Well it kinda works, sometimes if your phone is always unlocked... – Tunity: Hear Any Muted TV Live Review

It uses location services intrusively there is no way it actually uses location services to detect if you’re in front of a TV (how does that even make sense, do they have GPS coordinates of every TV? Lol) also if your phone locks at all the audio stream ceases even with location services always enabled. The ads are ridiculous and why does this need a twitter feed that you can’t even tailor to your preferences lol. This app is probably just mining and selling your location and personal data.
