Ultra Age contributors

Ultra Age is a science-backed aging marker powered by your physiology. It’s a single insight combined from your Brain Age, Pulse Age, and Blood Age. This insight can help you track how lifestyle changes, sleep, exercise, and nutrition impact your aging trajectory.

Brain Age

Calculated using Ultrahuman’s Brain Waste Clearance marker, which estimates how your brain resets itself during deep sleep. Poor sleep or disrupted HRV can impair this process and accelerate neurological aging. A lower Brain Age means stronger glymphatic clearance, better neural recovery, and improved long-term brain health.

Pulse Age

Ultra Age incorporates arterial flexibility analysis via the PPG sensor to understand how your body is aging. Arterial stiffness is associated with poor cardiovascular health and carries an increased risk of heart disease and stroke. But it can be improved with lifestyle interventions, including diet and exercise. 

Pulse Age combines arterial flexibility with heartbeat stability, blood flow speed and smoothness, as well as pulse quality data, for a deep look at how your vascular system is aging. A lower Pulse Age means your arteries are in good shape.

Blood Age

Available if you’ve completed a Blood Vision test (US and India), Blood Age is your body’s internal health scorecard, derived from key blood biomarkers like CRP (inflammation), LDL/HDL (lipid profile), glucose (metabolism), and WBC (immune balance). 

It’s a composite measure of over a hundred biomarkers that analyze how your organs, cells, and systems are performing. 

A younger Blood Age suggests healthier metabolic function and a lower risk of age-related disease.

Track your pace of aging

Alongside your current Ultra Age, you’ll also see your pace of aging. This scale reveals whether you’re aging faster or slower than your chronological age, based on your profile.

The pace is updated as your underlying contributors shift. If your brain and cardiovascular recovery improve, you may see your pace drop, indicating a reversal in stress-related aging. If sleep debt accumulates, HRV drops over sustained periods, and a Blood Vision test reveals inflammation markers, your pace of aging may speed up, offering a prompt to intervene early.

Where to find Ultra Age

You’ll find the Ultra Age tile in the Ultrahuman Ring app homepage. It will show your overall Ultra Age and your pace of aging.

You can tap on the tile to view contributors such as  Brain Age, Cardio Age, and Blood Age, and their weightage. This also includes your current pace of aging.

Tapping on any contributor opens a detailed page showing top influences to your Ultra Age score, and what you can do to improve it.

Summary

Aging isn’t a static number. It responds to sleep quality, stress levels, cardiovascular strain, and nutrition. Ultra Age brings these signals together to help you track your health trajectory in real time, not just in years, but in meaningful physiological changes.

With Brain Age, Cardio Age, and Blood Age feeding into a single, transparent metric, Ultra Age gives you a more complete view of how you’re doing – and where to focus next.

Those first months as a parent are an incredibly special time. However, sleep can become a scarce commodity. Some parents have it worse than others, but most will go through a period of rough sleep at some point in the first year.

Sleep deprivation from multiple awakenings can affect mood, cognitive performance, and energy levels, just when you need those things the most. 

The New Parent PowerPlug tweaks the Ultrahuman Ring AIR’s sleep score and recovery algorithms to account for disrupted and irregular sleep patterns. The aim is to help new parents get a true picture of their sleep duration and make informed decisions to boost recovery and reduce sleep debt.

How it works

The New Parent PowerPlug on Ultrahuman Ring AIR applies flexible sleep timing and recovery thresholds, giving you more accurate, supportive scores, no matter how many feeds you gave in the night. 

When you get good quality rest, no matter what time of day or night, you’ll see that reflected in the sleep and recovery markers within the Ultrahuman app. If you get poor sleep scores, or you’re racking up sleep debt (accumulated missed sleep over time), you can make informed decisions on prioritizing naps.

Benefits of the New Parent PowerPlug

A true reflection of your sleep score

The New Parent PowerPlug applies flexible sleep timing and recovery thresholds, giving you a more accurate score, even when your sleep looks unconventional on paper. It de-prioritizes deep sleep, sleep efficiency, restfulness, and REM sleep from your overall sleep score to enable users to get a fairer assessment of their sleep.

Encouragement, not criticism

New parents don’t need added pressure, so the New Parent PowerPlug offers encouragement and bigs up the mini-wins. The PowerPlug will also have a dedicated tile on the dashboard, which shows your baby’s development phase.

Gentler movement nudges

When the New Parent PowerPlug is active, the Ultrahuman Ring AIR reduces the daily goal to 7,000 steps to better reflect realistic activity levels during this phase. It also removes workout frequency as a contributing factor to overall recovery. 

However, regular movement is still important. So the Ultrahuman Ring AIR rolls its workout frequency benefits into step count scoring. That means making time to get extra steps in will offer a boost in recovery.

Finally, you’ll see “Baby Wearing” in the workout list, so you’ll get extra benefit from strapping your baby to your front and going for a walk.

More reward for naps

In the face of sleep deprivation, short naps can have huge benefits for mood, concentration, and cognitive performance. Our improved Nap Detection V2, trained on over 1 million anonymous naps, precisely tracks short rest periods and incorporates them into your Recovery Score and Sleep Debt calculations in real time. And with the New Parent PowerPlug enabled, naps will have a bigger impact on your recovery. 

