Does what it claims; and that's the best that can be said. I don't have the time it would take to describe all the ways this app is disappointing. In order to adjust an antennae using this app you would have to have a pencil and paper to write down all of the station number translations during the 15+ minutes it takes to manually """"""""""""""""scan"""""""""""""""" each individual station. Then manually type in the stations you want to tune/adjust in a tedious process of turn  type  wait  repeat. The alternative is to """"""""""""""""scan"""""""""""""""" them several times to make sure getting one station clear doesn't undo the tuning of another. This  of course  would take several hours if you live anywhere near a metropolitan area. There are 2 or 3 extremely simple UI enhancements that could make this """"""""""""""""simple"""""""""""""""" app actually usable. Since this hasn't happened in the last year  I don't expect it anytime soon. For the love of all that's usable  couldn't you at least retain the list of tuned stations to scroll through?! From my experience with app development  I can only imagine that the original app was written in less than an hour and the only development time devoted to it since has been debugging.""
