Have you ever sat in a bar during a local game or something but you can’t hear the audio because the people are either cheering too loudly or there is just too much noise to hear anything? Well for those situations, yes there is an app for that too, you should consider Tunity. All you have to do is scan the image on the TV while it is muted. The app will locate the channel and play the audio via your phone. So now you have your image just like everyone else but with the added audio coming from your phone. Pretty cool eh?
