Trace the ball.
Then find out why it went there.
Every tracer app draws a pretty line and stops. SwingFix draws the line, reads your body through the whole swing, and tells you the one thing that is actually costing you shots.

- No app store

How it works
Three steps, and none of them involve a launch monitor
The whole thing runs on your device. That is why it can be free — there is no GPU bill sitting between you and an answer.
Film one swing
Face-on or down the line, phone propped against your bag. Ten seconds is plenty. Upload it or record straight into the app.
The engine goes to work
Camera shake is compensated, your body is tracked frame by frame, the swing is split into phases, and the ball is followed from impact into flight.
You get one thing to fix
Not a list of twelve. The single fault costing you the most, what it is doing to your ball, and a drill matched to it.
See it in action
Real swing. Real diagnosis.
Unedited output from SwingFix Pro's own engine — a real upload, real pose tracking, no cherry-picked numbers. If your swing has a fault costing you distance, this is exactly the kind of thing it will call out.
Early Extension
Your pelvis moves toward the ball through impact instead of rotating in place — measured at 39%, when anything over 12% is a problem. Standing up adds loft and moves the low point behind the ball, which is why irons fly high and short.
The fix
Feel like your belt buckle stays back while it spins left. Your hips turn, they don't slide forward. The chair drill makes this impossible to miss.

Where this started
Built by a real golf community, not a lab.
SwingFix Pro grew out of Golf & Gains — a Saturday golf group in Vientiane that kept running into the same faults, round after round. No coach on call, no launch monitor at the range, just a phone propped on a bag and a question nobody could answer: what am I actually doing wrong?
The Swing Check and the engine behind it exist because that group needed an answer that didn't require a lesson to get. Every fault it names, it names because someone in this photo swung it first.

What you get
A tracer is the start, not the product
Shot Tracer is genuinely excellent at drawing a line. Nobody has been as good at telling you what your body did to put it there.
Broadcast ball tracer
Motion-compensated tracking with a physics-fitted flight path. Five styles, tapered comet stroke, apex marker, no watermark on Pro.
Full-body skeleton
Spine angle, shoulder and hip turn, X-Factor, weight shift, head movement. Measured, with a target range next to every number.
Tempo and phases
Address, top, transition, impact, finish — detected automatically. Your backswing-to-downswing ratio against the 3:1 benchmark.
Progress that means something
Score trend, tempo trend, and which faults keep coming back. Compare any two swings side by side, frame for frame.
Coaching grounded in your data
Written from your measurements, never from guesswork. If the camera could not see it, the report will not claim it.
Export and share
Render the tracer over your video up to 4K, or generate a score card built for a phone screen and post it.

Questions
The things people actually ask
Do I need to download anything?+
No. It runs in your phone or laptop browser. You can add it to your home screen and it behaves like an app, but there is no App Store step and no update to install.
How accurate are the distance and speed numbers?+
They are estimates from a single camera, and we label them that way everywhere. We scale from your height, which you can set in Settings, and only report speed from a face-on angle where the maths is defensible. A launch monitor will always be more accurate — we would rather show you an honest estimate than a confident wrong number.
What if the tracer misses the ball?+
It will tell you rather than draw a fake line. Indoor nets, low light, and shots that leave the frame in two frames are the usual causes. The body analysis still works in all of those cases.
Does my video get uploaded?+
The analysis itself runs entirely on your device — the video never has to leave it for the engine to work. Your clips are stored in your private library so you can compare swings later, and you can delete any of them permanently at any time.
Is this replacing my coach?+
No, and it will not pretend to. It is the thing between lessons that tells you whether the change your coach gave you is actually happening.
Your practice swing feels perfect.
