The Golfing Analytics app tracks both 'make percentage' and 'strokes gained' for all distance ranges so that you can easily compare your putting performance and see how you're doing. You might even enjoy the game more when you realize that your putting might be better than you think and that it's unrealistic to expect to make everything like on TV.
