Great tool!

Ive used this app many times with my 11yo select player. If you set it up exactly how the directions tell you to, you will see how great and accurate the app works. Its also a great motivator. When my son doesnt want to work bullpen, I tell him ill set up the radar and we can see if he can beat his fastest throw. That usually gets him off the couch. Its also great because I can see his fastball progress (he can hit 60 regularly) but when working on his change up, its good to have a quantifiable tool to show him how much slower his change should be from his fastball. We aim for 45 mph and ensure mechanics are the same as the fastball. Without this app, it would be a lot of guessing about what it working and what isnt. Highly recommend the full app.
