Do you 
often find muted TV or TV with sound but since the surroundings are too 
crowded with people, you can't hear the TV? Be it on gym, train 
stations, bus stations, food courts?

With Tunity app, you will be able to hear those "muted" TV as 
well as setup a "personal volume" that is louder for your grandparents, 
so while everybody is enjoying the shows with normal volume so does your
 grandparents with their personal setup.
All you need to do is open the app and scan the TV.
The
 app will then detect and stream the audio to your phone so that you can
 watch the TV on the TV and hear the sound on your phone.
This
 technology, however, requires the TV to be setup with the Tunity TV kit
 in order for the Tunity app able to stream the audio to your phone.
Just now, when I tried to request the Tunity TV kit 
by registering, the registration form return me error when I submit 
them. Hopefully they can be fixed soon so I can try register and get the
 kit.
