Star.21 is a Fitness Tracker that helps kickstart a healthy lifestyle and cultivates long lasting habits. Based on the 21 days habit formation theory, by achieving a list of milestones in the game, it turns tasks into habits that are second nature. Beneath the diamond-cut surface are 21 LEDs that lights up like stars to display time, progress of your fitness goals - calories burned, distance, steps. The chic design blends tech with fashion, becoming part of your outfit. The soft touch and antibacterial TPU provide a dermatologically safe and comfortable device; the lightweight (18 g) and slim design makes it ideal to be worn throughout the day.
