Spin Lab HQ vs Reactr

SpinLab HQ transforms raw Trackman data into a complete player development system for pitchers and hitters. On the pitching side, every pitch is graded using two calibrated systems: Stuff+ measures pitch quality against professional baselines while D1 Grade evaluates against Division 1 college standards, giving coaches and athletes clear benchmarks for where they stand and where they need to go. The app breaks down each pitcher's full arsenal with velocity, spin rate, induced vertical break, horizontal break, release height, and extension for every pitch type, making it easy to identify strengths, expose weaknesses, and design targeted improvement plans. A 3D spin axis globe lets users visualize spin orientation on an interactive baseball, revealing consistency patterns and tunneling potential that drive pitch design decisions. The command bullseye plots average miss distance from target for each pitch type against pro and NCAA baselines, turning abstract command issues into concrete development goals. Performance trends track velocity, Stuff+, and movement metrics across sessions with visual sparklines, so coaches can see exactly how a pitcher is responding to training over weeks and months. The Trackman Lab provides movement plots showing pitch separation and location plots revealing tendencies in the strike zone, while facility leaderboards rank pitchers by pitch type and a database of 300 professional profiles gives athletes realistic targets to chase. On the hitting side, SpinLab HQ applies the same rigorous methodology with a Hitter Grade built from power, contact quality, consistency, and approach metrics. Every batted ball is plotted on an exit velocity versus launch angle chart with the barrel zone highlighted, showing how often a hitter finds the sweet spot that produces damage. Spray charts visualize batted ball distribution across the field with color-coded contact quality, and batted ball breakdowns show ground ball, fly ball, and line drive rates to inform swing adjustments. Beyond the analytics, SpinLab HQ drives daily development through a programming calendar where coaches schedule throwing activities, drills, bullpen sessions, and recovery work for each pitcher, with completion tracking and notes that sync across all devices in real time. The home dashboard surfaces the metrics that matter most: top performers by Stuff+ and D1 grade, biggest movers over a two-week window, and velocity leaders across the facility. Admin controls let staff import data and upload bullpen videos while players access their own profiles to track progress. Everything syncs to the cloud instantly, so a coach can import a Trackman CSV on one device and have every pitcher's grades, trends, and visualizations updated across the entire facility within seconds. SpinLab HQ is not just an analytics tool but a development operating system that connects data to daily training decisions and turns long-term player growth into a measurable, trackable process.

Know exactly what your hitters are training against. Reactr converts pitching machine speeds into equivalent game speeds — so every rep at practice delivers the reaction time your hitters will actually face in a game. Set a machine speed, set your practice distance, and Reactr instantly shows the game-equivalent velocity and reaction time your hitters are reacting to. Switch to Game Speed mode and work backwards — tell Reactr the game speed you want to simulate and it tells you exactly what to dial into the machine. Used by baseball and softball coaches who want their practice reps to mean something. ——— HOW IT WORKS ——— A pitching machine set to 60 mph at 40 feet doesn't give hitters the same reaction time as a 60 mph game pitch. The distance is different. The math matters. Reactr does the math instantly — so you can stop guessing and start building practices that match the real demands of the game. ——— TWO MODES ——— MACHINE SPEED MODE Know what your machine setting actually simulates. Dial in your machine speed and practice distance. Reactr shows the equivalent game speed, reaction time in milliseconds, and a color-coded difficulty rating. Blue through red — easy to track all the way up to elite velocity. GAME SPEED MODE Work backwards from the game. Set the game speed you want your hitters to train against and your practice distance. Reactr tells you exactly what to set your machine to. Perfect for building progressions that target specific reaction windows. ——— KEY FEATURES ——— EQUIVALENT GAME SPEED See the true game-speed equivalent of any machine setting at any distance. Baseball and softball. Every level of play. REACTION TIME Know exactly how many milliseconds your hitters have to decide and swing. Under 400 ms is elite. Reactr shows you where every rep falls. SPEED COLOR ZONES Blue = Easy to track. Green = Developing challenge. Gold = Competitive speed. Orange = Advanced velocity. Red = Elite. The ring updates live as you adjust. SHARE YOUR SETUP Text your practice configuration to the coach setting up the machine. Machine speed, practice distance, equivalent game speed, and reaction time — one tap, sent. BASEBALL AND SOFTBALL Full support for both sports with separate speed ranges, distance ranges, and game distances. Dial in the official game distance for your specific level of play in Settings. ——— BUILT FOR THE DUGOUT ——— Works completely offline — no WiFi or cellular required No account, no sign-in, no cloud Optimized for iPhone and iPad Portrait and landscape support Free. No trial. No subscription. No catch. ——— WHO IT'S FOR ——— Travel ball coaches. High school programs. College staffs. Batting cage instructors. Anyone running a pitching machine who wants their hitters training at the right reaction speed — not just the right number on the dial. Reactr requires iOS 17 or later. Compatible with iPhone and iPad.
