I’ve been seeing signs for Tunity in bars (airport bars as I’m walking through — I’m not hanging out in bars these days #nerdlife), and an attendee told me about it last week. At first I assumed it was just for people who are hard of hearing, but as soon as I tried it, I knew you guys would love it.

Tunity is a free app (iOS and Android) that lets you stream the audio from certain TV channels through your mobile device. This gives you the freedom to watch a muted TV and hear the audio on your own.

A few things to know about Tunity:

• Connecting Tunity takes seconds… just put the TV in the scan area on your phone, and if the channel is supported, you’ll be listening in less than 30 seconds.
• Tunity works with live TV only… you’ll have to find another solution to stream your Netflix.
• Tunity needs your location services to help detect the channel you’re watching.
• The service covers many standard cable channels, such as ESPN, CNN, TNT and the like.
• You can fine tune the synchronization with forward and back arrows.
• Yes, you will need to be connected to the internet to use it, but Tunity says it uses a minimal amount of data.

I’ve found myself using it all over the place, from the waiting area at an airport gate to a hotel room when I didn’t want to bother other guests with my blaring TV. And when I told my husband about this tool, he immediately asked me to download it to his phone. In marriage terms, that’s a win!

Here’s their chart about the many uses:
