There's been plenty written about Apple testing a major initiative for iOS 8 in the form of the Healthbook app, a Passport inspired design that will interact with hardware (iPhone 6, wearables, iWatch) to provide critical health information. These could include, but are not limited to: Emergency Card Bloodwork Heart Rate Hydration Blood Pressure Activity Nutrition Blood Sugar Activity Nutrition Blood Sugar Sleep Respiratory Rate Oxygen Saturation Weight We walk around not knowing a fraction of this information. Having access to such vital data can certainly impact our everyday lives. We might pass on that donut or take every opportunity to reduce our stress. Not hydrated enough, there's a notification that tells you to drink more water. If this stuff all works as planned, it will be a new era of self-monitoring. I for one am going to enjoy these last few months of being unhealthy and free of any monitoring. Coming the release of iOS 8, things could change. What are your thoughts on Healthbook?
