Make your next session count

Give yourself a clear view

Film one swing with a steady camera, your whole body in frame and plenty of light. Face-on or down-the-line both work.

Find the same moment

Compare similar camera angles. Choose Sync off, pause each video at impact, then choose Sync Videos to see the swings move together. Choose Sync off to play, pause, scrub and slow down each video separately.

Look for one change

Draw a reference line, measure an angle, or save both annotated frames side by side. Use slow motion and frame stepping. Set the frame rate to match your file for accurate time steps.

LOCAL BY DESIGN

Your swing stays yours.

Videos are opened directly from your device. They are never uploaded or stored by this app. There is no account or analysis backend.

Google Analytics is optional and loads only if you allow it. You can turn it off at any time in . Your choice is saved in this browser.

Our hosting provider, Cloudflare, separately adds a web analytics beacon for page visits and performance measurements. The Google Analytics preference does not control this cookie-free hosting service. Your video content and swing measurements are not sent to it. About Cloudflare analytics.

Optional pose analysis downloads MediaPipe code and model files from jsDelivr and Google. Those services receive normal download requests, but not your videos. An internet connection is needed for the first model load.

Measurements are approximate, camera-dependent 2D observations for practice, not professional coaching or a prediction of ball flight. Frame steps use the rate you select; variable-frame-rate files may not land on every encoded frame.

Reloading the page clears your session. Save a PDF report to keep your frames, moments and results.

What would you like to do?

Start with a video. Drawing and comparison work without running analysis.

After analyzing, open Analysis beside a keyframe’s Set button for plain-language suggestions: what looks good, what to check and a practice step. Measurements follow the advice. The PDF includes the same suggestions.
