What it tracks?
Consistency

Face angle
On GSA PUTT app, it shows both the putter’s face angle at impact and face angles along the stroke, relative to address. + means Open and - means Closed. Open is when the face is pointing out to the right and Closed is when the face is pointing out to the left.

It is the vertical (up-down) angle at which the putter head is moving at impact, relative to address. +ve means hitting up on the ball, while -ve means hitting down on the ball.
Tempo

Backswing time

Downswing time
It is the time taken of your forward swing to impact. It can be shown up to 2 decimals of a second. (follow through is not included)
