Mohanan is a Visual and Graphic Designer for Sprim. His Healthbook concept is based on the many rumorsleading up to WWDC and the unveiling of iOS 8. It's not guaranteed that Apple will demo the application during its keynote; however, if it does, it's said to look something like this.
Healthbook keeps and tracks all your vital health parameters in one place, and shows important information and alerts on your lock screen when you need them. To get more out of Healthbook, setup your iWatch and let it track vital information about your body. Make Healthbook work the way you want with hundreds of 3rd party apps from the app store for your iPhone and iWatch.
As rumored, the Healthbook app would feature push notifications and a card interface similar to Passbook.
You can try the demo out yourself by visiting http://www.jayaprasad.com/prototypes/healthbook/ on your iPhone. Also take a look at the video below or hit the link for more information on the concept.
