Nuvo vs Neko Health: Daily Biological Age App or $499 Clinic Scan?

Pick Neko Health for a $499 in-person scan in SoHo. Pick Nuvo for a daily 21-biomarker bio age on iPhone. Complementary, not substitutes.

Written by the Nuvo Longevity editorial team at Firefly Labs LLC.

Choose Neko Health if you can get to a clinic and want a clinician-led, radiation-free visit of about an hour: skin imaging with mole mapping, heart and circulation checks, body composition including visceral fat, grip strength, eye pressure, and an on-site blood panel of 50+ biomarkers, for $499 self-pay. Choose Nuvo if you want a daily biological age on the iPhone and Apple Watch you already own, from 21 biomarkers — HealthKit wearables plus optional labs — computed on the phone, with no account, at $4.99/month or $24.99/year. They are complementary, not substitutes. Neko is a periodic deep baseline where a clinic is open. Nuvo is the daily feedback loop between scans, including for anyone who cannot get to SoHo.

What each product actually sells

Neko Health: a clinician-led scan in a clinic

Neko Health, founded by Hjalmar Nilsonne and Spotify’s Daniel Ek, opened its first US clinic on 24 September 2026 at 300 Lafayette Street in SoHo, New York. The opening release says more than 25,000 New Yorkers had joined the waitlist, and that more than 100,000 people had already been scanned across Sweden and the UK. The same release prices the hour at $499 and calls SoHo the first of many planned clinics: additional New York locations and a Miami clinic are expected to follow, with Washington, D.C. and San Francisco also planned. eWeek (18 August 2026) reported the same $499 address, the same expansion list, and a $700 million Series C dated 15 July 2026. The opening release itself describes that round as led by Lightspeed Venture Partners and co-led by O.G. Venture Partners.

The visit is in person. Neko’s release says the scan takes roughly 30 minutes, then about 30 minutes with a clinician, and that the visit is radiation-free. What the release and the US health-scan page say is measured:

• Skin. A 360-degree skin exam. The opening release says about 6,000 images from cameras in the visual spectrum and from thermal cameras. The scan page says moles are indexed and that concerning spots are reviewed by a Neko dermatologist.
• Heart and circulation. A cardiovascular assessment. Neko’s US medical terms name blood pressure, electrocardiogram (ECG), and oxygen saturation among the non-invasive tests. The scan page describes the heart’s electrical activity read alongside arterial health, and a check of circulation through the smallest vessels at the feet, beyond a single arm-cuff reading. A 5 October 2026 write-up of the New York visit describes blood pressure at several sites and that foot-vessel check as laser-based microcirculation. Neko’s UK scan-facts page lists brachial and ankle blood pressure on both sides. That is the published UK method list. We are not inventing a SoHo sensor count the US pages do not print.
• Body composition. The opening release says a detailed body-composition analysis. The US scan page includes visceral fat, explained by the clinician in the context of metabolic health.
• Grip strength and eye pressure. Both are named on the US scan page and in the US medical terms. The scan page frames grip strength as a measure of functional strength and eye pressure as a screen for glaucoma risk.
• Blood. On-site testing of 50+ biomarkers with same-visit results. The scan page names heart health, metabolism, immunity, and inflammation among the areas covered. We use Neko’s “50+”. We do not swap in a different count from a later retelling.

What the scan is not: Neko’s US scan page says the devices use no X-rays and no CT. The visit is not marketed as a full-body MRI. The 5 October 2026 write-up says the New York scan does not include MRI, CT, or ultrasound, and so does not image organs, coronary calcium, or the brain. Neko’s UK scan-facts page does list a 4D cardiovascular ultrasound system among devices used in the UK, so this page does not turn “no ultrasound” into a worldwide claim. For the US comparison, the line Neko prints is the one to use: radiation-free, no X-ray, no CT, and not an MRI exam.

Payment is self-pay. The medical terms say Neko does not currently accept insurance. The financial responsibility agreement (last updated 21 September 2026) is explicit: you pay Neko directly, Neko will not bill commercial insurance or government programs including Medicare and Medicaid, and payment is due when the service is provided. Accepted methods include cash, personal check, and major credit and debit cards, including HSA/FSA cards. The opening release also says Neko accepts HSA and FSA payments. The agreement adds two limits worth keeping: HSA/FSA eligibility can differ by plan, and an itemized receipt can be used to ask a commercial insurer for reimbursement at your own risk. Neko does not promise that an insurer will pay, and it asks members not to submit the visit to a government health program. eWeek reported the same self-pay model.

After the appointment, the opening release says results live in the Neko Health app on iOS and Android. The app stores scan history, tracks changes over time, and can sync daily data from wearables such as Oura or Whoop via Apple Health. That is a clinic record plus wearable context for the clinician. On the US pages we checked, it is not a daily biological age score. We did not find a Neko page that says the scan computes one, so this comparison does not invent one.

