This Striiv Band Fitness Wristband is not your average activity tracker. With a two-week battery life and scratch-resistant glass screen, it does more than just track your daily activity and sleep quality. It turns your stats into playing a game, donating to charity and competing with friends. The black wristband also tracks your steps, calories burned, distance and minutes of activity. Check your goal progress throughout the day with bright, easy-to-read LED lights. Sync your smartphone to view colorful weekly and monthly charts of your activity totals. The waterproof wristband also monitors your hours slept and times awakened. View your data on a chart that shows not only the total hours slept each night, but also the quality of your sleep. This item comes complete with a USB cable, quickstart manual and sizing guide.
