## What is PitchLab?

Set a grip on the seams, then watch exactly what that ball does on its way to the plate.

PitchLab is a 3D pitch grip and physics simulator for pitchers, coaches, parents and baseball nerds. Build a grip, see estimated spin and break update live, then throw it down a regulation field and compare it against another pitch.

NINE TEXTBOOK GRIPS ON A 3D BASEBALL
Start with the classics: four-seam, two-seam, curveball, slider, changeup, splitter, cutter, sinker and knuckleball. Each grip sits on the actual seams of a 3D ball, so you can see where the fingers go and why it matters.

LIVE SPIN, VELOCITY AND BREAK ESTIMATES
Adjust the grip, seam orientation or finger spacing and the numbers respond right away. You'll see estimated velocity, spin rate in RPM, spin efficiency and break direction, a quick way to understand how small changes shape a pitch.

THROW IT WITH REAL PHYSICS
Pick right or left hand, arm slot, throwing power, max velocity and mound distance, from 40 ft Little League up to 60 ft 6 in. The pitch flies in 3D with drag and spin-driven Magnus movement. Use slow motion and an adjustable camera to follow the break, and watch knuckleballs flutter unpredictably.

SEE HOW MUCH IT REALLY MOVED
Results show break in inches and plate location on a strike zone, alongside a spinless reference ball. That comparison shows exactly how much movement came from spin.

PITCH A VS PITCH B
Throw two pitches on the same clock and see them side by side. Change one thing at a time and isolate which adjustment made the difference. It's a great teaching tool for coaches and a fun rabbit hole for anyone who loves the game.

BUILD YOUR LIBRARY
Save and name your pitches, adjust the strike zone and fine-tune physics settings to suit your experiments.

CUSTOM PITCHES (OPTIONAL)
Want to invent your own grip? The Custom Pitches unlock lets you drag any finger anywhere reachable on the ball and name your creation. It's a one-time $4.99 in-app purchase. No subscriptions, ever.

AN HONEST NOTE ON THE NUMBERS
PitchLab uses a simplified physics model. Spin, velocity and break values are estimates for learning and exploration. They are not measurements of your real throw, and the app does not track or measure your actual pitches.

PAID, CLEAN AND PRIVATE
PitchLab is a paid app with no ads and no account required. Everything works offline, at the field, on the bus or in the dugout.

Grab PitchLab, grip it up and see what your next pitch can do.
