Football or Eurovision is more fun to watch with others. It’s not the same experience when you’re by yourself. In fact, you're almost never watching something by yourself on TV, there are plenty of people watching it at the same time as you.
This is where Tvtter (Much original, so joke, very wow) kicks in. It syncs with your Swisscom TV and every time you switch a channel you get a “chat-room” for this particular channel, where you can discuss things and vote for things. You can switch the channels right within the app. It's as if Twitter, TV remote and a smart TV had a baby.
You can also see the most discussed shows at the moment, making it easier to choose what to watch.
