Apple Watch to be used to push Cook's health agenda
Speaking at Startup Fest Europe, Apple's top executive hinted that the Apple Watch would be the device that in the future, would know everything about you. The device could issue a warning for its owner to see a doctor once the data it analyzes reveals a problem. He compared this to the warning system on a car that tells its owner when it needs maintenance.
Despite Cook's comments, the only changes expected to the next Apple Watch are a bigger battery, FaceTime capabilities and LTE connectivity. That means that we are going to have to wait for future generations of the Apple Watch to provide the features that Cook is talking about. While there are some third party apps that will monitor your sleep and track other health metrics, we are a long way from having your watch tell you when you need to have a check-up.
