DribbleUp Smart Balls are hand-stitched and official size. Available in soccer and basketball versions, they track your performance using any smart device. The soccer ball connects to the DribbleUp app, and provides a virtual trainer to take your skills to the next level. Live audio and virtual cones provide instant training feedback and track your progress. Drills are suitable for players of all levels and ages, and can be used indoors or outdoors. The basketball works the same way, and measures your crossover speed, dribble hesitation, and endurance level. It also tracks your dribbling live with an interactive dribble speed meter. Both balls require no batteries or charging.
