Health sensors need to go beyond just movement tracking and heart rate. They need to integrate even more bio info into a device. Apple has been making some serious moves in this direction with several new hires in sensor, biometrics and health technologies based on the many iWatch rumors. Apple has already laid the foundation for this move with the M7 motion coprocessor in the iPhone 5s.
Health Central App
Apple has been rumored to be working on Healthbook app for iOS 8. Healthbook would be similar to Passbook and be focused on bringing health related data from multiple sources, together in to a single app. If extended to support second screen features of a wearable and integrate health sensors in wearables, it could provide a compelling selling point for wearables.
Health App Ecosystem
There really are only 2 viable and successful app ecosystems in the mobile space: Apple’s iOS and Android. And the advantage of a well established and mature ecosystem is immeasurable. Besides the technology and infrastructure available, the vast amount of experienced developers and apps that can be leveraged in health apps and wearable health related devices immediately, is mind blowing.
