Nuvo vs Gyroscope: Daily Biological Age or Health Score Coaching?

Pick Gyroscope for a Health Score, Food XRAY, and a 24/7 coach ($39/mo). Pick Nuvo for a daily 21-biomarker biological age on iPhone, on-device, no account.

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

Use Gyroscope if you want a lifestyle Health Score, photo food tracking, and a 24/7 AI coach that pulls Apple Watch, Oura, Garmin, and Whoop into one account. Use Nuvo if you want a daily biological age on iPhone and Apple Watch from 21 biomarkers — HealthKit plus optional lab results — computed on the phone, with no account. They overlap on the same wearable owner. They do not sell the same number. Gyroscope One is $39/month on Gyroscope’s 2026 lineup page; Nuvo is $4.99/month or $24.99/year after a 7-day trial.

Gyroscope details below are taken from Gyroscope’s public One page, homepage, Health Score page, V10 and Max announcements, V11 notes, at-home blood page, membership support page, privacy policy, a coach-specific Max page, and the US App Store listing (id 1104085053, Gyroscope, seller Gyroscope Innovations, Inc.), checked 7 October 2026. The Canada listing is cited only where it prints a billing-period label the US list does not. Prices are the figures those pages printed that day; checkout, region, and promo can differ. This page is educational and is not medical advice. Gyroscope’s Health Score and biological-age estimate are not a clinical assay, and Nuvo’s daily score is not a substitute for a clinician.

What each product actually sells

Gyroscope: Health Score, Food XRAY, and a cloud coach

Gyroscope (Gyroscope Innovations, Inc.) is an iPhone health and lifestyle tracker. The US listing is Gyroscope (id 1104085053), free to download, with in-app purchases. The public job on the Gyroscope One page (checked 7 October 2026) is one place to track the body, see insights, and work with a personal coach. The signature number is a Health Score, not Nuvo’s daily 21-biomarker biological age.

What those pages actually sell:

• Health Score — One calls it “one score that unifies all your metrics and devices.” The homepage calls it “the most important number in your life, refreshed weekly from your biometrics,” with grades, early warnings, blood and glucose monitoring, and an “estimated lifespan” line (“your habits, in years”). The Health Score feature page also describes a realtime display powered by biometrics and tracking. We cite both wordings. We do not collapse “weekly” and “realtime” into one refresh rate Gyroscope did not define.
• Personal coach — One: “24/7 guidance based on your exact biometrics.” The V11 announcement says the coach works “to keep you healthy 24/7,” including chat, background messages, custom meditations, and workouts.
• Food XRAY — photo food tracking. One: “detailed macros, micros and grades for every meal.” The homepage says Food XRAY tracks macros, calories, and micronutrients from a photo. The US App Store description calls the camera the way you log food and drink.
• Wearable sync — One lists Apple Watch, Oura, Garmin, Whoop, a wifi scale, a glucose monitor, and “thousands of other apps and devices.” The homepage repeats Apple Watch, Oura, Garmin, and Whoop, plus scale, blood pressure, glucose (Stelo or Dexcom), and a Mac desktop app for computer time.
• Bodyfat protocol, custom workouts, custom meditations — listed on the One page. The homepage leads with goals such as lose bodyfat, get stronger, and sleep better.
• Blood — One says “50% off Gyroscope blood tests, or import from any other provider.” The at-home blood page lists a one-time panel at $399 (shipping both ways; United States and Canada, not New York) and says a member price applies at checkout. That page does not print the discounted dollar amount. The Max page says “75% off blood tests.” We do not invent the checkout price those percentages would imply.

Gyroscope also describes a biological age estimate. V11 says biological age and speed of aging are estimates from your own data — sleep, nutrition, caffeine, fitness, resting heart rate, blood work, and DNA — and that they “update automatically every few weeks” as you add blood levels, track biometrics, log meals, or have a significant health change. The blood page says the $399 panel unlocks “a detailed biological age.” That is a periodic estimate inside a coaching app. It is not a daily on-device score from 21 biomarkers, and it is not the Health Score.

