A focused putting sensor and app. Tracks the four metrics that move the ball: face angle, tempo, stroke length, and consistency.
Includes the TrueRoll sensor, putter mount, and your first year of TrueRoll Pro. Renews at $79/year after the first year. Cancel anytime.
Lightweight motion sensor that attaches to your putter shaft. Tracks the stroke from address through impact.
Custom-designed mount that fits standard putter shafts. Holds the sensor in a fixed position so readings stay consistent session to session.
Full access to face angle, tempo, stroke length, consistency, session history, and the TrueRoll Index. Renews at $79/year after year one.
A single card with a QR code and your activation code. Scan, pair, putt.
No batteries, charging cables, or extra accessories required. The sensor charges via the included USB-C cable and runs for ~6 hours of practice on a full charge.
How square the putter face returns at impact compared to address. Roughly 80% of a putt's initial direction comes from face angle.
Learn more →The ratio between backstroke and forward stroke. Most tour pros sit between 2:1 and 2.5:1. Repeatable tempo matters more than fast or slow.
Learn more →How far back the putter travels, in degrees of rotation. Useful for matching length to distance.
Learn more →How tightly your strokes cluster within a session. Separates "I made one good putt" from "I built a reliable stroke."
Learn more →Focused feedback. Not metric overload. TrueRoll tracks what golfers can actually act on: face, tempo, length, and consistency. The TrueRoll Index synthesizes all four into one score per session so you can see whether you're getting better over time.
Slide the included mount onto your putter shaft. Tighten by hand — no tools needed. Fits standard shaft diameters.
The sensor clicks into the mount in one orientation. You can't put it on wrong.
Open TrueRoll on your iPhone. Tap "Connect." The sensor appears in 5 seconds.
Hit your first putt. Your first metrics appear on screen before you've lined up the second one.
Setup takes about three minutes the first time. After that, every session starts in under thirty seconds.
Track the four metrics that show up under pressure. Build a stroke that holds together when the round counts.
Travel-friendly. Fits in a tournament bag. Gives a junior and parent a way to talk about putting that doesn't require a coach in the room.
Simple metrics players actually understand. The kind of feedback that turns into the next drill, not a homework assignment.
Indoor mats and outdoor greens both work. Session history shows you whether your indoor reps are translating.
Your first year of TrueRoll Pro is included with the kit. After year one, renewal is $79/year. You can cancel anytime — your historical session data stays on your device even if you don't renew.

Try the App DemoThe TrueRoll sensor, the putter mount, your first year of TrueRoll Pro, and a quick-start card with your activation code. Nothing else to buy.
The mount fits standard putter shafts (most putters from the last 20 years). If your putter has an unusually wide shaft or a non-standard grip transition, contact us before ordering — we'll confirm fit before you buy.
No. Your first year of TrueRoll Pro is included. After year one, renewal is $79/year. If you don't renew, your historical session data stays on your device, but you won't be able to track new sessions.
Yes. TrueRoll works on indoor putting mats and outdoor practice greens. The sensor measures the putter, not the surface.
TrueRoll uses a 6-axis IMU sampling at 200Hz, processed on-device. The sensor is calibrated for consistent, repeatable session-to-session readings across all four metrics. We focus on giving you useful feedback, not marketing buzzwords.
No. TrueRoll is built for serious practice across competitive players, junior golf families, coaches, and home-practice golfers. Junior golf is one strong use case; it's not the whole brand.
Different focus. Capto and Vertex track 12–40+ metrics designed for coaching. TrueRoll tracks four metrics that a player can actually train. Different price points too — TrueRoll is $149 vs. $400–$1,500+ for those systems. See the full comparison on our compare page.
