Союз is an Android app that allows you to watch the Orthodox TV channel "Union" and its music channel "MuzSoyuz." The TV channel is a family-oriented channel that promotes traditional moral values and the rich history and culture of Russia. It has been broadcasting since January 31, 2005. The music channel was launched on the same day in 2015.

The app is easy to use, and the interface is simple and straightforward. You can watch both channels live and catch up on missed episodes. The video quality is excellent, and the sound is clear. The app is free to download and use, and it doesn't require any registration or subscription. However, the app doesn't have any subtitles or closed captions, so it may not be accessible to everyone. Overall, Союз is a great app for anyone interested in Orthodox TV and music.
