IoT Tech Day 2016 - Take the next step and unleash the full potential of your activity tracker

Nowadays, there are a myriad of health related tracking devices and they come in different flavors and names. Smart phones, smart watches, activity trackers and fitness bands are just a few of these and they are available in abundance. These devices can track a number of health related metrics such as your heart rate, calories burned, steps taken, distance traveled, stairs climbed and sleep quality. They also do a pretty good job of showing this data to the user in a relevant way; either in an app or on your very own web dashboard in the browser. As true developers though…we want to take it a step further and unleash the full potential of the data gathered. And in most of the cases, we can! During this session, you will learn how to access such data, perform your own algorithms on it and build your own UI. Why? Because it’s fun, hopefully even more insightful than the available apps, and ultimately…just because we can. As a use case we’ll be using a Fitbit activity tracker called the Charge HR and take a closer look at the Fitbit API to retrieve its data. Join this session if you want to learn about the possibilities that arise when you tap into the matrix of your own health metrics…and unlock the full potential of your tracking device.
