SuperAge vs Nuvo: Which Biological Age App for Apple Watch?

Pick SuperAge for a free wearable bio-age plus $49.99/yr SuperTrainer. Pick Nuvo for a daily 21-biomarker score with optional labs, no account, $24.99/yr.

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

Choose SuperAge if you want a free first biological-age calculation, SuperTrainer workout and recovery coaching, and Premium at $49.99/year on Apple Watch. Choose Nuvo if you want one daily biological age from 21 biomarkers — HealthKit wearables plus optional lab PDF — with on-device AI, no account, and $24.99/year after a 7-day trial. Both are iPhone biological-age apps. They are not the same product: SuperAge is training-forward with named blood clocks as an add-on; Nuvo is a daily 21-biomarker score that can include labs you already paid for.

What each app actually sells

SuperAge: wearable bio-age plus SuperTrainer

SuperAge: Biological Age App (App Store id 6751951815) is an iPhone and Apple Watch app. SuperAge’s site markets a score from sleep, HRV, activity, and “50+ biomarkers” across domains such as workout, nutrition, sleep, body energy, and recovery — quote that as marketing copy, not a published lab panel. The US App Store listing is explicit on the commercial model: the initial biological age calculation is free; Premium unlocks advanced analyses, detailed charts, SuperTrainer, and long-term insights. In-app purchases on that listing are Annual Premium $49.99 or Monthly Subscription $4.99.

SuperAge works with Apple Health and Apple Watch. The listing also claims Oura, Whoop, and smart scales via Health. Privacy copy on both the listing and superage.app is on-device processing with Apple Intelligence and no required cloud sync.

Blood labs are the one place SuperAge’s own pages disagree with each other. Their SuperAge vs Humanity comparison still lists “Blood test uploads: No” and describes SuperAge as wearable-only. That page is stale. The current App Store listing includes blood-test PDF upload, and SuperAge’s own PhenoAge / KDM write-up describes SuperAge 3.2 scanning a lab PDF to compute those published clocks. We are not going to pretend the vs-Humanity table is current. SuperAge is training-forward first; labs, when used, feed named clocks (PhenoAge/KDM), not a fused daily 21-biomarker score.

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 PDF upload so results you already paid for sit in the same score.

Coaching runs as on-device private AI (Nuvo Intelligence). 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 trial — $24.99/year is $2.08/month billed annually.

Nuvo is not SuperTrainer. It does not sell a free forever biological-age number, and it does not compute PhenoAge or KDM as named clocks. If the job is “train off a wearable age and a Body Energy battery,” that is SuperAge. If the job is “one daily number from 21 biomarkers, including optional labs, privately, on the watch you already own,” that is Nuvo. For the wider field, see our 2026 biological age app comparison. For a lab-membership contrast rather than another watch app, see Nuvo vs Function Health. For a wearable-only aging-rate contrast, see Nuvo vs Humanity.

Comparison table

Where SuperAge wins

SuperAge wins on free entry. The App Store listing is clear: the first biological age calculation is free. Nuvo is a 7-day trial, then $4.99/month or $24.99/year. If you only want to see a number once, SuperAge is the cheaper experiment.

SuperAge also wins if you want a training-and-recovery cockpit. SuperTrainer, workout zone analysis, Body Energy, and readiness-adjusted daily goals are the product SuperAge is built to sell. Nuvo’s coach is biomarker-and-intervention-oriented, not a session planner.

On ratings volume, SuperAge is ahead. About 4.8 from 88 US ratings is a real corpus. Nuvo’s App Store presence is early: 4 ratings. We will not dress that up.

If the specific job is published PhenoAge or KDM from a lab PDF, SuperAge 3.2 is built for that named-clock workflow. Nuvo does not compute those clocks. Nuvo puts optional labs into one daily 21-biomarker score instead.

Device breadth on SuperAge’s listing also includes Whoop and smart scales via Apple Health. Nuvo’s HealthKit path is Apple Watch, Oura, or Garmin. If Whoop is your strap, SuperAge’s claim is the closer match — still via Health, not a native Whoop SDK we can verify from public pages.

