TheStack App

TheStack is your personal trainer for clubhead speed, built to help you gain distance off the tee and play your best golf.

All you need to do is follow the TheStack App's custom guidance and train hard!

TheStack App will first ask you to complete a Baseline session so it can assess your current swing speed using a variety of Stack weights.

The App will then use that data to create a customized program for you, guaranteeing maximum results in minimal time.

Make your wedge practice fun and effective with this exclusive feature for the Stack Radar.

Stack Wedging generates skill-specific sessions with automatic Stack Radar integration, giving you precise carry distances in real time for the most seamless practice experience.

Practice Tracker transforms Stack Radar into a complete golf practice tracking system.

Track every practice shot, monitor meaningful performance trends, and build a complete history of your development as a golfer.

Stop wasting time on the putting green. Stack Putting is a data-driven platform designed to optimize your practice and help you sink more putts with gamified sessions.

Three unique modes - Premier, On Course, and Creative - offer different ways to track your performance and analyze your game from the practice green to the golf course.

Your game is more than just numbers on a scorecard. Record your round with Stack Stats to unlock deeper insights into your performance.

Compare your strokes gained in each category across a range of handicaps, track your progress over time, and understand your game like never before.
