This is the device that combines the health tracking features of a fitness monitor with the functionality of a smart watch. Similar to a Fitbit, it monitors your heart rate, blood pressure, body temperature, blood oxygen, and can record workouts, steps taken, and calories burned. During the day it reminds wearers when it's time to hydrate or get active, and at night it monitors sleep quality. As a smart watch, it pairs with a device to alert users to incoming calls on the watch's 1.4" color touchscreen. Additional apps include a stopwatch, alarm clock, weather updates, and streaming music. With an IP67 water-resistance rating and two interchangeable wristbands. Charges via USB; a full charge provides up to five days of power. Fits wrists up to 9 1/2".