The V10 lineup note (checked 7 October 2026) splits 2026 plans into three:

• G1 / Gyroscope One — “powerful AI and food tracking for $39/month.” It includes what previously required Ultra or Food XRAY, including food tracking and glucose monitoring, plus guided workouts and realtime coaching.
• Ultra — for people already on it. V10 says current Ultra members keep the plan, with higher daily tokens and fewer limits. The US App Store in-app list includes Gyroscope Ultra $149.00. That list does not print “per month” or “per year” next to $149. We do not assign a period the US list does not print.
• Max — the Max announcement says performance-based pricing from $3–8 a day, depending on AI or human coaching, optional at-home blood tests, and how consistently you hit targets, with daily cashback (default $2 a day, “about $60 a month” if you stay consistent). A coach-specific page, Max with Jolene, headlines “$249/month, billed monthly” with a referral credit, and its FAQ says “Max is $229 a month, with $5 back every day you check in.” Those are different sentences on different pages. We do not merge them into one list price.

The US App Store in-app list on 7 October 2026 also shows Gyroscope One at $39.00, $299.00, $29.99, and $9.00, plus Gyroscope Pro $149.99 and Gyroscope Pro (Legacy) $99.00. The US pairs do not label $299 as annual. The Canada listing does label a SKU “Gyroscope One (Annual)” at $299.00 in that store’s displayed prices. The US description says Gyroscope One “costs just about $1 a day” and that monthly subscriptions renew monthly. Cite the listing at purchase. Legacy SKUs are on the list; V10 is the page that names the current public plan.

An account is required. The US listing: “Gyroscope requires an account to sync and view your data,” with dashboards in the app and on the website, so data survives a reinstall. The privacy policy says the service processes and stores information “much of which occurs on our servers,” and that HealthKit sync “will upload the data from your phone to our servers.” Gyroscope says it does not sell that data. It is still a cloud account, not on-device-only.

iTunes lookup on 7 October 2026: 4.84 from 50 US ratings. The US App Store page displays 4.8 out of 5 from 50 ratings. Gyroscope’s homepage and One page also publish the company’s own member figures (47.2% better sleep, 69.2% lost bodyfat, 86.8% eating better). Those are Gyroscope’s claims, not an independent trial we re-ran. We do not publish a schema.org rating object on this page.

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 labs you already paid for (HbA1c, fasting glucose, HDL, CRP, creatinine, and more) 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. Health data stays on the phone, is not sent to Nuvo servers, and is not sold. 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 Android, does not log meals from a photo, and does not replace Food XRAY, a bodyfat protocol, or a 24/7 cloud coach.

Nuvo is not Gyroscope’s Health Score. 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 the wider field, see our 2026 biological age app comparison. For another Apple Watch training app, see Nuvo vs Athlytic.

Comparison table

What each score actually measures

People comparing these two usually want “one number.” Gyroscope’s public headline number is the Health Score. The homepage ties it to weekly biometrics, a report card, early warnings, and an estimated lifespan from habits. The feature page describes a realtime view of the same idea. V11’s biological age is a separate estimate that moves every few weeks when blood, meals, or biometrics change. A weekly Health Score, a few-week aging estimate, and a morning biological age are three different clocks.

Nuvo’s 21 biomarkers are wearable plus optional conventional labs — HRV, sleep, fitness, and chemistry such as HbA1c or CRP — recalculated daily on device. A Gyroscope Health Score and a Nuvo biological age on the same calendar day are not interchangeable. Logging a meal in Food XRAY does not, by itself, move Nuvo’s score. A Nuvo lab PDF does not become Gyroscope’s V11 aging report.

Nuvo does not implement Gyroscope’s Health Score, Food XRAY grade, or V11 biological-age formula as named clocks. Gyroscope does not implement Nuvo’s 21-biomarker daily biological age.

Can they stack?

