Designed to be both fast and simple to use, the prototype we tried out this week was ultra-light, and thinner than the Speck case on one of our iPhones. Readings are done with your hands in a comfortable position, and the health tracker was able to return our vital signs as well as a fancy ECG graph of our heart in just a few seconds. Out of the box, youll be able to pair it with your Wi-Fi scale and fitness tracker, so you can keep an overall picture of your health in the same place.
