Mark Blackburn, Golf Digest #1 Coach
"Super excited about the opportunity to use this technology for on course kinematic sequence captures and movement training in gym or on the range! Sure to become a great tool for building body & pivot feels for players in PLAY & Practice!"

Golf Digest
"What’s different about Kim’s product is that it tells you exactly what you are doing differently on the range and on the course, allowing you to identify the factors that are keeping you from swinging your best when you need it most.”

Golficity In Depth Review
“So now we have zero excuses to become a better golfer on the course! … Are we a different golfer on the range vs the course. We showed that I am and now I know what to work on!.”
How it works
1) Analyze your swing
See your avatar next to a tour pro, side by side or overlaid.
Your top 3 flaws are immediately illustrated so that you know both what adjustments are needed and how.
Full 3D analysis is also there when you need it.
2) Train with live biofeedback
Real improvement doesn’t come from more reps. It comes from better reps.
- Visual – A 3D avatar mirrors your body live
- Hit the target zones and turn them green.
Just put on the shirt, turn it on, and follow the program.
This is how you develop proper feel.
3) Capture what changes on the course
You stripe it on the range… but fall apart during your round. Why?
Now you can finally see:
- Where your swing breaks down under pressure
- And how to fix it for good
Say goodbye to band-aid tips. Build a swing that actually holds up.

Still Not Sure? Let Us Remove Any Concerns
Too expensive?
This replaces guesswork with measured feedback and guided training. Most customers use it as their “practice system” between lessons and range sessions.
Is the data complicated?
The app prioritizes what matters and turns it into clear checkpoints and training targets.
Will I stop using it?
Training is built for short sessions. Biofeedback keeps reps in-range so practice stays high quality.
Why not just work with an instructor?
Instructors are great. This gives you feedback on the swings between lessons and helps you keep changes on track.
Is setup difficult?
Setup is quick. Pair once, put it on, and start.
Frequently Asked Questions
FAQ
Do I Need An Apple Watch For This To Work
No — Par and Birdie work without an Apple Watch. Apple Watch is required only for Ace features.
Sizing Chart And IOS Specs
See Sizing Guide and Specs above.
Will this help me if I'm a beginner?
Yes. The app shows what to work on and guides short training sessions with clear biofeedback—no guesswork.
Is it simple to use?
Yes. Put on the shirt, turn it on, open the app, and follow the program.
Does it work for both left-handed and right-handed golfers?
Yes. Enter your dexterity in your profile and the system automatically adapts to both left- and right-handed golfers.
How does this help me on the course?
The 3D Smart Shirt is made from a light moisture wicking material so it can be worn under your golf shirt. It captures your swing automatically and shows you exactly what you’re doing in real-time—right on your Apple Watch or iPhone. No cameras, no setup. You’ll know immediately what swing flaw caused a bad shot and how to fix it before your next swing. You can also review your round and see what swing flaws emerge on the course that do not show up on the range.
Will it help me to gain more distance?
Absolutely! Among other things, the 3D sensors can measure your Kinematic Sequence, Rotational Speeds, X-Factor and X-Factor Stretch. By properly accelerating and decelerating your pelvis, torso and lead arm, you can gain speed almost instantly. Just adding a few degrees of X-Factor Stretch creates a whip like effect that most amateurs are leaving in the bag. Our Learning Center has a growing list of videos that shows you exactly how to use the system to achieve your desired objectives.
Is the motion data recorded in real-time?
Yes. Your swing is captured and analyzed instantly—within seconds of impact. You get feedback while the feel is still fresh.
In Biofeedback training mode, you see a live avatar of yourself, moving as you move - it guides you into the proper positions throughout the swing. Learning the golf swing can be as simple as playing a video game.
Do I need an internet connection for it to work?
No. You can use it on the course without Wi-Fi or cellular. The shirt and app sync locally, and data uploads to the cloud when you’re back online.
Is it compatible with iOS and Android?
It is currently compatible with iOS (iPhone and Apple Watch). Android compatibility is coming soon.
