GOATY vs Blast Motion: AI Body Coach vs. Club Sensor
Blast Motion measures how the club moves. GOATY coaches how the body should move to make the club move correctly. The club is always downstream of the body.

What Blast Motion does well
Blast Motion sensors are compact and easy to use — attach the sensor to the grip end of a club, sync it with the app, and your post-swing data appears automatically. For tempo training specifically, having an objective number for your backswing-to-downswing ratio is more reliable than trying to count internally or rely on feel. Many teaching professionals use tempo data as a communication tool with students because it is concrete and trackable.
The on-plane percentage and face rotation metrics give some insight into club behavior beyond just speed. For golfers working on specific club delivery patterns with a coach, having that sensor data can add objective context to what the coach is observing visually.
Blast Motion's putting data is where the sensor has its strongest track record — originally designed for baseball and then adapted to golf, it has a longer validation history in the short game and produces actionable tempo data for putting stroke training.
The fundamental limitation: Blast Motion measures the club, not the body. Your tempo number, your rotation speed, your on-plane percentage — all of these are outputs of your body mechanics. They tell you what the club did after your body produced the movement. They do not tell you which part of your body created that result, and they do not coach you on how to change the body pattern that produced it.
The upstream problem: body drives club
Golf instruction has a fundamental causality: the body drives the club. Your pelvis position, your trail hip coil, your shoulder turn, your lead arm structure — these body mechanics determine what the club does. Club sensors sit at the end of that causal chain, measuring the final output.
If your tempo ratio is 3:1 (three times as long on the backswing as the downswing), Blast Motion tells you that number. But what is causing an inconsistent ratio? It might be a trail hip that fires at the wrong moment, an early shoulder turn at the top, a lead knee that collapses rather than stabilizing. Blast Motion has no way to identify which body pattern is the cause — it only sees the club result.
GOATY inverts this by watching the body directly. It tracks 17 keypoints at 30fps — pelvis, hips, shoulders, arms, wrists — and identifies which body positions and movement sequences are producing your swing outcomes. When GOATY delivers a coaching cue, it is targeting the body pattern upstream that is causing the club behavior you want to change.
No hardware, no setup friction
Beyond the body-vs-club measurement difference, GOATY also eliminates the hardware friction of club sensors. Blast Motion requires purchasing the sensor hardware ($100–$150), remembering to charge it, attaching it before practice, and managing connectivity with your phone. If the sensor loses charge or disconnects, you lose your data.
GOATY works from any smartphone with a camera. Prop your phone on a bag, against a chair, or on a tripod — anything that gives a face-on view at hip height. Open the live lesson, swing, and GOATY is coaching you. There is nothing to charge, nothing to attach, no hardware to lose or forget. The barrier from "thinking about practice" to "being coached" is as low as possible.

What does Blast Motion measure in golf?
Blast Motion sensors attach to the grip end of clubs and measure swing tempo ratio, club rotation speed, face rotation, on-plane percentage, and impact efficiency — all via a grip-end sensor. Data is delivered post-swing through the app. Blast Motion measures club movement, not body mechanics.
Is Blast Motion worth it for golf?
Blast Motion provides useful tempo and club rotation data — knowing your backswing-to-downswing ratio is helpful for timing and consistency. However, it only measures club movement, not the body mechanics that drive it. For golfers who want coaching on why their tempo breaks down under pressure, body mechanics feedback from GOATY is more actionable than club sensor data alone.
Does Blast Motion coach your swing?
Blast Motion delivers post-swing tempo and club data — not real-time body coaching between reps. After each swing, you see numbers in the app. There is no voice coaching, no live body tracking, and no feedback on the body mechanics that drive club movement. GOATY watches your body at 30fps, scores each rep live, and speaks a targeted coaching cue within seconds of every swing.
What is a Blast Motion alternative that coaches body mechanics?
GOATY coaches 17 body keypoints in real time with voice cues between every rep — no sensor hardware required. While Blast Motion measures how the club moves, GOATY coaches how your body should move to make the club move correctly. GOATY works from any smartphone, costs $25/mo, and requires no hardware purchase or setup.
Free. No signup. Prop your phone face-on, take a swing — GOATY coaches your body mechanics immediately.
