Need some help with your short game but are too cheap to hire a pro to give you lessons? A new accessory allows you to strap your iPhone on to your putter and have it give you feedback on your swing.
Simply pop in your iPhone, take some swings, and the iPing app will quantify your putting handicap number, allowing you to compare it to your golfing buddies and some built-in pros. I'm sure that'll help you improve your game. Either that or the added weight of an iPhone on your putter will completely throw you off. Only one way to find out!