Yes — if you accept two architectures. Use Gyroscope for photo food logging, the Health Score, bodyfat coaching, and a cloud dashboard across Apple Watch, Oura, Garmin, or Whoop. Use Nuvo for the daily 21-biomarker trend on HealthKit plus any conventional lab PDF you already have. Gyroscope’s privacy policy says a connected service is one-way: Gyroscope can read that source, and it does not send your Gyroscope data back. Nuvo does not ingest the Health Score or the V11 aging report as named inputs. A standard lab PDF can sit in Nuvo’s score. It does not become Gyroscope’s $399 panel.

If you only want food tracking and a lifestyle coach, stop at Gyroscope. If you only want the daily biological age, privately, stop at Nuvo. If you already pay for Gyroscope One and still want a daily age number that never leaves the phone, stack them. You will have an account at Gyroscope and no account at Nuvo.

Privacy

This is the sharpest difference. Gyroscope’s privacy policy is explicit that the product exists to process and store your information, much of it on Gyroscope servers, including a HealthKit upload. The US listing requires an account to sync and view data, and says data is not sold. The App Store privacy label Apple prints for Gyroscope includes data linked to you (health and fitness, purchases, location, contact info, user content, identifiers, sensitive info). That is a normal design for a web dashboard that has to survive a new iPhone. It is not Nuvo’s design.

Nuvo requires no account and uses the Apple privacy label Data Not Collected. Coaching is on-device. Data stays on the phone and is not sold. If you want a website dashboard and unlimited cloud history, Gyroscope is built for that. If you will not put longitudinal wearable and lab data on an app account, Nuvo is the one built for that constraint. Architecture notes: health app privacy and on-device AI.

Where Gyroscope wins

Gyroscope wins if the job is food, weight, and a lifestyle coach in one cloud app. Food XRAY, the bodyfat protocol, custom workouts and meditations, a 24/7 coach, and a Health Score over many devices are the product. Nuvo does not claim to beat Gyroscope at photo meal logging, Whoop sync, a web dashboard, or a 50-rating App Store history. If that is the product you came to buy, buy Gyroscope.

Gyroscope also wins if you want an at-home blood kit inside the same account. The public panel is $399 before any member discount the checkout page did not print for us. Nuvo can read a lab PDF you already have. It does not mail a card.

Review volume is not close. iTunes lookup on 7 October 2026: 4.84 from 50 US ratings. Nuvo’s App Store presence is early: 4 ratings. We are not going to inflate four ratings into social proof, and we do not publish a schema.org rating object for Nuvo.

Where Nuvo wins

Nuvo wins on the daily biological-age job. Gyroscope’s headline score is a Health Score, refreshed on the cadence its pages describe (weekly on the homepage; realtime on the feature page). Its biological-age estimate updates every few weeks. Nuvo recalculates a daily biological age from 21 biomarkers so sleep, HRV, training, and optional labs can sit in one number without a Gyroscope account.

Nuvo wins on where the data lives. Gyroscope uploads HealthKit to its servers. Nuvo keeps the score on the phone, with no account and Data Not Collected.

Nuvo wins on price if you already own an iPhone (and often an Apple Watch) and you do not want the food coach. $24.99/year versus $39/month for G1 is a category difference, not a coupon. Max at $3–8 a day is a different product again. If you want Food XRAY, the dollars are not comparable — you are buying a meal logger Nuvo does not sell.

Who wins for which user

Buy Gyroscope if you want photo food tracking, a Health Score, wearable sync including Whoop, and a 24/7 coach, and you will create an account. Buy Nuvo if you want a daily 21-biomarker biological age on iPhone and Apple Watch, privately, at $24.99/year, with optional labs. Buy both if you already pay for Gyroscope and still want a daily age number that stays on the phone. They do not cancel each other; one is a cloud lifestyle coach, the other is a daily age readout.

If the only job is “Health Score, Food XRAY, and a coach,” stop at Gyroscope. If the only job is “daily biological age from 21 biomarkers, privately, on iPhone,” stop at Nuvo. Download app.

Habits that actually move aging markers — sleep, aerobic fitness, glucose, inflammation — are covered in How to reduce biological age. This page is only about which product to buy for which job.

