Measure your throw speed and bat swing speed with just your iPhone or Apple Watch. Whether you're a pitcher working on velocity or a hitter building bat speed, Arm Speed Analyzer gives you instant feedback.
Track Throw Speed
Strap on your Apple Watch, tap record, and throw. Arm Speed Analyzer measures your arm speed and acceleration through the entire throwing motion, giving you max speed instantly.
Perfect for pitchers tracking velocity gains, outfielders building arm strength, or anyone working on throwing mechanics at practice.
Measure Bat Speed
Hold your iPhone or wear your Apple Watch while hitting to track bat swing speed. See how your swing speed changes across sessions and find your most powerful swing.
Monitor consistency at the cage, compare different stances, and use data to build a faster, more explosive swing.
