Leave it to a club manufacturer known for its personal customization to figure out how an app can help your putting game. iPing (Free;) is a new app for the iPhone and iPod touch that identifies your stroke type, analyzes your impact angle, and measures your tempo, creating a "Putting Handicap" that gets lower as you become more consistent. Simply pick up a Ping cradle ($30) for your iPhone 4 or iPod touch 4G, snap it onto your putter, and get to work.
Sometimes the best inventions come from unintended discovery — like how a piece of scrap cardboard tossed across a room became the basis for the Hela Disc ($19). Using a new aerodynamic technology called FlexFoil that allows the disc to change shape during flight, the Hela Disc can travel over distances of up to 300 feet depending on the skill of the thrower, can stare down 15mph gusts, and offers micro edge molding on the grippy, weighted ends for added accuracy.
