Golf Swing Analysis App: Frame-by-Frame AI Breakdown of Your Swing
Most golfers have no idea what their swing actually looks like. They feel one thing but the video shows something completely different. A golf swing analysis app bridges that gap by breaking down your swing objectively, frame by frame, and telling you exactly what is happening at each phase.
GolfCoach goes beyond simple video replay. It uses AI pose detection to find your joint positions, overlays a skeleton on your video, and scores four critical mechanics. The entire analysis takes under 3 seconds.
Record a 5-second swing video. Get a complete analysis with skeleton overlay, metric scores, coaching tip, and drill recommendation in under 3 seconds.
What the Analysis Shows You
When GolfCoach analyzes your swing, you get a multi-layered breakdown that goes far beyond "nice swing" or "you sliced it":
Skeleton Overlay
The AI detects your joints — shoulders, hips, knees, elbows, wrists — and overlays a skeleton on each key frame of your swing. This lets you see exactly where your body is at address, the top, impact, and finish. Positions that would be invisible to the naked eye become immediately obvious.
5-Phase Breakdown
Your swing is broken into five key phases, each analyzed separately:
1
Address
Setup position, posture, alignment. The foundation for everything that follows.
2
Backswing / Top
Club path on the way back, shoulder turn, hip restriction, wrist position at the top.
3
Transition
The critical moment between backswing and downswing. Where most faults originate.
4
Impact
Club face angle, shaft lean, hip clearance, head position at the moment of truth.
5
Follow-Through / Finish
Extension, balance, rotation completion. Reveals deceleration or casting patterns.
4 Key Metrics Scored
Swing Plane — Inside / Neutral / Outside
Tracks your club path relative to the target line. An outside path is the primary cause of slices. An inside path can cause hooks or pushes. Neutral is the goal for most shots.
Hip Rotation — Good / Limited
Measures how much your hips rotate during the backswing and through impact. Limited rotation forces compensations with the arms and reduces power.
Head Stability — Stable / Excessive Movement
Tracks lateral and vertical head displacement throughout the swing. Excessive movement shifts your swing center, making consistent contact difficult.
Tempo — Smooth / Rushed
Calculates your backswing-to-downswing time ratio. A smooth 3:1 ratio is the tour benchmark. A rushed tempo usually means snatching the club from the top.
How to Record the Best Swing Video for Analysis
- Angle: Down-the-line (camera behind you, aligned with target) for plane and path. Face-on (camera facing you) for rotation and weight shift.
- Distance: Place your phone 8-10 feet away at hand height.
- Duration: 5 seconds is enough. Include your setup and full finish.
- Slow motion: Supported but not required. Regular speed works well for the AI.
- Lighting: Outdoor daylight is best. Indoor works if the background provides contrast.

Frequently Asked Questions
How long does the analysis take?
Under 3 seconds from the moment you confirm your swing positions. The AI processes the video, runs pose detection, evaluates all 4 metrics, generates a coaching tip, and returns the results almost instantly.
What is the skeleton overlay?
The AI detects your joint positions (shoulders, hips, knees, elbows, wrists) in each key frame and draws lines connecting them. This creates a stick figure overlay on your swing video, making it easy to see your body positions and compare them across frames.
Can I compare two swings side by side?
Yes. GolfCoach includes a swing comparison feature that shows two analyses side by side, highlighting what improved and what regressed between them.
Do I need a tripod?
No. A golf bag, bench, or a friend holding the phone works fine. The phone just needs to be stable and at roughly hand height, 8-10 feet from the ball.
Is the analysis accurate for all skill levels?
Yes. GolfCoach adapts its feedback to your handicap range. A beginner receives different coaching language than an advanced player, even for the same fault. The 4 core metrics apply at every level.
