TheStack Baseball Swing Speed Trainer with App

In order to get better at baseball, you need to work on your swing technique all the time. TheStack Baseball is a swing speed trainer that combines with your phone to track your speed, distance potential, and other data points. It comes with a bat speed sensor and 5 CNC milled stack weights. The included sensor lasts over a year.

The app has a guided workout timer for reps, sets, and rest intervals. The Stack Bat is available in two sizes (Youth and Pro). You can adjust the weight for your bat from 0 to 400g. The sensor captures bat speed and syncs the data to your phone. You are going to need an iOS 15 or later to get started.
