watchOS 27 is coming next week, and 3 rumored features have my attention

WWDC kicks off Monday, June 8, and alongside iOS 27 and the new Siri, Apple will give us our first look at watchOS 27. The early word is that this is a quieter year for the Apple Watch, but a few rumored features still have me genuinely curious. Here are the three I'm watching for.

Heart rate tracking gets smarter, and blood pressure might get an upgrade

Mark Gurman reported in his Power On newsletter that watchOS 27 will bring improvements to the Apple Watch's heart rate tracking. He didn't say much beyond that, which is a little frustrating, but the part that stands out to me is that these upgrades are expected to work on the hardware people already own. Software that makes your current watch better is always a nice surprise.

There's a second health angle worth flagging. A recent Digitimes report says a new high blood pressure notification feature is under review by the FDA. That regulatory step is usually a strong signal that a feature is close, so I'd be surprised if this doesn't land in watchOS 27 in some form.

Here's the thing: the Apple Watch has slowly become one of the most quietly important health products Apple makes, and these are exactly the kind of incremental wins that add up over a few years. I'd love to see Apple lean into this even further.

A Modular Ultra watch face for the rest of us

This is the one I'm most excited about. Rumors point to a new face in watchOS 27 described as a simplified take on the Modular Ultra design, which until now has been exclusive to the Apple Watch Ultra.

According to Gurman's reporting at Bloomberg, the new face would keep the oversized clock from the Ultra face but strip out the busier elements: the big central complication, the row of three smaller complications above the time, and the information wrapped around the bezel. What's left is a large clock filling the top two thirds of the display, with a single row of three smaller complications underneath. In other words, a cleaner Modular Ultra built for the standard Series watches.

I've wanted something like this for a long time. Modular Ultra is my favorite face Apple has ever shipped, and the only reason I haven't used it daily is that it never came to the Series models. If a stripped down version finally makes the jump, that alone might be my favorite watchOS 27 change.

A more capable Siri on your wrist

The headline Siri overhaul will obviously shine brightest on iPhone, iPad, and Mac, where the full chatbot style experience is expected to live. But the new Siri should benefit the Apple Watch too.

There's no word yet on whether watchOS will get a standalone Siri app like the one rumored for iPhone. Honestly, that matters less to me than the basics. Siri on the wrist is the place where reliability counts most, because you're usually asking for something quick while your hands are full. If the new Siri can simply handle more complex requests and stop misfiring, that's a real upgrade.

What else to expect

Outside of these three, not much is known. Bloomberg has described watchOS 27 as focused largely on stability, performance, and smaller refinements, which tracks with what we're hearing about the rest of the lineup this year. That's not a bad thing. After a few busy cycles, a release that just makes everything run better has its own appeal.

We'll know for sure when Apple takes the stage on June 8. What watchOS 27 feature are you hoping to see? Let me know.