Conclusion

New Parent PowerPlug tweaks and refines the algorithm to help moms and dads deal with this challenging and brilliant time of life. By offering a true reflection of sleep and a supportive experience, it’s designed to nudge users to maximize sleep opportunities for a cognitive and energy boost when they need it most.

Context is everything when it comes to understanding your sleep, recovery, and overall health. Accurate data is powerful, but knowing why your biomarkers have changed is where real insight begins.

That’s why Ultrahuman created Smart Tags – a simple, powerful way to add meaningful context to your sleep and recovery data.

What are Smart Tags?

Smart Tags help you connect the dots between your habits and your health. They’re a way to annotate your Ultrahuman Ring AIR data with real-life context and start to build a deeper understanding of your body.

A heavy late dinner, a tough workout, a new supplement, or a couple of drinks – you can now understand what’s helping and what’s holding you back.

Ultrahuman now includes a library of hundreds of predefined tags to annotate your data. We’ve made Smart Tags as frictionless as possible, and many are automatically detected using your unique biomarkers and prompted for you to confirm – that’s what makes them so smart. 

How Smart Tags offer frictionless context

Smart Tags

Smart Tags are automatically detected and suggested based on changes in your biomarkers. Just confirm with one tap in the Ultrahuman app to apply the suggested tag to your data.

For example, a late drop in heart rate, a higher resting heart rate, and elevated body temperature might trigger a “late-night meal” tag. You can always tweak the tag if there’s a better match.

Here are a few examples of Smart Tags available at launch:

• Late-night meal
• Fever detection
• Late stimulants

And there are even more on the way, including travel, jetlag, sleep environment tags, and activity levels.

Auto Tags

Auto Tags help you understand the impact of sleep patterns and disruptions on your health. Examples include:

• Stayed up late.
• Overslept.
• Immune system overload.
• Recovery sleep.

These require no input and are automatically applied from patterns in your data. 

Manual Tags

Smart and Auto Tags are designed to make annotating your data as frictionless as possible, but you’re still in total control. Search and apply any of the hundreds tags at any time.

Examples could include tagging a new supplement, period cramps or medication.

Where to find Smart Tags

There are multiple ways to quickly and easily add tags within the Ultrahuman app:

• You can confirm suggested Smart Tags from the app, or quickly re-tag from the Tags library.
• Add or review Auto Tags from the Timeline.
• Review contextual tags, or add manual tags with time slots within Sleep or Recovery cards.

All tags will show up on the timeline within the Ultrahuman app. But Smart Tags are all about context, so they will be displayed near metrics they influence to help you connect the dots. 

For example, cold plunge aids recovery, so it would be shown next to this score. 

Likewise, having an evening cocktail could impact your sleep, so this tag would show up next to your sleep data.

Why use Smart Tags?

Tagging offers unique insights into how your body reacts to all manner of situations and stimuli – from sauna and yoga to medications and supplements.

Once you’ve tagged a few times, you’ll start seeing trends and patterns of how your body reacts. That insight enables you to understand how certain choices affect your recovery, sleep, and overall performance.

Over time, you’ll also see insights from the community, such as how many users displayed a positive or negative response to a specific tag.

And you’ll also be able to identify correlations. If you’re experimenting with supplements such as magnesium for sleep, tagging can provide reassurance about whether you’re seeing benefits.

Conclusion

Smart Tags connect the dots between your data and real life, and add the context needed to understand your sleep, recovery, and overall health. 

By layering in the why behind changes in sleep and recovery, you unlock deeper insights and more actionable feedback.

It’s not just about tracking what’s happening. It’s about understanding what’s driving it, so you can make smarter choices.

Brain Waste Clearance

The brain produces metabolic waste throughout the day, including amyloid beta and tau proteins, which are cleared by a process called glymphatic clearance. If allowed to accumulate, this waste is associated with cognitive decline and neurodegenerative conditions like Alzheimer’s disease.

The Brain Waste Clearance signal is based on a combination of sleep, recovery, and temperature markers, reflecting the conditions under which glymphatic clearance is known to be most active.

The result is a groundbreaking marker for brain recovery, only on Ultrahuman Ring AIR.

Read more in our Brain Waste Clearance blog.

Caffeine Window upgrade

Ultrahuman’s much-loved Caffeine Window feature has just been upgraded. Now, it’s personal with effortless tagging, real-time body caffeine levels, adaptable cut-off times, and detox advice. 

Logging has been redesigned to be quick and seamless. The new Caffeine Bar includes a vast library of drinks, and your most-used beverages stay pinned for one-tap logging.

Most notably, Caffeine Window now syncs with Ultrahuman’s Brain Waste Clearance data. It analyzes your previous night’s sleep, looking at deep sleep, HRV, temperature, and more, to determine how well your brain cleared toxins. If clearance was strong, you’ll get a Caffeine Bonus with a later cut-off time. If it was poor or fragmented, the app may recommend an earlier cut-off or even a full Caffeine Detox to support recovery.
