Selfit Golf - Swing & Tracer

One video from the practice range is all it takes.
Selfit Golf reads your posture, scores it, tells you what to fix first — and draws the ball flight right on your video.

■ Swing Coach — what's wrong, in numbers

Record a swing or load one from your gallery. The app detects your body and splits the swing into five phases: address, halfway back, top, impact, finish.

· 18 measurements and an overall score
tempo, head sway, spine angle retention, shoulder and hip turn, X-factor,
weight shift, hip opening at impact, early extension, swing path and more
· Every measurement shown next to its recommended range
· Fixes ranked by priority, each with the likely cause and drills to work on
· Skeleton overlay on the still frame of every phase
· A trimmed clip of just the swing is saved so you can compare over time
· Share sends the skeleton-overlaid clip together with an HTML report

■ Shot Tracer — see where the ball went

Load a shot you recorded. The app finds impact, you tap the ball eight times, and it draws the rest.

· The app locates impact; you confirm it or move it yourself
· Eight taps and you are done. Pinch to zoom for an accurate tap
· Not a flat parabola drawn on the screen — a real 3D ballistic solution
gravity, air drag, backspin and side spin, so the line thins as it recedes
and a fade or draw keeps curving the way it should
· The line continues past the edge of the frame all the way to where the ball lands
· Save the traced video to your gallery or share it straight away

■ Who it's for

· Golfers who can't take lessons but want to know what to fix
· Anyone checking their own form at the range
· Players who want to keep a video of a good shot
· Anyone comparing this month's swing to last month's

■ How to record

· Face-on — belt buckle toward the camera, whole body in frame
· Down the line — aim where the ball will fly, whole body in frame
· A tripod or a wall to lean the phone on makes a big difference
· Shot Tracer works best against plain backgrounds such as sky or grass

■ Good to know

· Pose detection and analysis run entirely on your device. Recordings and joint
coordinates stay in local storage and are never uploaded.
· The distance and speed figures Shot Tracer recovers are not a substitute for
launch monitor hardware. What this feature delivers is the visible trace,
not a measurement.
· A busy background, or a ball that leaves the frame within a few frames, can
defeat it. When that happens the app says so rather than drawing a wrong line.
· Saved videos carry a "셀핏골프-Selfit Golf" watermark.
· Available in Korean and English.
