Google announced on Wednesday during its Google I/O Developers Conference a new initiative called Google Fit for Android, which will serve as a fitness and health tracking platform.
By using sensors on mobile devices and wearables — like Google's smartwatch collection — users will be able to have a better handle on their various health and fitness-related data to give better recommendations. For example, weightloss app Noom (an early partner of Google Fit) can combine workout data, your weight in real-time (it works with the Withings smart scale) and your eating habits, it monitors your activity and makes suggestions (i.e. when your cookie habit is getting too high, it will intervene).
