This smart ring has a feature you won’t find on the Galaxy Ring

The Ultrahuman Ring Air has become the first smart ring to include the ability to detect atrial fibrillation. The feature isn’t part of a simple software update either; it’s the headline feature in Ultrahuman’s new PowerPlugs app store for the smart ring, But as with a lot of modern health and fitness features, there’s a subscription involved.

Let’s talk about the feature first. Wear the Ultrahuman Ring Air, and it will monitor your heart rhythm and look for signs of irregularities — acting as an early warning system for problems that can sometimes lead to serious health concerns. Ultrahuman CEO Mohit Kumar called the feature a “lifesaving technology” and stated that it has been “medical approval in limited markets, and we’re aggressively launching new markets with regulator approval every few weeks.”

Digital Trends asked Ultrahuman which markets the feature will be available in. In an email, Kumar confirmed that the feature will launch first in the U.K., Europe, the United Arab Emirates, Saudi Arabia, and Singapore. He said availability in the U.S. and India is in the works and expected to launch in the next two to three months.

The Apple Watch recently received approval from the Food and Drug Administration (FDA) as a device to assess atrial fibrillation under its Medical Device Development Tools (MDDT) program. The Withings ScanWatch and Withings ScanWatch 2 also have FDA approval for atrial fibrillation detection, and both smartwatches feature an ECG. Other devices with an ECG feature can also monitor for AFib, but the feature may not have been submitted for FDA approval.

PowerPlugs and subscriptions

What about the PowerPlugs app store? Kumar is quoted as saying, “We built PowerPlugs for people to pick and choose what matters most for their health and wellness. Over the next few years, you could expect thousands of applications to be built on top of Ultrahuman’s comprehensive health data platform.”

There are several PowerPlugs available now, with features already seen in the Ultrahuman app, such as Caffeine Window tracking, Cycle tracking, and Circadian alignment. These are free add-ons, but unfortunately, the AFib detection PowerPlug has a subscription attached. It costs $4.90 per month, while a second feature called Cardio Adaptability costs $2.90 per month.

Looking toward the future, Ultrahuman has opened up its heart rate, accelerometer, and body temperature data streams to developers, allowing them to build other tools using its UltraSignal developer platform and make them available in the store. Expect to see apps for free and also more with costs attached.

The announcement of Ultrahuman’s AFib detection and app store comes soon after Oura launched its AI-powered assistant and Circular updated the Ring Slim, as smart ring makers all move to take on Samsung and the new Galaxy Ring.

Siri AI is finally here with iOS 27, and Apple just gave its assistant a serious brain upgrade
Apple's long-promised Siri overhaul is finally rolling out with iOS 27, bringing personal context, onscreen awareness, app actions and smarter Apple Intelligence features.
Siri Ai on iPhone

After years of Siri feeling more like a very polite voice-controlled remote than a genuinely intelligent assistant, Apple is finally rolling out its biggest Siri upgrade yet. iOS 27 is now available, bringing the redesigned Siri AI to compatible iPhones alongside the next generation of Apple Intelligence, with Siri AI initially rolling out in English.

And this isn't just Siri getting better at setting timers. Apple has rebuilt the assistant around personal context, onscreen awareness, app actions and broader world knowledge, letting it understand more of what's happening on an iPhone and actually do something about it. It puts Siri much closer to the ChatGPT- and Gemini-style assistants Apple has been chasing, except this one lives inside the operating system and knows its way around Apple's apps.

Apple has officially started rolling out iOS 27 to iPhone users, bringing the software out of beta more than three months after its WWDC 2026 debut. The developer beta arrived immediately after Apple announced the update in June, followed by the public beta in July. The stable release also comes just days after Apple unveiled the iPhone 18 Pro and iPhone 18 Pro Max on September 9.

The update brings Siri AI, faster app launches and AirDrop transfers, refinements to Liquid Glass, new parental controls, and a long list of smaller quality-of-life improvements. Apple says iOS 27 is available starting today alongside updates for its other major platforms.

The iPhone Duo may be the Nintendo DS replacement I didn’t expect
Delta is preparing dedicated support for the iPhone Duo, potentially turning Apple’s new foldable into a surprisingly capable dual-screen retro gaming machine.

Apple’s new iPhone Duo already has plenty going for it as the company’s first foldable, but there may be another reason to get excited about those two screens: Nintendo DS games. Delta, one of the most popular retro game emulators available on iPhone and iPad, is working on dedicated support for Apple’s foldable. The news comes via RetroDodo, which reached out to Delta lead developer Riley Testut about whether the emulator would take advantage of the Duo’s unusual form factor.

Testut confirmed that dedicated iPhone Duo support is already in the works, although he stopped short of giving it a release date. And this feels like much more than Delta adapting to another new iPhone. The Duo’s folding design could finally give Nintendo DS games the kind of dual-screen setup that regular smartphones have always struggled to replicate.
