SwingGhost - Golf & Tennis 3D

Film a golf or tennis swing on your phone, see it in 3D, compare it side by side with tour pros, and get clear coaching on what to work on first.

Golf
• Step through address, backswing, top, impact and finish in 3D; turn it face-on, down the line or from above and play it slowly
• See your position and a tour pro's at the same moment, side by side or overlaid; the pro follows your rhythm
• One thing to look at first: the clearest point, in plain words, with a way to practice it
• It only flags what is clearly visible, like standing up or lifting your head, and never guesses what an angle can't see
• From a video up to 1 minute, pick up to 5 swings and analyze them at once

Tennis (beta)
• Upload a rally video up to 1 minute and we find the near-side player's swings and show them as snapshots
• Analyze forehands, one- and two-handed backhands, serves and volleys in 3D and compare each phase, from unit turn and load to contact and finish, with a tour pro
• See the order of your kinetic chain, from legs to hips, trunk and arm, with measured values
• Real 3D replay (beta): rebuild the whole rally in 3D from the same video and watch it from any angle

Share
• Send one link and the other person sees your 3D swing and coaching on the web, no app needed.

How to film
• Golf: face-on or down the line, tripod, about 3–4 m away, whole body in frame, 60fps recommended. A practice swing without a ball works too.
• Tennis: from behind or beside the court with the player's whole body in frame, 60fps or more recommended.

What we don't measure
Club or racket speed, face angle and path, spin, distance and ball speed aren't measured. Only your body movement is analyzed.

Free tool: compare two videos
Play any two clips in sync side by side or as a ghost, draw lines and angles and export — on your device, no account needed.

Privacy
For golf, only the swing clips you choose (2.5 s before and 1.5 s after impact) are sent. For tennis, the rally video you choose is sent to find your swings and deleted after 24 hours (if you make a real 3D replay, a copy is kept until it's finished). Uploads are used only for analysis and deleted within 30 days. Analysis requires signing in. Two-video comparisons never leave your device. You can turn off a share link at any time.

Free and SwingGhost Plus
Analyze a few swings for free every week. SwingGhost Plus lets you analyze more every month, make more real 3D replays and keep share links longer. Swings we can't analyze never count.