Neko is a clinic, and the medical terms draw a clear boundary. Neko says it is not a full-service practice, not a primary-care substitute, and not a place that treats conditions found during the visit. If something needs follow-up, Neko can suggest further investigation and, with consent, share findings with your physician. The opening release names referral relationships in New York, including Columbia University Irving Medical Center, Schweiger Dermatology, and Mount Sinai Health System, and says members can also be referred to their own clinicians. The scan is a baseline and a conversation with a clinician. It is not a number that recalculates on an Apple Watch every morning.

Nuvo: a daily 21-biomarker score

Nuvo Longevity (App Store: Nuvo: Longevity Coach, id 6762535065) is an iPhone and Apple Watch app. It calculates a daily biological age from 21 biomarkers: Apple Health / HealthKit data from Apple Watch, Oura, or Garmin, plus optional lab results so conventional values you already have can sit in the same score.

Coaching runs as on-device AI, so health data stays on the phone. There is no account. Apple’s privacy nutrition label for Nuvo is Data Not Collected. Price is $4.99/month or $24.99/year after a 7-day free trial. $24.99/year is $2.08/month billed annually. Nuvo is not Android, does not operate a clinic, and does not draw blood.

Your biological age, calculated daily, on your phone, with your data.

Nuvo is not a 60-minute SoHo scan, a dermatologist’s mole map, or a 50+ biomarker same-visit panel. If the job is “sit with a clinician and leave with a radiation-free baseline of skin, heart, circulation, body composition, and blood,” that is Neko Health. If the job is “one daily biological age from 21 biomarkers, including optional labs, privately, on the phone you already carry,” that is Nuvo. Download app. For a 160+ conventional lab membership rather than a clinic scan, see Nuvo vs Function Health. For a sleep ring whose data can reach an iPhone through HealthKit, see Nuvo vs Oura. For what “biological age” means next to calendar age, see biological age vs chronological age.

Comparison table

When to choose Neko Health

Choose Neko if the job is a clinician-led baseline you cannot get from a phone. Mole mapping with a dermatologist reviewing concerning spots, an ECG, blood pressure and a small-vessel circulation check, visceral fat, grip strength, eye pressure, and 50+ blood biomarkers back in the same visit are the product. Nuvo does not photograph your skin, does not run an ECG clinic, and does not draw blood. If you are in or can travel to SoHo — and later to the other cities Neko has named — and you want that hour with a clinician, Neko is the right buy. $499 self-pay, with HSA/FSA cards accepted, is the published price of that hour.

Neko also fits if you want a human to interpret the stack before you leave. The second half of the visit is the clinician review. The medical terms are clear that this is preventive investigation, not treatment and not primary care. That is still a different job from an app that scores yesterday’s sleep.

When to choose Nuvo

Choose Nuvo if you cannot get to SoHo, or you do not want to wait for the next city on Neko’s list. The scan requires a clinic. Nuvo requires an iPhone. The score is available on the days you are not in New York.

Choose Nuvo if you want to know whether habits are working between scans. A $499 visit is a snapshot. Sleep, training, and resting heart-rate trends move on a scale of days. Nuvo recalculates a daily biological age from 21 biomarkers so those changes have somewhere to show up without booking another hour. Your biological age, calculated daily, on your phone, with your data.

Choose Nuvo if privacy and price are the constraint. $24.99/year after a 7-day trial is not a discount on a $499 clinical scan — it is a different object — and it does not require an account. Health data stays on the phone. Apple’s label for Nuvo is Data Not Collected. If you will not put a clinic chart in a patient portal, do not buy Neko. If you will not put longitudinal wearable data on an app account, Nuvo is built for that constraint.

How to use them together

Use both if you can reach a Neko clinic and you still want a daily read on the iPhone you already wear an Apple Watch with. Neko is the periodic deep baseline: skin, heart, circulation, body composition, 50+ labs, and a clinician. Nuvo is the daily loop between those visits. They do not cancel each other.

The handoff is limited, and it should stay that way. Nuvo does not connect to Neko’s clinic record, mole map, ECG tracing, or clinician note. Neko’s app can sync wearable data such as Oura or Whoop through Apple Health so the clinic has context. Nuvo reads HealthKit on the phone to compute its own 21-biomarker score. Same watch, two different uses. If a Neko blood panel, or any other draw, leaves you with ordinary lab values such as HbA1c, fasting glucose, HDL, CRP, or creatinine, those optional results can sit in Nuvo’s score. A Neko appointment does not become Nuvo’s biological age, and Nuvo does not become a dermatologist.

If the only job is the clinic hour, stop at Neko. If the only job is a daily biological age from 21 biomarkers, privately, on iPhone, stop at Nuvo. If you already paid for the scan and still want to see whether the next three months of sleep and training moved a number, add Nuvo. For a membership of 160+ conventional labs instead of a single clinic hour, see Nuvo vs Function Health. Habits that move the markers a daily score actually reads are covered in how to reduce biological age.

Biological age, stated carefully

Neko’s public US materials describe a scan and a clinician review. They do not, on the opening release, the health-scan page, or the medical terms, describe a biological age score. A trajectory you build by repeating the visit is not the same object as a number an app prints every morning. This page will not relabel Neko’s panel as one.

