This slim, stylish bracelet can be worn around the clock. During the day, it tracks your steps, distance, and calories burned. At night, it monitors your sleep patterns and wakes you up silently in the morning. The lights indicate how close you are to your personal goal, helping you stay motivated to move and be more active.
The Flex shows you with LED lights how close you are to your goal. Each light represents 20% of your target. You can set the goal: steps, calories, or distance. The lights motivate you and challenge you to be a little more active every day.
