Leaked information has revealed potential details of Apple’s health and fitness application, Healthbook, which could be capable of recording an array of information to monitor the state of the human body.

Details suggest that Healthbook will record activity levels, nutritional information, weight and sleep patterns, as well as heart rate, blood pressure, blood sugar levels, respiratory rate and oxygen saturation.

It is believed that Apple will give its users the opportunity to retain all of this collected data on an Emergency Card, which can be presented to medical or health professionals should the user be unable to speak or communicate.

The app could be launched alongside Apple’s new iOS 8 operating software later this year, as the company looks to challenge the likes of Nike and Samsung, which have already sought to firm up their positions in the health and fitness markets.

One detail that still remains a mystery is how all of the data will be collected, with the likes of blood pressure and sugar levels unobtainable by devices such as the iPhone.

However, more complex data could possibly be collected through a group of sensors linked to a wearable device, such as a smart-watch.

Enthusiasts believe that the Healthbook application could somehow be linked to an iWatch, which is also thought to be coming to the consumer market in the next year, with other more established wearable devices also compatible with the Healthbook application.
