Nuvo vs Bevel: Daily Biological Age vs Apple Watch Health App

Pick Bevel for Apple Watch recovery, sleep, and strain, plus a weekly Biological Age on Pro. Pick Nuvo for a daily 21-biomarker biological age. Many Bevel users can stack.

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

Choose Bevel if you want an Apple Watch health app in the recovery, sleep, and strain family — daily readiness scores, nutrition logging, strength training, and, on Pro, a Biological Age that updates every Monday from fitness factors plus bloodwork. Choose Nuvo if you want a daily biological age on iPhone and Apple Watch from 21 biomarkers — HealthKit wearables plus optional conventional lab PDF — with on-device AI, no account, and $24.99/year after a 7-day trial. They are adjacent jobs, not substitutes. Bevel is the Apple Watch health coach (and a weekly age). Nuvo is the daily 21-biomarker number. Many people already using Bevel can stack Nuvo.

What each product actually sells

Bevel: an Apple Watch health coach, with a weekly Biological Age on Pro

Bevel (developer Finerpoint, Inc.; App Store seller Starlight Tech LLC) is a connected health coach for Apple Watch and Apple Health. The US App Store listing (Bevel: AI Health Coach, id 6456176249) positions it around sleep, recovery, stress, strength, nutrition, and longevity guidance. Getting started says Bevel works with Apple Health and works best when you wear an Apple Watch 24/7 (except while charging). The listing requires iOS 18.0 or later, watchOS 10.6 or later, and can run on Apple silicon Macs with macOS 15.0 or later. Recent App Store release notes also describe Garmin, Oura, and Google Health as additional data sources. The core job is still the Apple Watch health app: interpret the watch data you already have.

What the free tier actually includes, from Bevel’s membership and pricing article (edited 13 July 2026):

• Recovery, Sleep, Strain, Stress, and Energy Bank — daily scores.
• Nutrition tracking (barcode, image, recipe, text, or a 6 million+ food database on the App Store description), Strength Builder (700+ exercises), fitness tracking, health monitors (heart rate, HRV, resting heart rate, respiratory rate, blood oxygen), cycle tracking, journal, smart alarm.
• The Apple Watch app, widgets, and complications.
• AI food logging and AI workout generation stay on Free. Bevel says existing Free features stay free.

Biological Age is Pro, along with Health Records and Bevel Intelligence. Bevel’s own Biological Age basics article says the score is calculated from three groups — physiological and lifestyle factors averaged over the past four weeks, plus blood biomarkers — and updated every Monday. It is not the same object as the daily Recovery or Strain number. The physiological and fitness factors (sleep duration and consistency, steps, heart-rate zones, strength, VO₂ Max, resting heart rate, lean body mass) are the fitness-age style layer inside that weekly score. Lifestyle adds Nutrition Score, alcohol, and smoking impact. The blood piece is nine markers from Levine’s PhenoAge model, not a 21-biomarker daily composite. See physiological age factors and blood biomarkers.

Bevel is not a no-account, on-device-only biological age app. The pricing FAQ says historical logs stay in your account if you downgrade. The privacy policy describes registration (name, email, password), cloud storage for contact and user-generated logs, and optional cloud processing when Bevel Intelligence is on.

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 conventional results 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. Price is $4.99/month or $24.99/year after a 7-day trial — $24.99/year is $2.08/month billed annually. Nuvo does not replace a recovery/strain/nutrition coach, and it does not implement Bevel’s Monday Biological Age.

Nuvo is not Bevel’s Recovery Score, Sleep Score, Strain Score, Stress Score, Energy Bank, Nutrition Score, or Strength Builder. If the job is “make Apple Watch health data into daily recovery, sleep, strain, food, and lifting,” that is Bevel — and a large part of that job is free. If the job is “one daily biological age from 21 biomarkers, including optional labs, privately, on the phone you already carry,” that is Nuvo.

For a ring, see Nuvo vs Oura.

Comparison table

What each “biological age” actually measures

Bevel’s Biological Age is a weekly long-horizon score. Bevel’s basics article says it updates every Monday. Physiological factors are a four-week average, compared with optimal standards for your age and sex, using published hazard ratios, with overlap between related metrics (VO₂ Max and resting heart rate, strength and lean mass) counted once. High confidence on the wearable side means at least 20 days of data in the past month. The fitness block — VO₂ Max, resting heart rate, lean body mass — is why Bevel feels like a fitness-age and recovery product even when the label on the score says Biological Age. Daily Recovery, Sleep, and Strain are separate scores. They are the morning dashboard. They are not the Monday age.

