Actually, I think this one is probably a tad more useful, and it's boring as hell, so I don't know where the TSA gets off thinking their app is so great.

Now, if these bozo's could put out out an app that tells you which checkpoint has the jackoscope in use, location of elite lines (remember those), educational accomplishment and mental status of TSO's at your checkpoint (in order to allow one to have the greatest amusement possible), etc,etc.
