Electronics analyst Sun Chang Xu of Chinese site Electrical Engineering Times pretty much confirmed earlier speculations that the upcoming Apple iWatch will contain sensors which will allow users to track health related metrics like O2 (oxygen) levels and heart rates.

This confirmation comes on the heels of earlier rumors that speculated Apple will indeed enter the healthcare market by including fitness/health tracking capabilities in its smart watch.

Those earlier rumors said that the Cupertino-based company is working on an app called Healthbook which will be used to keep track of a user’s blood pressure, heart rate, calories burned, and more. The iWatch would naturally be used to collect this data, while the application would provide useful and actionable metrics, both to users and their physicians.

It is said that Apple will announce the iWatch later this year.
