Analyze My Swing Free →Complete Phone Setup Guide
Step 1 — Position Your Phone
- Distance: 8-10 feet directly in front of you
- Height: Hip level — roughly waist height
- Angle: Face-on — camera pointing at your chest, perpendicular to your target line
- Stability: Prop against a golf bag, use a small tripod or phone stand, or ask someone to hold it still
- Framing: Check that your full body is visible — head to feet — before you swing
Common mistake: Filming down-the-line (from behind) instead of face-on. GOATCode.ai's free analyzer is calibrated for face-on video. Down-the-line is a different reference frame and will reduce analysis accuracy significantly.
Step 2 — Camera Settings
- Mode: Standard video — not slow-motion, not burst, not portrait mode
- Frame rate: 30fps or 60fps both work well. 120fps slow-motion is NOT needed.
- Resolution: Default is fine. 1080p is ideal, 720p works. 4K is unnecessary and creates large files.
- Stabilization: Turn on if available — reduces camera shake
- Orientation: Landscape or portrait both work — choose what fills the frame best with your full body visible
Step 3 — Lighting
- Indoor: Face the room's light source, not a window behind you. Turn on overhead lights. Avoid strong shadows across your body.
- Outdoor: Position so the sun is in front of you or to the side — not directly behind you creating backlighting. Early morning or late afternoon gives the most even light.
- Avoid: Filming with a bright window, doorway, or sky directly behind you — backlighting silhouettes your body and reduces landmark tracking accuracy
Step 4 — Film the Swing
- Start recording before you take your address
- Complete one full swing — address through finish
- Stop recording shortly after — 3 seconds total is the ideal clip length
- Check the clip: full body visible throughout, no major lighting issues
- Trim if needed: just the swing itself, not a long segment with lots of standing still

After your video analysis, GOATCode.ai also offers a live lesson mode — your phone becomes a real-time coaching station while you practice. Instead of uploading a video, the AI watches through your camera as you swing, evaluates each rep, and speaks a coaching cue within seconds. That's the rep-by-rep coaching option for golfers who want guided practice rather than a one-time diagnostic.
Frequently Asked Questions
Can I analyze my golf swing with just my phone?
Yes. GOATCode.ai lets you film your swing with any phone camera, then upload the video at goatcode.ai/analyzer.html for a free AI analysis. The AI processing runs on GOATCode.ai's servers — your phone is just the camera. You receive a 0-100 GOATScore with ENGINE, ANCHOR, and WHIP breakdown plus fault diagnosis in under 60 seconds. No extra equipment, no app download.
How do I set up my phone to film my golf swing?
Place your phone at hip height, 8-10 feet directly in front of you (face-on — camera pointing at your chest). Your full body must be visible from head to feet. Prop it against your golf bag, use a small tripod, or ask someone to hold it. Standard video at 30fps or 60fps is ideal; slow-motion is not necessary.
Does my phone need to be a recent model to analyze my golf swing?
No. GOATCode.ai's analysis runs on its own servers, not on your phone's processor. Any phone that can film video and open a browser page can use the free analyzer. Older iPhones and Android phones from the past several years all work equally well for filming and uploading.
What phone features do I need to analyze my golf swing?
A camera, a browser (Safari, Chrome, Firefox), and an internet connection to upload the video. That's it. No special camera settings, no high frame rate required, no specific resolution needed. Standard phone video quality is sufficient for GOATCode.ai's biomechanical analysis.
