Review on ⚾ Diamond Kinetics SwingTracker: Enhance Your Baseball & Softball Performance! by William Stevenson

Failed to download app. Try it on two different phones and also on two different models of IPADS / Tablets. The announcement should also mention that an annual or monthly subscription is REQUIRED to use the app. The ad is only for the tool and the trial version of the app (if you can download it!) From the description I was very excited as it was exactly what I was looking for. Received once. AS said very disappointed. The APP subscription fee is another deterrent. I would not recommend this product. Returned for a refund!
