Rumor: This is the Apple Healthbook app
Apple is reportedly working on a new app called “Healthbook” for iOS 8. Healthbook will be a health and fitness tracking service when it is released. Apparently this is a screenshot of the app above. The app will be able to track steps taken and blood pressure. Healthbook looks similar to the Apple Passbook app, which is used for showing boarding passes and buying movie tickets. Healthbook can store and track data points like heart rate, blood pressure, and oxygen saturation. There is an Emergency Card for storing the user’s names, medications, and doctor information.
