The Stack System

The Award-Winning App for golf enthusiasts is now even better. Stack your most important golf skills together and enjoy both longer drives AND fewer putts. Please note that TheStack App requires a training club purchase (includes 1 year membership), or an in-app subscription purchase.

STACK PUTTING ($59/year) is like having a Tour putting coach in your pocket. Enjoy gamified putting practice with analytics and insights about your putting not available anywhere else. STACK SPEED TRAINING ($99/year) powers distance gains through customized, variable inertia speed training - the most efficient way for a golfer to increase their clubhead speed, and includes Stack Putting and the Learning Library.

**STACK PUTTING OVERVIEW**
"Stack Putting is the best way I have seen to practice your putting and get proper feedback for corrections. I'm all in." -Ben Crane, 5-time PGA Tour Winner
PREMIER MODE
Stop wasting time on the putting green and gamify your practice with focused 15-minute putting sessions you can do on any putting green. Data entry is a breeze with our Voice Entry and Pocket Modes. The App will guide you through 18 holes on the putting green and have you hit the putts that are going to matter the most to your score. Enjoy actionable insights about your putting statistics to identify your strengths and weaknesses through beautiful data visualization (shot chart, spider diagrams, bar charts). See how your putting stacks up against your peers by picking any handicap baseline for statistical comparison. Compare mode allows you to experiment with different putters or techniques and measure differences so you can make smarter decisions about your game. Enrich your insights and boost your data quality by first passing TheStack Putting Certification Quiz.
CREATIVE MODE
Creative mode allows you to create your own putting combine with an easy-to-use template, or enjoy popular predesigned practice combines. Creative mode is great for indoor putting greens or if you want to focus on a specific area of your putting. You can also share your own designs with your friends by text or e-mail.
ON COURSE MODE
This feature was requested by our Beta users that loved the detailed analytics from Premier but wanted that level of detail from their on-course play. Seamlessly enter detailed on-course putt data to drive incredible insights that have more granularity than PGA Tour Shotlink putting data. Aimpoint enthusiasts have loved recording their exact grade percentage.

**STACK SPEED TRAINING**
“I’ll be honest, TheStack has worked wonders.” -Matt Fitzpatrick (2022 US Open Champion) after using TheStack to gain 20+ yards
Over 40,000 golfers of all skill levels and handicaps have enjoyed customized variable inertia speed training, which is the most efficient way for a golfer to increase their clubhead speed. Paired with TheStack training club, speed training algorithms power customized dynamic programming borne from years of experimental research by leading sport scientist, Dr. Sasho MacKenzie.
To start speed training you will need TheStack hardware and a compatible Speed Radar.