The blood block is narrower than “all your labs.” Bevel’s blood-biomarker article says the age calculation uses nine routine markers from Levine’s PhenoAge model (Levine et al., 2018): albumin, creatinine, glucose, hs-CRP, lymphocyte percentage, MCV, RDW, ALP, and white blood cell count. Results under six months old carry full weight; older panels are discounted. You upload a blood test in Biology (or via Bevel Intelligence). Bevel’s Health Records FAQ says the score recalculates every Monday; bloodwork from the current week waits for the next Monday, while older dated results can update after upload. Bevel also lets you watch 100+ other markers in Biology, including ApoB and HbA1c. Those extra markers are not the nine inputs the blood-age article lists. Missing a high-weight marker such as RDW or MCV can cause Bevel to omit the blood-age piece rather than guess.

That blood model is the paper Bevel cites:

• Levine ME et al. An epigenetic biomarker of aging for lifespan and healthspan. Aging (Albany NY) 2018;10(4):573–591 (PMID 29676998). Bevel uses the nine clinical chemistry markers from that Phenotypic Age lineage as one component of a larger weekly score. A Nuvo daily number and Bevel’s Monday Biological Age are not interchangeable, even if both can move when sleep or a lab result changes.

Nuvo’s 21 biomarkers are wearable plus optional conventional labs — HRV, sleep, fitness, and chemistry such as HbA1c, fasting glucose, HDL, CRP, or creatinine — recalculated daily on device. Nuvo does not sell Bevel’s Recovery/Strain dashboard, does not recalculate only on Mondays, and does not claim to be Levine’s nine-marker formula.

Can they stack?

Yes — that is the honest adjacent-jobs answer for someone who already likes Bevel on Apple Watch. Keep Bevel for Recovery, Sleep, Strain, nutrition, and strength (Free covers that core). Add Nuvo if you also want a daily biological age from 21 biomarkers, including a lab PDF you already have, without an account. Nuvo does not ingest Bevel’s Recovery Score, Strain Score, Nutrition Score, or Monday Biological Age as named inputs. Both can read Apple Health. A standard lab PDF can sit in Nuvo’s 21-biomarker score; that does not turn Nuvo into Bevel’s nine-marker PhenoAge component, and Bevel’s Monday age does not become Nuvo’s daily clock.

If you only want the Apple Watch recovery and training dashboard, stop at Bevel — you may not need Pro, and you may not need Nuvo. If you only want the daily 21-biomarker age, stop at Nuvo. If you already live in Bevel and still want a private daily age number, stack them. Pro is what unlocks Bevel’s own Biological Age; Nuvo’s daily score does not require Bevel Pro.

Privacy

Bevel is an account product. The privacy policy (Finerpoint, Inc., d/b/a Bevel, last updated 27 April 2026) says the company collects contact and profile data, user-generated workouts and diet logs, and health information you permit from Apple Health or lab connections (heart rate, sleep, movement, blood oxygen, respiratory rate, height, weight, age, and blood tests). Contact data and non-biometric logs are stored with cloud hosting so they sync. Imported biometric health information is, by default, stored and processed on the device; Bevel says it does not store that biometric import in the ordinary course unless you enable Bevel Intelligence. Turning Intelligence on sends the minimum relevant health information to third-party cloud and AI providers. Reproductive health is excluded from Intelligence unless you opt in. Conversation-related biometric data may be retained up to 30 days for debugging, then deleted; conversation history itself stays until you ask for deletion. The policy says Bevel does not sell Personal Information for monetary consideration, and that some Intelligence disclosures may count as “sharing” under state privacy laws, which you can opt out of by disabling the feature. The same policy states Finerpoint is not a HIPAA covered entity or business associate, and that health information in the app is not protected health information. The US App Store privacy label, as fetched 23 September 2026, lists Identifiers under data used to track you, and lists Device ID (advertising or marketing) plus email and name (analytics) as data linked to you. Apple publishes that label from the developer. Homepage copy says Bevel never sells your data. Read the policy if the account and Intelligence path matter to you. Contact is hello@bevel.health.

