From the Apple website:
HealthKit allows apps that provide health and fitness services to share their data with the new Health app and with each other. A user's health information is stored in a centralized and secure location and the user decides which data should be shared with your app.Imagine recording your heart rate using the Apple Watch, then storing that information for use by all your health apps. Pretty cool!
We still need to consider privacy and HIPAA-compliance, of course, but I think this is the wave of the future. Monitoring your health could become as easy texting or checking Facebook, using a device you're already familiar with.
What do you think? Is wellness ready for this kind of technology?