Pricing math without invented discounts

Gyroscope prices we could verify on 7 October 2026: G1 $39/month on the V10 announcement. US App Store in-app purchases on Gyroscope: Gyroscope One $39.00, $299.00, $29.99, and $9.00; Gyroscope Ultra $149.00; Gyroscope Pro $149.99; Gyroscope Pro (Legacy) $99.00. The US list does not print a billing period beside $299. Canada’s listing labels “Gyroscope One (Annual)” at $299.00. Max: $3–8 a day on the Max announcement, with cashback (default $2/day). The Jolene Max FAQ says $229 a month with $5 back per check-in day; that page’s headline is $249/month with a referral credit. At-home blood: $399 one-time on the blood page. Membership support describes a 30-day website refund for a first subscription if you open the app at least 5 days in a row; it says App Store purchases are refunded by Apple. We did not find a printed free-trial length for Gyroscope One on the US billing blurb (it says a remaining trial is forfeit if you cancel). Tax, region, and legacy SKUs can differ — cite checkout.

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

Those dollars buy different things. Say so. Comparing $39/month Gyroscope One to $24.99/year Nuvo as if they bought the same object is a category error. Many people who already pay for a premium health app still want a daily biological age that never leaves the phone. That is the Nuvo add, not a rip-and-replace of Food XRAY.

Frequently Asked Questions

Should I pick Nuvo or Gyroscope?
Pick Gyroscope if you want a Health Score, Food XRAY photo food tracking, sync from Apple Watch, Oura, Garmin, or Whoop, and a 24/7 AI coach, and you will create an account. G1 is $39/month on Gyroscope’s V10 page. Pick Nuvo if you want a daily biological age from 21 biomarkers on iPhone and Apple Watch, optional lab results in that same score, on-device AI, no account, and $24.99/year after a 7-day trial. If you already use Gyroscope, you can stack: Gyroscope for the lifestyle coach, Nuvo for the daily 21-biomarker trend.

Is Gyroscope a biological age app?
Not in Nuvo’s sense. Gyroscope is a coaching, food, and lifestyle tracker whose headline number is a Health Score. V11 also adds a biological age and speed-of-aging estimate that updates every few weeks from sleep, meals, fitness, blood work, and DNA. That estimate is not a daily 21-biomarker score computed on the phone.

Does Gyroscope have a daily biological age?
Not on the pages we checked. The homepage describes the Health Score as refreshed weekly from biometrics (the feature page also says realtime). V11 says the biological-age estimate updates automatically every few weeks. Nuvo’s biological age is recalculated daily.

Can I use Nuvo with Gyroscope?
Yes. They are complementary if you want both jobs. Gyroscope is the cloud coach, food log, and Health Score. Nuvo is the daily 21-biomarker readout on HealthKit plus optional lab PDFs. Nuvo does not ingest Gyroscope’s Health Score as a named input. You do not have to pick only one product. Gyroscope still requires its own account.

How much do Gyroscope and Nuvo cost?
Gyroscope One / G1 is $39/month on the V10 announcement we checked 7 October 2026. The US App Store also lists a Gyroscope One in-app purchase at $299.00 without printing “annual” on that row; the Canada listing labels Gyroscope One (Annual) at $299.00. Max is described as $3–8 a day on the Max announcement, with daily cashback. Nuvo is $4.99/month or $24.99/year ($2.08/month billed annually) after a 7-day trial.

Does Gyroscope track food?
Yes. Food XRAY logs meals from a photo and returns macros, micros, and a grade. V10 includes that food tracking in G1. Nuvo does not offer photo food tracking.

Does Nuvo require an account?
No. Nuvo uses on-device private AI and no account. Apple’s privacy label is Data Not Collected; data stays on the phone. Gyroscope requires an account to sync and view data, and its privacy policy says HealthKit data is uploaded to Gyroscope servers. Nuvo uses 21 longevity biomarkers (HealthKit plus optional labs). Gyroscope’s Health Score is a different number.

Is this medical advice?
No. This comparison is educational and is not medical advice. Neither Gyroscope nor Nuvo replaces care, diagnosis, or treatment from a licensed clinician. Health Scores, biological-age estimates, wearable data, and lab results should be reviewed with a qualified professional.
