Swing Insights

Computed from your body tracking — observations to consider, not gospel.

Coach’s Notes

What we’re seeing

Pattern observations drawn from your body tracking and any launch monitor data you provided. Listed by significance — the most notable patterns first. Hedged language is intentional: golf swings have many causes for any given outcome, and we infer rather than measure.

33 Body Points

Advanced AI tracks shoulders, hips, elbows, knees and more across every frame of your swing.

100% Private

Your video never leaves your device. All AI processing runs locally in your browser. Nothing uploaded.

Works Everywhere

iPhone, Android, laptop. No app to install, no account, no subscription. Free, forever.

Pro Tips

Get the Best Swing Analysis

A few quick guidelines for the cleanest AI tracking from your phone. Five minutes of setup is the difference between a noisy result and a useful one.

Phone Settings

Record at 1080p, 120fps in regular Record Video mode — not slo-mo. Browsers can’t read iOS slo-mo files at native frame rate. On iPhone: Settings → Camera → Record Video → 1080p HD at 120 fps. Higher fps unlocks accurate swing speed measurement.

Hands at Center

Frame the shot so your hands sit at the vertical center of the screen. Fill 60-70% of the frame height. Leave some headroom above so the top of your backswing isn’t cut off.

Lighting & Background

Bright, even light works best — outdoor open shade is ideal. Plain backgrounds (sky, fairway, indoor wall) help the AI lock onto your body. Avoid backlight and busy backgrounds.

Camera Angle

Face-on (chest height, in front of you) shows tempo, head movement, and balance. Down-the-line (behind you on the target line, hand height) shows swing plane and posture.

Steady Camera

Use a tripod, phone stand, or solid surface. Don’t hand-hold and don’t zoom during the swing. Camera shake adds noise to every measurement the AI tries to make.

Keep Clips Short

5-30 seconds is the sweet spot. Trim before uploading — start a half-second before address, end a half-second after finish. Shorter clips analyze faster and give cleaner peak detection at impact.

How the AI Swing Analyzer Works

Three steps. No app to install. No account to create. Your video stays on your phone.

1

Record Your Swing

Use your phone in face-on or down-the-line view, ideally at 120fps for the best tracking. Make sure your full body is in the frame. 5-30 seconds is plenty.

2

Upload to the Tool

Tap “Choose Video” and pick your clip. The AI runs a quality check first — framing, lighting, frame rate, camera angle — then analyzes 33 body landmarks across every frame. Nothing uploads to a server.

3

Study Your Insights

Get tempo ratio, head movement, hip rotation, knee flex, and swing speed estimates with Tour benchmarks. Save the analysis to your phone or computer to share. Got launch monitor data? Toggle it on for ball flight metrics alongside your body tracking.

What Body Tracking Actually Reveals

Most golfers have never seen their own swing in slow motion with their body positions clearly mapped. The AI overlay shows you things that are nearly impossible to see at full speed:

Tempo ratio — backswing-to-downswing timing benchmarked against Tour data. Head movement — lateral and vertical drift through the swing. Hip rotation at impact compared to Tour standards. Knee flex retention — an early-extension red flag. Swing speed estimates with launch-monitor calibration in progress. Spine angle changes from address through impact.

This is the same body-tracking foundation found inside premium golf swing apps — the difference is that here, every metric tells you what it’s seeing, what the Tour benchmark is, and what to consider working on. And when conditions aren’t right (low frame rate, wrong angle), we don’t make up numbers — we lock the metric and tell you exactly how to unlock it.

Frequently Asked Questions

Everything golfers want to know about the free swing analyzer

Is this golf swing analyzer really free?

Yes — completely free, with no signup, email collection, watermarked exports behind a paywall, or trial period. The tool runs entirely in your browser using advanced AI body-tracking technology. There’s no premium tier and nothing locked behind a subscription. We’re currently in public beta and improving it every week.

Does it work on iPhone and Android?

Yes. The tool works on any modern smartphone or computer browser — iPhone Safari, Android Chrome, desktop Chrome, Edge, Firefox, and Safari on Mac. No app to download. Just open the page and upload.

What happens to my swing video? Is it private?

