After thoroughly researching this type of application, I believe GSC is the best of its kind. Competitors are Anova, GRGS, Golfmetrics and myRoundPro. These apps are meant to cater to golfers looking for a numbers-based approach to improvement. Specifically, to understand where you are losing strokes based on validated benchmarks. These apps are not meant to help you navigate a course during the round through GPS or other features.
GSC has an excellent layout and the app is fast. It is a polished product, unlike some of the competitors (Anova is especially glitchy and slow). The price point is intermediate and I think acceptable for the service provided. It keeps track of all the stats you’d want and more, and breaks them down by different areas of the game, as well as by club used. It keeps track of driving distance and accuracy by club, which is great when reflecting on which club to use off the tee.
The only minor flaw, which they could easily fix, is that you have to input the Par and distance from the tee for each hole. Other apps will remember this for each course/ set of tees. I’d estimate this adds a minute or two when logging your stats after a round. Not a deal breaker by any means but easily fixable.
In summary, this is a great app for tracking in depth golf stats, and the best product of its kind.
