Review on ⚾ Diamond Kinetics SwingTracker: Enhance Your Baseball & Softball Performance! by Lagant Wardrick

I bought this hoping to improve my son's results. While it appears to follow the path of the bat, the app offers no guidance on what counts as a good swing or how to get better. Also, you can't view past beat episodes for analysis. If you spend an hour tracking swings and stop using the app for a period of time, you will be prevented from viewing your swing history. You can view "past" sessions only by paying a monthly fee. So unless you're willing to pay for a device AND pay a monthly fee, you're literally getting nothing of value.
