. If you really want to play video on your watch, it is important that you have linked to the Bluetooth speakers or headphones. Otherwise you will not be able to hear it.
