About this app

Film one pitch or one swing, and see what your body actually did.

Form Analyzer estimates a 33-point skeleton from your video, finds the key moments
of the motion on its own, and turns each of them into numbers you can act on.
Everything runs on your phone. Your clips are never uploaded.

■ Built for baseball and softball
Baseball pitching is analyzed as an overhand delivery. Softball pitching gets a
dedicated windmill analysis — release beside the hip, how close the arm brushes the
body, how fast the arm covers the bottom half of the circle. Batting is shared,
because the swing is mechanically the same in both sports.

■ Key moments, found automatically
Pitching: set, peak leg lift, foot plant, release, follow-through.
Softball: start, stride plant, top of the circle, release, follow-through.
Batting: stance, stride plant, top, impact, follow-through.
Tap any of them to jump straight to that frame.

■ What gets measured
Elbow height at foot plant, trunk lean at release, hip-shoulder separation
(the X-factor), stride length, front knee angle, head movement, arm and hand speed,
swing time from top to impact, and more. Each number is shown against a target range,
with a short note on what it means for your mechanics.

■ Slow motion with the skeleton on top
Play back at 1x, 0.5x, 0.25x or 0.1x, step one frame at a time, and toggle the
skeleton overlay on and off.

■ Compare two clips side by side
Line two videos up on release or impact and play them together, so differences in
timing show as clearly as differences in position. A table shows the gap in every
shared metric.

■ Private by design
Videos and results are stored only on your device. No account, no upload, no sharing.

■ Getting good results
Mount your phone so the whole body stays in frame. Film pitching from the side and
batting from the front or the open side. Values are estimated from 2D video, so
compare clips filmed from the same camera position — the app is built for measuring
your own progress, not for scoring you against anyone else.
