Hey guys, I have a 2 lanes for practicing and I've always wanted something like a Fitbit bracelet that I could wear and it would track my arm swing. I want an app that would then overlay the arm swing for 10 shots. I have a cats system to track my ball motion and its then displayed on screen and overlays 10 shots. Something for arm swing would be awesome. Any help on pointing me in the right direction is greatly appreciated. Thanks.