Your video never leaves your device. All AI processing happens locally inside your browser using your phone or computer’s own processing power. We don’t see it, store it, or upload it anywhere. When you close the tab, the video is gone.

What does the AI actually track and measure?

33 body landmarks across every frame — shoulders, elbows, wrists, hands, hips, knees, ankles, feet, head, and face. Connecting lines visualize your full kinetic chain.

From that tracking, we compute swing metrics with Tour benchmarks: tempo ratio (backswing : downswing), head movement (lateral and vertical), hip rotation at impact, knee flex retention, backswing length, and swing speed estimates. Each metric tells you the value, the Tour standard, and what your number suggests.

When conditions aren’t right for a measurement (e.g. low frame rate for speed), we lock the metric instead of guessing — and tell you exactly how to unlock it.

Will it track the golf club too?

Body tracking is our current priority and we’re sharpening it every release — pose stabilization, foot anchoring, swing speed calibration against real launch monitor data.

Club tracking is on our roadmap. Reliable shaft and clubface tracking at consumer phone frame rates (where the clubhead moves over 100 mph and motion blur is heavy) is a hard, mostly unsolved problem — that’s where multi-camera and launch monitor systems earn their cost. But we’re actively exploring approaches and will share progress as it happens. Stay tuned.

What’s the best video angle for analysis?

Two angles work best:

Face-on: Camera placed directly in front of you, perpendicular to your target line, at chest height. Best for seeing tempo, weight shift, head movement, and arm positions. Required for swing speed measurement.

Down-the-line: Camera placed behind you on your target line, at hand height, lens centered on your hands at address. Best for seeing swing plane, posture, and shaft angle.

Make sure your full body is in the frame, including the top of your backswing and your feet. Good lighting helps a lot.

Is there a video length limit?

Yes — 30 seconds maximum. Most users land at 5-15 seconds, which analyzes faster and gives the cleanest peak detection. If your clip is longer, trim it in your phone’s Photos app first (iPhone Photos and Google Photos both have built-in trimmers).

Can I save or share the analyzed video?

Yes — after analysis completes, you’ll see a Save to my Phone button on mobile (or Download to my Computer on desktop) that records a ~20 second clip with all the AI overlays baked in: skeleton lines, swing metrics HUD, and Golf Swing Lens branding.

On mobile, the share sheet opens with options to save to your camera roll or send straight to Instagram, TikTok, etc. On desktop, it downloads to your computer. Tag @golfsimulatorvideos if you post it!

Can I add my launch monitor data?

Yes. Toggle Launch Monitor Mode below the club picker before uploading. After the quality check, you’ll be prompted for ball speed, launch angle, spin rate, carry distance, and smash factor — all optional, fill in whatever your launch monitor gave you.

Works with any launch monitor: Garmin R10, R50, Mevo, Mevo+, SkyTrak, Foresight GCQuad, GC3, Trackman, Rapsodo MLM2Pro, Square Golf, Uneekor, ProTee, or any other. The outcome metrics show alongside your body tracking so you can see cause and effect.

How is this different from paid swing apps?

Most paid analyzers show confident-looking numbers regardless of whether your video was good enough to measure them. We don’t. When the frame rate or camera angle isn’t right for a measurement, we lock the metric and tell you exactly how to fix it — instead of feeding you a fabricated number.

We’re also actively calibrating swing speed against real launch monitor data (Foresight GCQuad ground-truth) to publish verified accuracy claims, and we let you pair the analyzer with your own launch monitor for outcome data alongside body metrics. That combination — honest body tracking + your launch monitor data + transparent calibration — isn’t something the paid apps offer.

Do I need a launch monitor or simulator to benefit?

No. This is just a video analysis tool — record any swing, anywhere. You’ll get tempo, head movement, hip rotation, swing speed estimates, and the rest of the body metrics from a phone video alone.

That said, if you have a launch monitor, toggling Launch Monitor Mode on adds the outcome side of the picture — ball speed, launch angle, spin rate, smash factor — for full cause-and-effect coaching. We’ve personally tested most launch monitors on the Golf Simulator Videos YouTube channel and offer free planning help if you’re shopping for one.