Where Nuvo wins

Nuvo wins on annual price if you are already going to subscribe. SuperAge Premium is $49.99/year. Nuvo is $24.99/year after the trial — half the annual IAP, or $2.08/month billed annually. Month-to-month is the same $4.99 on both App Store listings.

Nuvo wins on one daily score that can include labs. SuperAge’s wearable age and PhenoAge/KDM are different clocks. Nuvo’s 21 biomarkers — wearables plus optional lab PDF — land in the same daily biological age. That is the differentiation even after SuperAge added PDF upload. We are not going to claim SuperAge “cannot do labs.” Their vs-Humanity post said that; their App Store listing no longer does.

Privacy is a structural difference, not a slogan. SuperAge advertises on-device Apple Intelligence. Nuvo requires no account and uses the Apple privacy label Data Not Collected. If you will not create a health account and you want that nutrition-label line, Nuvo is the one built for that constraint.

Nuvo also wins if you already pay for blood work and want those results in the daily loop — the same job as uploading a Function (or any clinician) PDF. SuperAge’s PDF path is a PhenoAge/KDM calculator. Nuvo’s PDF path is an input to the 21-biomarker score. Different math, same file type.

Can you use both?

Yes. SuperAge for SuperTrainer and a free wearable checkpoint; Nuvo for the daily 21-biomarker number with optional labs. They do not cancel each other. Most people will not pay $49.99 plus $24.99 for two overlapping scores. If you pick one: SuperAge for training-forward free-to-start; Nuvo for daily fused score, no account, lower annual.

Pricing math without invented discounts

SuperAge: free first calculation; Premium $49.99/year or $4.99/month on the US App Store listing we checked. SuperAge’s site shows a 4.6 App Store badge; the US lookup we used reported ~4.8 from 88 ratings. We cite the lookup for the US corpus and do not invent a worldwide count.

Nuvo: $4.99/month or $24.99/year ($2.08/month billed annually) after a 7-day trial. No lab draw is bundled.

Comparing $49.99 to $24.99 is fair only as subscription math. SuperAge’s free tier is a real product difference Nuvo does not match. Nuvo’s no-account / Data Not Collected architecture is a real product difference SuperAge’s public pages do not claim in those words.

Frequently Asked Questions

Should I pick SuperAge or Nuvo?
Pick SuperAge if you want a free first biological age, SuperTrainer training/recovery coaching, and Premium at $49.99/year. Pick Nuvo if you want a daily biological age from 21 biomarkers on iPhone and Apple Watch, optional lab PDF in that same score, on-device AI, no account, and $24.99/year after a 7-day trial.

Does SuperAge upload blood tests?
Yes on current SuperAge public product copy. The App Store listing describes blood-test PDF upload, and SuperAge 3.2 documents PhenoAge and KDM from a scanned PDF. SuperAge’s own vs-Humanity article still says “Blood test uploads: No.” Cite the listing and the 3.2 post for the shipping product; treat the vs-Humanity table as outdated. Nuvo also accepts an optional lab PDF, into a 21-biomarker daily score rather than those named clocks.

How much do SuperAge and Nuvo cost?
SuperAge Premium is $49.99/year or $4.99/month on the US App Store; the first biological age calculation is free. Nuvo is $4.99/month or $24.99/year ($2.08/month billed annually) after a 7-day trial.

Does Nuvo require an account?
No. Nuvo uses on-device private AI and no account. Apple’s privacy label is Data Not Collected. SuperAge advertises on-device Apple Intelligence and no required cloud sync on its site and listing.

How many biomarkers does Nuvo use?
21 longevity biomarkers. They combine HealthKit wearable inputs with optional labs such as HbA1c, fasting glucose, HDL, CRP, creatinine, and more. SuperAge’s homepage markets “50+ biomarkers” as multi-domain wearable scoring — not a 50-marker blood panel.

Which app has better App Store ratings?
SuperAge’s US listing has a much larger base: about 4.8 from 88 ratings on the lookup we checked. Nuvo is 5.0 from 4 US ratings. That Nuvo average is real and too thin to treat as social proof. We do not publish a schema.org rating object for Nuvo.
