TheStack App

Training made easy with the award winning App. Guided programs, timers, effortless data-entry, and track key metrics on your speed journey.

Programs

Following the Baseline Session, TheStack App provides a list of customized programming options. The list is prioritized specifically for you by greatest likelihood of increasing clubhead speed over a 6 to 10 week period (18 to 24 training sessions).

Training

During each training Session, TheStack App coaches you through each swing - seamlessly guiding stack weight configuration, swing intent and rest for each rep and set.

Hands-Free Data Collection

Using TheStack System’s voice entry technology, enjoy hands-free data collection during training sessions, by simply dictating your speed readings into the App. The hands-free data capture feature even works when wearing AirPods or earbuds. If you are training with a coach or friend, numbers can be keyed.

Workout Summaries

Detailed post-workout data review enables you to verify and, if needed, make any changes to speed data before syncing to the cloud.

Tracking and Sharing Metrics

TheStack App tracks key performance metrics such as Stack Speed, Distance Potential, Clubhead Speed and Grit Score. Easily share your progress and gains to your favorite social media platform.

Progress Checks

After completing a training program, TheStack App re-assesses your gains with a Progress Check, from there reformulating your next program. Data captured along the way improves the intelligence of TheStack algorithms through A.I. techniques.
