FORTUNE -- Alex Fitzpatrick's piece in Mashable Wednesday about Super PAC App -- a free application for Apple's (AAPL) iPhone, iPad and iPod touch -- pitched it as a tool for finding out who paid for a particular political ad.

The app uses TuneSat, a technology developed to spot unauthorized use of copyright music, to identify an ad by its audio signal. Just hold your iOS device up to the speakers -- as you would with music apps like Shazam or SoundHound -- when a political ad appears and Super PAC will try to match the ad to its database.
When I tested the app on ads I found on YouTube, it only worked about half of the time. But when it worked, the claims testing function was both useful and relatively nonpartisan. I learned, for example:
You can download Super PAC App from the iTunes store here. Did I mention that it's free?
