I do it by hand. Too cheap to pay extra for data and a smartphone. I even track where in the pocket the ball hit, what I hit, what I actually aimed at, speed and anything I can think of. I fund I was making my adjustments sooner this way and it's helped me. Am I anal? I don't know but I can tell you what ball, speed, rotation, approximate rev rate, line played for the third frame of my second game six months ago and where it actually hit plus the score.
