tennis string tension Iphone app, is it for you?

Are you ever left wondering what tension would be best based on your game and racket, this Iphone app might be the ticket.  I have not tested it and cannot give a recommendation, but I thought that I would mention it here.  It is available in the Itune store for .99 cents.  It was released July, 2010.  This might just be for you if you have a difficult time trying to figure out your tension.
