Apple’s Changes to HealthKit Could Hint at iWatch Sensors

iwatch-roundIn the absence of any official word from Apple, the conventional wisdom surrounding the iWatch has been more or less made up by bloggers hoping to have just enough insight to say they have predicted what we’ll see when the device finally launches later this year. That’s what’s happening here: Apple has made some changes to its HealthKit app, still in beta, which might hint at a possible sleep – or caffeine – sensor built into the iWatch.

According to a post on 9to5Mac, Apple has added “caffeine” to HealthKit’s nutritional tracking categories. That means that other health-tracking devices that keep track of a user’s caffeine intake will have a place to send that data. One such device for which this feature sounds made is the Vessyl smart cup, which just last week hired on an Apple design veteran. Coincidence?

As to where the iWatch enters into this equation, well, that’s mostly speculation on my part. However, it’s entirely possible that adding caffeine information to Health could signal that the iWatch will offer similar functionality to that provided by other activity trackers. One such device, the Jawbone UP, has a caffeine tracking app that allows users to log how much coffee they’re taking in. The UP can then analyze a user’s reaction to that intake and give users an insight into how the caffeine has affected them.

The Jawbone UP is a basic fitness band, so it stands to reason that the iWatch will do everything the UP can do – and more. Moreover, reports have been coming for months about various health-related innovations Apple may be cramming into its devices – like sensors that can predict heart attacks. Given the Vessyl’s ability to analyze a substance’s caffeine content, and Apple’s penchant for imbuing its technology with magic, it’s entirely possible that the iWatch will somehow be able to read the caffeine flowing through your bloodstream and report that data back to the HealthKit app.

Recently a pocket-sized molecular spectrometer, called the SCiO, found massive success on Kickstarter. That device boasts the ability to know what’s going on underneath the surface of food, beverages, plants, and animals. Would anyone be really that surprised if Apple has similar technology built into the iWatch?
