Ultrahuman Ring Air now measures Cardiovascular Age

Ultrahuman has introduced a new Cardiovascular Age metric for its Ring Air smart ring. This feature enables users to gauge their cardiovascular health relative to their chronological age, providing insights into potential risks and areas for improvement.

Accessible via the VO2 Max tab within the Ultrahuman smartphone app, the Cardiovascular Age metric displays a numerical value that can align with, fall below, or exceed the user’s actual age. A lower cardiovascular age indicates optimal heart health, while a higher value may signal the need for lifestyle modifications or further medical evaluation. Which means you want to aim for as low a value as possible.

There is no chart or anything like that in the app – just the current Cardio Age. Hopefully the company will introduce that at a later stage as it would be useful to keep an eye on how the metric has changed over time.

Here is a screenshot.


While the exact methodology behind the Cardiovascular Age calculation remains undisclosed, it’s likely that Ultrahuman utilizes photoplethysmograph (PPG) signals collected by the Ring Air. This technology measures variations in blood volume within the finger, providing information about arterial stiffness and pulse wave velocity – crucial indicators of cardiovascular health and aging.

One of many updates

This latest feature from Ultrahuman aligns with a growing trend in the wearables market toward personalized health insights, particularly those related to heart health. Notably, competitor Oura recently introduced a similar Cardiovascular Age feature for their smart ring, underscoring the increasing importance placed on heart health monitoring by consumers and manufacturers alike.

As noted in my hands-on review of Ring Air, The Ultrahuman Ring Air is a compelling entry in the smart ring market. It boasts a comprehensive and insightful app, accurate tracking of key health metrics like HRV and sleep, and innovative features like the circadian clock. Its comfortable design and impressive battery life further enhance its appeal. While areas like step count accuracy and app simplification could be improved, the Ring Air’s educational approach to health data and absence of subscription fees make it a worthy investment for those seeking a deeper understanding of their well-being.

What I also like is the regularity at which updates to the app are rolled out. Every few weeks, it seems, a new feature lands. I personally am not seeing the new Cardio Age metric, but other users are reporting on social media that they are. Ultrahuman has also announced on Twitter that the feature is live. Hopefully it will be available to all in the coming days.

The company says they are also working on a major upgrade for heart rate monitoring during workouts and breath work sessions. This is “expected to go live super soon”.
