GolfFiT: AI Swing Analyzer

Review the swing you filmed at practice, with measurements you can check in the video. GolfFiT supports golfers practising on their own.

See estimated knee and arm angles alongside the relevant moment. Scores use GolfFiT's own posture reference angles; untrackable joints are excluded.

MEASURED POSTURE
The app finds a setup-to-finish interval, then estimates 3D joint positions to measure knee bend at setup and arm bend at the top. Tap a measurement timestamp to review that moment.

A SCORE WITH A BREAKDOWN
When both setup and top measurements are available, GolfFiT shows a posture reference score out of 100. Untrackable joints are excluded. Shot-shape inputs do not reduce your score.
The score uses GolfFiT's own reference angles, not a validated rating of golf ability. Suitable posture varies by player and club. Compare videos from the same camera position with the same measured items.

PRACTICE AND REVIEW
See observations based on the measured arm and knee positions, with a movement to revisit or compare in your next recording. Clubface direction, ball contact and weight distribution require additional measurements.

MORE PRACTICE TOOLS
Explore possible causes and practice ideas for common misses. Keep measurement history, estimate club carry distances, choose a club for the remaining distance and record round scores and putts.

No account is required. Videos are processed on your device and are not uploaded for analysis. Loading the analysis models requires an internet connection. Choose a clip of up to 60 seconds showing your body from setup to finish.
