“This is a must have app”
Great tool to help get data to help improve the baseball swing. If you’re a ballplayer, this is a must have app. If you’re a parent this will help provide you with the data and video to help your son or daughter improve their swing. Can’t recommend this app more.
“As a coach, I recommend.”
I began to use this app for my son and for some players I regularly train in private lessons (8-10yrs)... This tool is great as s gives real time feedback and showcases the difference between a 'bad habit' swing vs a good swing - as a coach, I reccomend.
“This app has never let me down.”
At 1st I was a little skeptical as there are so many other products in this space that simply dont work. This app has never let me down/ I started with my son and 9 months later I am using it to measure preseason vs end of season swings for my AAA Minor Little League team.
Game changer
I got this to see how I was doing and what I could do to my swing to do better. I was able to see what I could do to maximize my swing. This app has helped me alot!
Great Support & Developer Response
I had just written a review and, while perusing other reviews, I wanted to add another. I really appreciate the developer's responses not only to my post but to many others. Not a canned replay and not the ubiquitous rec. to contact customer support. Very impressive, and keep up the good work!
Great Tool!
Trying out this app, I saw Coach Murph used in one of his videos. This is an excellent tool for coaches and players for a great visual for swin analysis. I like to utilize video to break down a swing, and this app takes it to the next level with the great features, including exit velocity, launch angle, and bat path tracing. Love this. I only needed things I already had around the house - A phone and a Tripoid. Love b4!
