Ultrahuman Adds On-Demand Heart Rhythm Checks to Ring Air and Ring Pro

Ultrahuman has partnered with FibriCheck to launch Heart Scan, an on-demand heart rhythm check for Ring Air and Ring Pro users. The company detailed the feature on Oct. 7. It lets a wearer start a check at the moment symptoms appear, instead of relying only on background analysis during sleep. Engadget

The test runs entirely in the Ultrahuman app and takes 60 seconds. The user sits still, and no new hardware is needed. FibriCheck's algorithm, software trained to spot rhythm patterns, reviews the recording. The result is placed into a PDF that can be shared with a healthcare professional.

Heart Scan builds on Ultrahuman's existing Atrial Fibrillation add-on for sleep monitoring. Atrial fibrillation, often called AFib, is an irregular heart rhythm. The feature is delivered through the Afib PowerPlug, Ultrahuman's name for an optional software add-on. Current subscribers get the new check at no extra cost. Ultrahuman calls AFib Detection its leading PowerPlug, following its 2024 introduction of a smart ring it described as the world's first AFib detection smart ring. WFLA

Availability is limited to supported markets across the UK, Europe, the Middle East and Asia-Pacific. Both current-generation rings are covered. That includes Ring Pro, which Ultrahuman pairs with Jade, software the company describes as the world's first real-time biointelligence AI, alongside other PowerPlugs such as the Caffeine Window for identifying the best time to drink coffee.

The broader context here is the difference between two kinds of checks. Sleep monitoring quietly builds a long-term record, like background recording, but it can miss brief daytime episodes that come and go. Heart Scan reverses that tradeoff. It depends on the user noticing palpitations, dizziness or other symptoms and then sitting still for a clean 60-second recording. That matters because intermittent rhythm problems can look normal during a routine or background check.

In my view, the design choices are practical for bringing wearable data into a clinic. Asking the user to sit still cuts motion noise, the main source of errors for finger and wrist sensors that use light. Keeping capture in the ring and rhythm analysis with FibriCheck separates the two jobs, which makes testing and updates simpler. A PDF sounds plain, but it moves easily between doctors, insurers and health systems without extra software work. It also leaves the medical decision where it belongs, with a clinician reading that short trace alongside history and other data.

Looking at what this means for wearable design, packaging matters as much as sensing. Including Heart Scan in the existing Afib PowerPlug avoids another purchase and keeps overnight and on-demand results in one timeline. That approach will be familiar to enterprise buyers and developers from modular software subscriptions in cloud services. Over the long arc, tools that shorten the gap between feeling a symptom and capturing usable data tend to help both patients and clinicians, as long as expectations stay clear about what one 60-second trace can and cannot show.
