Getting into shape, losing weight and moving more each day are all really tough to do. An activity tracker can help. Seeing how much exercise you get day-by-day and weeek-by-week, can motivate you to start taking the stairs more or walking an extra lap around the block. At the very least, it will make you more mindful of your present activity level, which is a huge first step to getting fit. 0.91" OLED Screen Built-in Bluetooth 4.0 allows you to connect to external Bluetooth enabled devices Android 4.3 compatible Compatible with iPhone 4S, IOS 6.0 and above Tracks steps, distance, calories burned and active minutes Monitor how long and well you sleep Wake up with a silent wake up alarm LED lights show how your day is staking up against your goal Slim, comfortable and easy to wear Incoming call alert Water proof Take pictures from your smartphone through the built-in remote control on your wristband Rechargeable battery (80mAh) Reach up to 49 ft.
