Get Quick. Get Fast. Get JAWKU SPEED. Numbers don’t lie, and JAWKU SPEED provides the key performance data across speed, agility and reaction time, with unrivaled accuracy in wearable technology. We changed the game. We're still changing it. JAWKU SPEED was intentionally designed with you, the athlete , as our primary focus. Providing a meaningful experience, supported with accurate data capture hasn't existed like this, until now. The best part - while JAWKU is in a class of it's own, it's as simple to use as a stopwatch. Athletes, Coaches and Trainers (and Training Programs/Facilities) across Track and Field, and all Team Sports - this is the game changer you've been waiting for. Compatible with iOS devices, Samsung Galaxy S8 Phones and newer, and Google Pixel 2 Phones and newer.
