The four metrics that move the ball: face angle, tempo, stroke length, consistency. Every stroke. Every session.
How square the putter face returns at impact compared to address. The single biggest factor in where the ball starts — roughly 80% of initial direction.
The rhythm between backstroke and forward stroke, and how repeatable it is across a session.
How large your stroke is, measured in degrees of rotation — useful for matching length to distance.
How tightly your strokes cluster session to session — whether the work is sticking.
Focused feedback. Not metric overload. TrueRoll tracks the stroke data golfers can actually use: face, tempo, length, and consistency.
Demo Mode gives you the full app experience — every metric, every screen, the TrueRoll Index — without a sensor. See how it works and what the data looks like. Then decide.
Try the App DemoMore data is not always better feedback. TrueRoll focuses on the numbers golfers can act on immediately: face angle, tempo, stroke length, and consistency. The goal is not to turn practice into a lab report. The goal is to help you make your stroke more repeatable.
