Fix your biggest weakness.
Every rep. Anywhere.
Start with our free diagnostic — it finds the #1 thing holding you back vs. the pro you're chasing. The sensors go exactly where that weakness lives. Two sensors. Real-time feedback. On the range, on the course, in the gym, in your backyard. No camera. No tripod.
Why Practice Stops Working
Reps without real feedback are reps you can't trust.
You can't feel what's actually moving
Your body's sense of its own position lies to you — especially on the moves you're trying to fix. You think you're doing it right. You're not. And nothing tells you in the moment.
Your coach isn't there at 6am
The reps that matter — the thousands between lessons — happen alone. Without feedback, your body defaults to the old pattern. You're not training the new move. You're reinforcing the old one.
Video review is slow and vague
By the time you watch the footage, your nervous system has moved on. Late feedback is better than nothing — but fifty years of motor-learning research says the closer feedback happens to the rep, the faster you actually improve.
How It Works
Three steps. Then you just move.
The diagnostic finds your biggest weakness. The sensors go exactly there. Every rep gets scored.
Diagnostic finds your weakness
Pick the pro you want to move like. Our free full-body diagnostic compares your mechanics to theirs and surfaces the #1 thing holding you back — wrist, elbow, hip, knee, posture, whatever it is.
Free · 5 minutesSensors go where it matters
The app tells you exactly where to place the two sensors based on your diagnostic. Full-body motion-analysis insight — with just two sensors, ready to go in seconds.
Attachment kit includedReal-time feedback on every rep
Score, speed, acceleration, peak angles — on your rep, compared to the pro. Auto rep detection. Session summary with rep-by-rep replay against the expert's good zone.
Live · no cameraWhat the Sensors Do
Every rep. Measured. Scored. Compared to the best.
Full-Body Insight. Two Sensors.
Because the diagnostic tells the app exactly where your weakness lives, two sensors in the right place gives you what used to require a full motion-capture lab. Ready in seconds, not hours.
Real Movement Metrics
Acceleration, speed, joint-angle peaks, rep duration — measured on your rep, compared to the pro you're learning from. Not estimates. Actual data from your body vs. theirs.
Full Attachment Kit Included
Wrist straps, arm bands, leg bands, hip belt, posture vest — think GoPro-style mounts, but lower-profile and purpose-built for movement. Wherever the sensors need to go, you're covered.
Expert Archetypes
Your target is a real coach or athlete's mechanics, captured from a single video. Not AI-averaged. Not generic. Your movement is measured against a specific human who does it right.
One Subscription. Every Sport.
Sign up for tennis — then drop in on golf, baseball, or anything else in the library. Same subscription. Full access. Train the way you actually use your body — across sports, not locked into one.
Auto Rep Detection
The app reads your noise floor in two seconds, then finds every rep on its own. Adaptive thresholds — it doesn't get confused by warmups or dead time between reps.
Per-Rep Scoring + Session Summary
Every rep gets a score. End of session: trend line from your first rep to your last, bar chart of every rep, and a replay of any rep's angle trace against the expert's good zone.
The Download — Pre-Session Priming
Before you move, the app primes your nervous system with the expert's movement blueprint. A 3-stage brain-priming flow built on PhD-validated neuroscience (this is where the 3.5% study comes in — more on that below).
The Part That Changes Everything
Immediate feedback. In the moment. Without setting up a camera.
Fifty years of motor-learning research points to the same conclusion: the closer feedback happens to the rep, the faster you improve. Not after a video review. Not at your next lesson. Right now, on the rep you just took.
On the golf course
Hit the shot. Check your wrist angle on the takeaway — right there on the 7th hole. Know before the next tee whether you're back in the pattern your pro flagged last lesson. Export your rep data and send it to your pro before you even get to the parking lot. They show up to your next lesson prepared.
Anywhere else you practice
Driveway at 6am. Hotel gym on the road. Batting cage alone. Two sensors, earbuds in, every rep scored. No tripod. No camera angle to get right. No performance anxiety because someone's watching you film yourself. You practice like a normal person — and you get lab-quality feedback doing it.
Also Included
GOAT Accelerated Learning Access
Your subscription includes access to our brain-priming learning system — built on the same research as The Download. Use it if you want to add another layer of skill acceleration. Skip it if you just want clean rep data from the sensors. Either way, it's there.
The Science
The only thing we're loud about: it's tested.
We're not going to hand-wave a "20x" claim at you. Here's what the research actually says.
The consensus isn't subtle: immediate, quantitative feedback on joint angles and velocity accelerates motor learning faster than almost any other training variable. Inertial sensors (IMUs) produce exactly that kind of feedback — the kind that used to require a lab. That's what the sensors deliver. Every rep.
This number comes from the priming protocol (the brain-side of GOAT — what powers The Download and our accelerated learning). It's not the sensor feedback number. We don't have a clean published number on the combined system yet. What we have is research consensus that real-time feedback dominates training variables — and customers who try it and stay.

Our Guarantees
Three layers of protection. Zero risk on your end.
We built the best system we know how to build. We'll prove it.
Layer 1 — The 1-Year "Measurable Improvement" Guarantee
Commit to the proven plan for one full year:
- Two 15-minute sensor sessions per week
- Five 5-minute accelerated learning sessions per week
If your GOAT Evaluation hasn't improved after a year of that, we refund 100% of your $399 and personally cover your first lesson with a GOAT-approved coach.
Layer 2 — 30-Day "Informed Decision" Guarantee (Unconditional)
Receive the sensors and use the full system for 30 days. If you don't think it's right for you — for any reason — send them back for a full no-questions refund of your $399. Your monthly subscription doesn't start until your sensors arrive and you activate the app, so you have time to experience the platform before the recurring charge begins.
Layer 3 — 1-Year Manufacturer's Warranty
Manufacturing defect within a year? We replace the sensors. Free. No paperwork, no hassle.
FAQ
Common questions.
What sports does this work for — and do I have to pick one?
Any sport where technique matters. Current library leans into golf and baseball with more added every month. And no — you don't have to pick. Sign up for tennis and you still get full access to golf, baseball, and everything else in the library. One subscription, every sport. Train the way you actually use your body.
What if I want an archetype that doesn't exist yet?
Use the Custom Archetype Request bonus included with founding orders. Tell us the coach or athlete. We build it inside 72 hours. Free during the founding period. Teams can contact us for bulk requests.
I have an iPhone. Can I still order?
Yes. The Android app is live now. iOS releases May 2026. Order today to lock founding pricing — you can activate the day iOS drops. Or if you want to start immediately, we can point you to a compatible Android device for under $99.
How hard is the setup?
If you can connect Bluetooth to earbuds, you can set this up. Our fast-start onboarding walks you through everything step-by-step. Most people go from opening the box to their first scored rep in under 10 minutes.
Can I cancel the monthly subscription?
Yes, anytime through the Google Play Store. If you cancel, you keep the sensors — you just lose access to the platform features and real-time feedback. The hardware is yours regardless.
Not sure if it fits your sport?
Email us: goat@goatloop.com. We'll tell you straight. If it's a perfect fit, great. If it's not there yet, we'll tell you that too. Either way your purchase is covered by the 30-day guarantee.
