Soon, your phone will know more about your health history and fitness goals than your doctor does. Imagine a day when your phone has all of your health information. It knows your goals, your time horizons and what activities you need to focus on to achieve those goals. It knows your schedule, whether you like to do things alone or in groups and who you like to train with. It knows what you eat, how much you’ve slept and all of your vital signs in real-time.
