Ultra Age lands on Ultrahuman Ring Air and it looks familiar
Ultrahuman’s new Ultra Age feature has landed in the iPhone app, giving you a way to track how your body is aging. It pulls together Ring Air data from your sleep, heart signals and blood biomarkers to estimate a number that’s meant to reflect your “true” biological age.
It looks familiar but works differently
When I first saw the new Ultra Age tile on the app’s homepage, I couldn’t help but notice how much it visually resembles Whoop’s Health Span score. Same kind of dial and headline metrics. But while they look almost interchangeable at a glance, they aren’t doing the same thing under the hood.
Each company has its own way of crunching the numbers. Whoop leans heavily on cardiovascular recovery and sleep. Ultrahuman adds a blood biomarker layer, if you’ve done their Blood Vision test. Even the definitions of terms like “Brain Age” or “Pulse Age” aren’t interchangeable across platforms. So I wouldn’t compare them side-by-side too seriously.

Still, the value here isn’t in the exact number. It’s in tracking the direction. If your Ultra Age starts dropping steadily over time after a few lifestyle tweaks, then maybe those changes are doing something useful. If it jumps up after a bad week of sleep or a few nights of heavy drinking, that’s also worth noting.
Brain, pulse, and blood all rolled into one score
Right now, my app is only showing me Brain Age. Pulse Age is greyed out, and Blood Age doesn’t appear at all since I haven’t done the blood test. From what I’ve seen in social posts, I’m not alone. A bunch of people are in the same boat, so it looks like the system needs time to gather enough data from the smart ring to activate each component.
The Brain Age number comes from Ultrahuman’s marker for glymphatic clearance, which basically tries to estimate how well your brain resets itself during deep sleep. If your HRV is low or sleep is broken, that number can creep up. Pulse Age uses PPG data to estimate arterial stiffness. It combines several factors like heartbeat stability and pulse waveform to paint a picture of your cardiovascular health.
The Blood Age part is the most complex, drawing from over 100 markers in the blood panel. But that’s only available in the US and India for now. And you need to do an actual blood test. So depending on where you are and how much you’ve opted into the broader Ultrahuman ecosystem, your Ultra Age might be a full composite or just a partial view.
It updates weekly, not daily
Just like on Whoop, the metric is not going to jump around from day to day. Instead, it works off rolling weekly averages. That helps smooth out temporary blips and gives a better sense of where your health is heading over a longer stretch of time. You’re not going to see a spike just because you had one bad night. But you will if late night partying turns into a habit.
The pace of aging part is a nice addition too. It tells you whether you’re currently trending faster or slower than your chronological age. Your Ultra Age might stay the same, but your pace can change, nudging you toward improvement before things get worse
No joy for Android users
At the time of writing, the Ultra Age feature hasn’t rolled out on Android. It’s visible on my iPhone, front and center, but not on my Android phone. So if you’re not seeing it, you’re not missing something. It’s just not live yet on that platform.
Like a lot of things in the wearables space, this feature is a mix of solid ideas and slightly fuzzy execution. The visuals are clear. The concept makes sense. But the numbers are only as good as the inputs, and those can vary from day to day and person to person.
I wouldn’t hang too much on the absolute values here. But as a gentle nudge to pay attention, or as a way to spot trends over time, Ultra Age might be useful.
