The iPing putting consistency app for IOS devices

This app, (available on June 20th 2011 for the app store) measures and reports on the style and consistency of your putting swing and suggests ways of improving that stroke, should be useful in lowering those handicaps!

Now why didnt I think of that! Although, with an additional purchase of a cradle "required" in order to use this device, you will have to be pretty dedicated to use it.
