It must be reiterated that Google Fit does not focus mainly on the data which is gathered through a slew of wearable devices, although that does play a pretty major role in the scheme of things. Google intends to pave the way for connectivity with other devices, such as connected scales. Not only that, it would also mean that users will be able to provide developers with access to one’s health history, which in turn, can be gleaned to a bunch of other apps that focus on different aspects of life such as exercise, sleep tracking, and weight tracking, among others
The released Google Fit SDK will hold a trio of APIs, which will comprise of the Sensors API, the Recording API and the History API. [Press Release]
