Vocal Willow-Hardware

Vocal Willow isn't just an accessibility tool—it's an elite training instrument for every player. Sighted athletes use our sub-millisecond IMU sensor to refine raw mechanics, track impact consistency, and build perfect muscle memory. Because the feedback is entirely audio-first, you never have to break your stance or check a smartphone. Keep your eyes locked on the ball, and let the bat tell you exactly how you hit.
