## Description

Tracking Lab is a pitch lab for enjoying pitch-tracking data. Design your stuff — velocity, spin rate, spin axis, gyro angle — and watch the physics simulation draw the trajectory instantly.

PITCH DESIGN — Create
Shape your pitch with mixer-style faders. Tracking metrics — spin efficiency, movement, Bauer Units — respond in real time. Save your creations as My Pitches.

BULLPEN — Refine
Hold the ball and release the moment the green ring wraps it. Early or late releases and finger slip carry into the flight; after landing you see why you missed and by how far. The 10-pitch exam grades your release repeatability A–E while the catcher's target moves every pitch.

STRUCK OUT — Test
Break the nine-panel target with the pitches you refined. Scoring with a pitch you designed yourself multiplies your points, and your best score goes to the Game Center global leaderboard.

Everything — measurement, simulation, records — runs on your device. No account, no ads.
