Every page, in one place

Measure velocity, spin rate, spin axis, and pitch movement using nothing but your iPhone and a tripod. TrackMan-grade results without the TrackMan price.

Every PitchLab feature: velocity, spin, IVB, horizontal break, Stuff+, location, ball tracking, progress trends, and shareable videos, all from an iPhone.

For pitching coaches and teams: every pitch on video with velocity, spin, movement, and ball tracking built in, for every pitcher you coach, in person or remotely.

For coaches, teams, and facilities: request a free trial of the PitchLab Team plan, whether you coach private lessons, travel and high school teams, college programs, or run a training facility.

Track velocity, movement, and location for rise balls, drops, curves, and changeups with just an iPhone on a tripod. Softball pitch tracking made simple.

Watch the PitchLab demo and set up in under 2 minutes: an iPhone 12 or newer on a tripod 2 feet behind the pitcher, facing home plate. No radar gun or sensors.

PitchLab for hitters is in the works. Join the waitlist to hear first when it’s ready, and tell us about your game so we build what matters to you.

Plain-language definitions of pitching metrics: velocity, spin rate, spin efficiency, spin axis, gyro, IVB, horizontal break, Stuff+, and location.

Answers to common questions about PitchLab: how accurate it is, how it compares to TrackMan and Rapsodo, setup, coaching tools, pricing, and Android.

Pitch velocity is how fast the ball travels, in mph. See average, good, and elite fastball speeds by age and level for pitchers.

Spin rate is how fast a pitch rotates, in rpm. See average, good, and elite spin rates by pitch type, and learn what changes them.

Active spin is the part of a pitch's spin that makes it move. Learn how it differs from spin rate and see good active spin numbers for each pitch type.

Spin efficiency is the percent of a pitch's spin that creates movement. See what's good for fastballs, curveballs, and sliders.

Spin axis shows which way a pitch spins, read like a clock face. Learn what 12:00, 1:00, and 7:30 mean and the typical tilt pitches.

Gyro degree shows how much of a pitch's spin is bullet spin. Learn how it ties to spin efficiency and what gyro numbers to aim for on each pitch type.

Induced vertical break (IVB) measures how much spin makes a pitch ride or sink. See what counts as good IVB for fastballs, sinkers, and curveballs.

Horizontal break measures how many inches spin moves a pitch sideways. Learn arm-side vs glove-side break and good numbers for sinkers, changeups, and sweepers.

Stuff+ grades a pitch on its physical traits, like velocity, spin, and movement, with 100 as league average. Learn how it works and what makes a good score.

Pitch location shows where each pitch crosses the plate. Learn how coaches measure command and what strike, zone, and first-pitch strike rates to aim for.