Nuvo’s number is a daily biological age from 21 biomarkers: wearable data already in Apple Health, plus optional labs. It is not an epigenetic clock, not a mole map, and not a substitute for the tests Neko runs in the room. The difference between a biological age and a birthday is covered in biological age vs chronological age.

Privacy

Neko is a medical clinic. To be scanned you book, pay, and hold results in the Neko Health app. The financial agreement discusses protected health information, a patient portal, and a HIPAA request about what is shared with a health plan. That is the right shape for a clinical service. It is a different shape from an on-device app.

Nuvo requires no account. The App Store privacy label is Data Not Collected. The score is computed on the phone. Data is not sent to Nuvo servers and is not sold. Architecture notes: health app privacy and on-device AI.

Pricing math without a fake discount

Neko’s US price on the 24 September 2026 opening release is $499 per scan. A second scan is another $499 at that published price. We do not invent a membership rate, a twice-a-year package, or a post-waitlist discount those pages do not print. HSA/FSA cards are accepted; insurance is not billed. Whether a commercial plan reimburses you is between you and that plan.

Nuvo is $4.99/month or $24.99/year ($2.08/month billed annually) after a 7-day free trial. No scan is included.

Those dollars buy different things. Comparing $499 once to $24.99 a year as if they were the same product is a category error. One is an hour in a clinic with a clinician, imaging, and 50+ labs. The other is a daily 21-biomarker biological age on the phone you already carry. Many people who can get to SoHo will still want to know, on a Tuesday in between, whether sleep and training moved the number. That is the Nuvo add, not a rip-and-replace.

Scale of reviews is not close, and we will not pretend it is. Nuvo’s US App Store presence is early: 4 ratings. We do not invent a rating count for the Neko Health app, we do not inflate four Nuvo ratings into social proof, and we do not publish a schema.org rating object for Nuvo.

Frequently Asked Questions

Should I pick Nuvo or Neko Health?
Pick Neko Health if you can reach a clinic and want a clinician-led, radiation-free visit of about an hour — skin imaging with dermatologist review of concerning moles, ECG and circulation, body composition including visceral fat, grip strength, eye pressure, and 50+ blood biomarkers with same-visit results — for $499 self-pay. The first US clinic is at 300 Lafayette Street in SoHo. Pick Nuvo if you want a daily biological age from 21 biomarkers on iPhone and Apple Watch, optional labs in that same score, on-device AI, no account, and $4.99/month or $24.99/year after a 7-day free trial. If you can do the scan and still want a daily number between visits, use both.

Is Neko Health a biological age app?
No. Neko Health is a clinic scan with a companion app on iOS and Android that stores results and can sync wearables such as Oura or Whoop via Apple Health. Neko’s US opening release, health-scan page, and medical terms do not publish a biological age score. Nuvo is the product that calculates a daily biological age from 21 biomarkers on the phone.

Can I use Nuvo with a Neko Health scan?
Yes. They are complementary. Neko is the periodic in-person baseline. Nuvo is the daily 21-biomarker score on HealthKit plus optional lab results you enter. Nuvo does not read Neko’s mole map, ECG, or clinician note. Ordinary lab values you already have, from Neko or anywhere else, can be included in Nuvo. You do not have to pick only one.

How much do Neko Health and Nuvo cost?
Neko’s published US price is $499 per scan, self-pay. HSA/FSA cards are accepted. Neko does not bill insurance, and reimbursement from a commercial plan is not guaranteed. Nuvo is $4.99/month or $24.99/year ($2.08/month billed annually) after a 7-day free trial. A second Neko scan is another $499 at the published per-scan price. We do not invent a bundle discount.

Does Neko Health accept insurance?
No. Neko’s US medical terms say it does not currently accept insurance. The financial responsibility agreement is a self-pay agreement: Neko will not bill commercial insurance or government programs. You can keep the itemized receipt and ask a commercial insurer yourself. Neko does not promise payment.

What if I cannot get to SoHo?
The US scan, as of the 24 September 2026 opening, is at one clinic: 300 Lafayette Street, SoHo. Neko says more New York sites, Miami, Washington, D.C., and San Francisco are planned. Until a clinic is near you, the scan is a trip. Nuvo is an App Store download and does not require a clinic visit. That is the practical reason to use Nuvo while you are on a waitlist or outside those cities.

Does Nuvo require an account?
No. Nuvo uses on-device AI and no account. Apple’s privacy label is Data Not Collected. Health data stays on the phone. Neko is a clinic: you book a visit and results live in the Neko Health app. Nuvo uses 21 biomarkers (HealthKit plus optional labs). Neko’s 50+ on-site blood biomarkers are a different assay, done in the clinic.

Is this medical advice?
No. This comparison is educational and is not medical advice. A Neko scan is interpreted by Neko’s clinicians and is not a substitute for your own physician. Nuvo’s biological age is a daily score from 21 biomarkers, not a diagnosis. Skin findings, blood results, ECG tracings, and eye-pressure screens belong with a qualified clinician.
