We started, in the beginning, when I downloaded a 'free' gps golf tracker app for the hell of it.
I upgraded to the scorecard and statistics, not long after, and I was very happy for what I got for my money. Great stats and easy scorecard.
But this whole club tracker and newer SBS has blown my mind. The ability to overlay each rounds' shots has given me insight that I would never think of whilst playing. (i.e. always trying to shortcut a particular dogleg, EVERYTIME, :) )
I love this app that much, that I've gone out and purchased an "iphone' portable charger; to keep my battery tip top when on the course.
Keep it up fellas, keep it up.
