Putter On The Go for iPhone

27 Sep

Putter on the Go is the putting distance simulator for iPhone 4.  It lets you practice your putting stroke anywhere, anytime and gives you feedback on how far the putt would have rolled under a variety of green conditions.  Building a better feel for putting distance will allow a confident putting stroke, help reduce three putts and eliminate the three most dreaded words in golf, “You’re still away.”


Afraid of the slippery greens at the local country club?  Putter on the Go can accurately simulate greens up to a lightning 16 on the stimpmeter so you can practice in advance.

Not sure how much to dial back a downhill putt or how much harder to strike an uphill putt?  Putter on the Go can simulate hills from 10% downhill to 10% uphill to cover the most drastic green contours so you can internalize the effects.

How accurate is the application?

27 Sep

In thinking about this question, it is important to note that putting is a highly variable exercise – putts rolled with near identical speed and near identical direction will end up inches apart even over relatively short distances.  When this is compounded with imperfect strikes on the putter face and imparted side spin, two putts that feel similar can end up feet apart.  Said another way, sometimes the result you see with your eyes can fool you.

When calibrated against a custom built pendulum to repeat swings as perfectly as possible, the Putter on the Go produces results that are consistently within 5% of the pendulum’s measured speed.  The accelerometer and digital gyroscope contained within the iPhone 4 are quite capable of resolving motion at these speeds.

How does that translate to on course results?  Let’s look at that a couple of ways:

In recent testing, a user hit twenty five putts on a green measured to 7.01 stimp. The putts were measured by tape measure and compared with the results reported by Putter on the Go.  While there is significant and expected variation between the compared results of any individual putt, the averages of the twenty five putts were within six inches of each other over eight to twelve foot distances, the deviations were very similar and there was high mathematical correlation (R>0.7) between the two datasets.

What does that mean?  Let’s try it this way.  I personally played a tournament round last weekend on greens substantially faster than my home course green which run between 7 and 8 on the stimpmeter.  In preparation for the round, I practiced ten, twenty and forty foot putts on a 10 stimp green using Putter on the Go.   Under the pressure of the tournament, having to putt everything out and the course conditions, I three putted only once when I pulled a three foot putt.  My distance control on long putts was excellent.
