Kast

All you have to do is create a party room and add your friends. One of the most entertaining aspects of Kast is its chat system that you can use to keep in touch with your friends at all times. This feature is very useful if, for example, you're watching a movie together and you want to discuss certain scenes or situations. Kast lets you easily broadcast the content you're watching on your smartphone. Plus, the fact that you can chat via a built-in chat boosts the fun in each of your virtual parties.
