The smart sleeve that corrects your technique in real time through haptic feedback. Train alone. Improve faster.
Video review and smart balls only show mistakes after the fact. The neurological window for correction has already closed.
Without real-time intervention, every solo practice session reinforces the exact habits athletes are trying to break.
The athletes who need feedback the most are priced out of getting it. Talent shouldn't have a pay wall.
Betta's dual motion sensors map your personal best technique. Instead of comparing you to a textbook, it learns your Optimal Form Signature — the version of your shot that's uniquely, measurably yours.
100 readings per second from elbow and wrist sensors detect the moment your form drifts from your personal best. Nothing slips through — whether it's your elbow, your wrist, or the relationship between the two.
Four small vibration motors sit at the top, bottom, left, and right of your arm. Elbow flaring out? You'll feel a gentle pulse guiding it back in. The vibration tells you exactly which direction to adjust — and when it stops, you've nailed it.
We're building something that's never existed before. Drop your email and we'll let you know the moment it's ready.
Every rep without feedback is a rep that reinforces bad habits. Betta makes sure every rep counts.