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 Bevel’s cloud sync, nutrition history, and optional Intelligence coach, that is a different privacy design, and it is a fair trade for people who want those features. 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 Bevel wins

Bevel wins if the job is an Apple Watch health app: Recovery, Sleep, Strain, Stress, Energy Bank, a large food database, and Strength Builder, with an Apple Watch app and complications. Nuvo does not claim to beat Bevel at meal logging, muscular-strain strength tracking, a smart alarm, or a free forever tracking tier. If that is the product you came to buy, buy Bevel. The free plan is a real product, not a locked demo. Bevel says features that are Free today stay free.

Bevel also wins if you want its weekly Biological Age, specifically the Monday score that mixes four-week fitness and lifestyle factors with the nine PhenoAge blood markers, plus a confidence level and a change-from-last-week view. That is a long-horizon age inside a training app. It is Pro ($99.99/year or $14.99/month on the US public prices we checked). Nuvo’s daily 21-biomarker score is a different resolution: every morning, not every Monday, and not Bevel’s named factor list.

Scale is not close. Bevel’s US App Store listing had 16,314 ratings at 4.8 when we looked it up on 23 September 2026. Nuvo’s App Store presence is early: 4 ratings. That gap is real. 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. Bevel’s age moves on Mondays, from a rolling month of inputs. A strong Strain day does not, by itself, print a new biological age the next morning inside Bevel. Nuvo recalculates a daily biological age from 21 biomarkers so sleep, HRV, training, and optional labs can sit in one number without waiting for the weekly job.

Nuvo wins on price if the only thing you want is that daily age. Bevel’s Biological Age requires Pro at $14.99/month or $99.99/year. Nuvo is $4.99/month or $24.99/year ($2.08/month billed annually) after a 7-day trial, and the daily score is the product, not a Pro add-on on top of a training suite. Those are not like-for-like discounts. Bevel Pro also buys Intelligence and Health Records. If you already want that suite, the $99.99 is buying more than an age number. If you do not, you should not pay Pro prices to get a daily age Bevel does not sell.

Privacy is structural. Bevel is an account, with cloud logs and optional cloud AI. Nuvo is no account and Data Not Collected. Conventional labs in Nuvo are optional PDFs in the same 21-biomarker score, including markers such as HbA1c and HDL that Bevel can chart in Biology but does not list among the nine PhenoAge age inputs. Those panels do not become Bevel’s Monday score, and Bevel’s nine-marker blood age does not become Nuvo’s daily clock.

Who wins for which user

Buy Bevel if you want Apple Watch recovery, sleep, strain, nutrition, and strength, and you are fine with an account. Add Pro if you also want Bevel Intelligence, Health Records, and the Monday Biological Age. Buy Nuvo if you want a daily 21-biomarker biological age on iPhone and Apple Watch, privately, at $24.99/year. Buy both if you already use Bevel for the daily training dashboard and still want a private daily age from HealthKit plus any conventional lab PDF you have. They do not cancel each other. One is an Apple Watch health app with a weekly age on Pro. The other is a daily age readout.

If the only job is “recovery and strain on the watch I already wear,” stop at Bevel. If the only job is “daily biological age from 21 biomarkers, privately, on iPhone,” stop at Nuvo. Download app.

Pricing math without invented discounts

Bevel US public prices we verified on 23 September 2026, from the membership article and the App Store in-app purchases: Free at $0 for the tracking experience listed above. Pro monthly $14.99. Pro annual $99.99 (the help article prints about $8.33/month). A 12-month commitment billed monthly at $10.99 is not currently available for US and Singapore users, so we do not quote it as the US price. Optional Intelligence credit packs on the US listing included 350 credits at $4.99, 750 at $9.99, 1,550 at $19.99, and 4,200 at $49.99. Family Sharing is included on Pro. Trial availability and length may vary; Bevel tells you to check the in-app screen, so we will not invent a trial length. Prices outside the US follow Apple’s regional tiers. Existing subscribers may be grandfathered; the help article describes that separately from the current sticker price.

Nuvo: $4.99/month or $24.99/year ($2.08/month billed annually) after a 7-day trial. No Bevel Pro subscription is required to get Nuvo’s daily score.

