Apple considers making its own health-monitoring processors

Apple could be shaping up to take more of its technology creation in-house, if rumors based on a recent job listing are to be believed.

Health sensors have become a large part of Apple’s hardware over the last few years. The Apple Watch Series 3 comes with an optical heart-rate sensor built in, as well as a particularly impressive suite of fitness tracking tools, while the iPhone’s Health app was perhaps a little too helpful when it was first released. Back in 2017, Apple proved it was serious about filling out its fitness chops when it acquired Beddit, a successful sleep-tracking app.

It’s common with this sort of health-tracking to have a specialized processor dedicated only to the task of monitoring heart rates and other data — otherwise known as an “application-specific integrated circuit”, or “ASIC”. This chip takes the load off of the main chip, leaving the main processor to power other parts of the device.

Apple has previously bought these chips from a third-party supplier, rather than creating its own — having purchased ASICs from Broadcom for the Apple Watch Series 3. However, it seems Apple is ready to commit itself to further health-related features by bringing the construction of these dedicated processor chips in-house.

The job listing in question, posted on July 10, is for a Sensor ASIC Architect to work with Apple’s Health Sensing Hardware team. This role is centered around “develop[ing] ASICS for new Sensors and Sensing Systems for future Apple products” — making it seem pretty clear that Apple is looking to bring this particular part of the Apple Watch under their own manufacturers.

There are a few advantages to such a move. By developing and manufacturing its own specific chip for health monitoring, Apple would be able to wed the hardware and software together in a much more intimate fashion, increasing efficiency. In addition, it would also shore up Apple’s defenses against imitators, as the chip would be able to be patented as Apple’s own hardware, rather than being open to other companies — as a third party’s tech would be.

Most excitingly, this development could be an advancement of a story from April 2017 that claimed Apple was working on the so-called “holy grail” of life sciences — noninvasive technology that could monitor blood glucose levels constantly.

10 colors I wish Apple made for the iPhone 15 and iPhone 15 Pro
iPhone 15 Pro in a red color.

Apple finally revealed the iPhone 15 at its “Wonderlust” event on September 12. This lineup includes the iPhone 15, iPhone 15 Plus, iPhone 15 Pro, and iPhone 15 Pro Max. There were other products announced during the event as well, but the iPhone 15 series is the biggest of the bunch.

However, Apple’s really been dropping the ball lately in terms of device colors. This year is especially bad with the very pastel and muted colors of the iPhone 15 models, not to mention the various shades of gray for the iPhone 15 Pro variants.

The Apple Watch Ultra 2 is (almost) exactly what I wanted
A promotional image of the Apple Watch Ultra 2.

The Apple Watch Ultra 2 announcement from Apple's iPhone 15 event needs some thinking about before it makes sense. Why? At first, it looked like a product barely deserving of the name due to a disappointing list of upgrades, the addition of only a few new features, and the fact that it has exactly the same look as last year’s model.

This is all factually correct, but I’m about to explain why it was to be expected — and why it doesn’t matter at all.

Everything Apple didn’t announce at its iPhone 15 event
Apple's September 2023 event Tim Cook

Yesterday's iPhone 15 event revolved solely around the iPhone 15/iPhone 15 Plus, iPhone 15 Pro/Pro Max, and Apple Watch Series 9 (along with Apple Watch Ultra 2). As a result, no new iPads, Macs, or audio products were announced. This news isn't surprising, and the omissions suggest another Apple event may occur before the year's end, although this has yet to be confirmed and may not happen for a few weeks.

There are a lot of would-be Apple products that could make appearances in the coming weeks or months — but weren't shown at today's event.
