The Apple Watch is in every sense a smart watch - it's as powerful as an iPod Touch and yet a fraction of the size. Interestingly though, the Apple Watch actually started life as one of the most advanced fitness trackers in the world.
According to a new report by the Wall Street Journal the Apple Watch was originally packed with a variety of advanced health sensors including one that could measure conductivity of the skin.
The tech giant was also working on ways to detect blood oxygen levels however -- as the WSJ reports -- it soon became clear that the project was becoming something of a financial 'black hole' and so Apple cut the program and instead changed its focus towards the Apple Watch being a full smart watch.
Earlier this month Apple CEO Tim Cook spoke about the importance of exercise saying, 'sitting is the new cancer'.
Cook went on to talk about how Apple wanted to use the Apple Watch as a means of changing the way people live their lives, across all aspects from communication to health.
At present the Apple Watch comes with a heart-rate sensor as well as a fully-integrated fitness tracking app that'll measure steps and even remind you to move if you've been sitting down for too long.
If you're thinking that Apple's health focus has been lessened however than think again, a report by Reuters last year in fact cited that Apple was simply delaying the enhanced features for the Apple Watch 2.