Those dollars buy different things. Say so. Comparing $99.99/year Bevel Pro to $24.99/year Nuvo as if they bought the same object is a category error. Bevel Pro is Intelligence, Health Records, and a Monday Biological Age on top of a free recovery app. Nuvo is a daily 21-biomarker biological age. Many high-intent Apple Watch owners already use Bevel. The remaining question is whether they also want that daily number, privately. That is the Nuvo add, not a rip-and-replace.

Frequently Asked Questions

Should I pick Nuvo or Bevel?
Pick Bevel if you want an Apple Watch health app for recovery, sleep, strain, stress, nutrition, and strength. Core tracking is free. Pro ($14.99/month or $99.99/year on the US prices we checked 23 September 2026) adds Bevel Intelligence, Health Records, and a Biological Age that updates every Monday. Pick Nuvo if you want a daily biological age from 21 biomarkers on iPhone and Apple Watch, optional conventional lab PDF in that same score, on-device AI, no account, and $24.99/year after a 7-day trial. If you already use Bevel, you can stack: Bevel for the daily health dashboard, Nuvo for the daily 21-biomarker age.

Is Bevel a daily biological age app?
No. Bevel is an Apple Watch health and recovery app. Its daily numbers are Recovery, Sleep, Strain, Stress, and Energy Bank. Biological Age is a separate Pro feature, recalculated every Monday from about four weeks of physiological, lifestyle, and blood data. That Monday score includes fitness factors such as VO₂ Max, resting heart rate, and lean body mass, plus nine PhenoAge blood markers. It is not a new biological age every morning.

Can I use Nuvo with Bevel?
Yes. They are complementary. Bevel (including the free tier) is the Apple Watch recovery, sleep, strain, nutrition, and strength coach. Nuvo is the daily 21-biomarker readout on HealthKit plus optional lab PDFs. Nuvo does not ingest Bevel’s Recovery, Strain, or Monday Biological Age as named inputs. You do not have to cancel Bevel to use Nuvo, and you do not need Bevel Pro for Nuvo’s daily score.

Does Bevel’s Biological Age update every day?
Not on Bevel’s public docs. The basics article and the Health Records FAQ both say Biological Age is recalculated every Monday, using a rolling window of recent data (physiological factors averaged across the past four weeks). Bloodwork taken this week generally waits for the next Monday. Daily Recovery and Strain can still change every day. Those are different scores.

How much do Bevel and Nuvo cost?
Bevel’s core tracking is free. Pro is $14.99/month or $99.99/year (about $8.33/month) on the US help article and App Store listing we checked 23 September 2026. Biological Age is on Pro, not on Free. A $10.99/month annual commitment is listed but not available in the US. Nuvo is $4.99/month or $24.99/year ($2.08/month billed annually) after a 7-day trial. Bevel’s trial length varies; check the app. We do not invent one.

Does Bevel require an account?
Yes. Bevel’s pricing FAQ refers to data staying in your account, and the privacy policy describes registration with name, email, and password, plus cloud storage for profile and user-generated logs. Imported biometric health data is on-device by default until you turn on Bevel Intelligence. Nuvo uses on-device private AI and no account. Apple’s privacy label for Nuvo is Data Not Collected. Nuvo uses 21 longevity biomarkers (HealthKit plus optional labs such as HbA1c, fasting glucose, HDL, CRP, creatinine). Bevel’s nine-marker PhenoAge blood component is a different assay inside a weekly score.

Is Bevel’s Biological Age the same as Nuvo’s 21-biomarker score?
No. Bevel’s Monday score mixes four-week fitness and lifestyle factors with nine blood markers from Levine’s 2018 Phenotypic Age model, and it is a Pro feature. Nuvo’s score is a daily composite of 21 biomarkers, wearable plus optional labs, calculated on device. Sharing an Apple Watch does not make the two numbers the same. Bevel is not a medical device, and neither score is a diagnosis.

Is this medical advice?
No. This comparison is educational and is not medical advice. Bevel’s App Store listing says Bevel is not a medical device and is not intended to diagnose, treat, cure, monitor, or prevent disease. Bevel’s Biological Age article says the score is an educational tool grounded in population research, not a diagnosis. Nuvo’s daily biological age is also not a diagnosis. Wearable scores, lab results, and training plans should be reviewed with a qualified professional.
