Yesterday, I found this awesome app named "Vortex" and it's everything I wanted the Twitch app to be. An useful main menu that presents you your followed channels and the most played games at that moment. It's the stream page that makes all the difference though, you can finally view the chat in the usual Twitch form complete with all the emoticons! You can also select the "Source" quality and if your tablet/phone can handle it, you can view 60FPS streams and overall an unprocessed higher quality video.
You also don't get Twitch ads and there are no other ads embedded in the app.
Take a look at these comparison screens:

|Neat! You can keep track of chat and video very easily.|
