The short version: this is a free educational tool, not medical care, and its estimates are not guaranteed accurate. Use it with a qualified healthcare professional, not instead of one.
Last updated 2026-10-17.
By using this site or calculator, you agree to these terms. If you do not agree, do not use the service. The dashboard is a free educational and personal tracking tool, with no account required.
It is intended for adults aged 18 and older. Do not use its estimates to assess a child, pregnancy, an acute illness or a medical emergency.
Biological ages, Longevity Scores, reference ranges and AI responses are educational estimates, not a diagnosis, treatment plan or prediction of lifespan. The scoring model is not clinically validated and no individual accuracy or health outcome is guaranteed.
Using the dashboard, uploading a report or chatting with the AI coach does not establish a clinician-patient relationship. A separately booked clinical consultation is a separate service.
Do not start, stop or change medication, supplements, training or treatment based on these outputs alone. Discuss results with a qualified healthcare professional. In an emergency, contact local emergency services rather than this tool. See the medical disclaimer and methodology for further limitations.
You are responsible for entering accurate values and units and for checking any values extracted from an uploaded report against the original before relying on a score. Missing or incorrect inputs can materially change results.
Upload only documents you are entitled to share. Avoid including unnecessary identifying information, and do not submit someone else's health information without their permission.
Lab report upload and the AI coach send data to Anthropic through our Cloudflare Worker. AI can misread documents and produce incorrect or incomplete responses. These features are optional; manual scoring works without them. Read the privacy policy before sending information.
Assessments are saved in your browser, not in a recoverable account on our servers. Clearing browser data or losing access to your device can permanently erase them. Export any records you want to keep and protect access to shared devices.
The service is provided as available. Features, ranges and scoring rules may change, and access may be interrupted or discontinued. A software update can change an estimate even when your inputs have not changed.
Do not interfere with the service, attempt unauthorised access, bypass rate limits or use the upload and AI features for unlawful purposes.
You retain your rights in the information you supply. Nothing in these terms transfers ownership of your health data. Site content and software remain subject to applicable intellectual property rights; access to the dashboard does not grant permission to resell or misrepresent its content as your own clinical advice.
To the extent permitted by applicable law, the dashboard is provided without warranties of accuracy, fitness for a particular purpose or uninterrupted availability. Beso Wellness and Beauty is not responsible for losses arising from reliance on educational estimates or AI responses instead of professional care.
Nothing in these terms excludes liability or limits consumer rights that cannot lawfully be excluded or limited. These terms do not replace any separate agreement for clinical services.
We will publish changes on this page with an updated date. Review the current terms when you use the service; if you do not accept revised terms, stop using it.

Calculate your Longevity Score free →Choose a question. Answers come from this site, and nothing you open is sent anywhere.
Chronological age counts birthdays. Biological age estimates how old your body appears to be functioning, based on measurable biomarkers. Two people born the same year can differ by a decade or more in vascular stiffness, insulin signalling or cardiorespiratory fitness. Biological age makes that gap explicit — and unlike your birthday, it can move in either direction.
Each biomarker you enter is scored against longevity-optimised reference ranges and grouped into one of eight dials. Every dial produces its own biological age, and those are combined using fixed weights into a single composite, then expressed as a Longevity Score from 0 to 100. The weighting reflects how strongly each system predicts healthspan: structural and vascular carry the most, hormonal the least.
No. The short form contains a subset of scoring inputs plus context-only fields, and you can leave any of them blank. It is not a recommendation to obtain tests. Missing values are excluded from the calculation — never treated as zero or as 'normal'. A dial with no scored data is dropped entirely and the remaining weights renormalise.
Some inputs can be measured without bloodwork. Blood pressure needs a home cuff and waist-to-height needs a tape measure. Wearable estimates vary; the floor-based sitting-rising test carries a fall risk and should only be attempted if safe.
Both terms describe what this tool does, and which one fits depends on what you are asking. "Anti-aging" is the term most people search, and loosely means anything aimed at slowing or reversing age-related decline — this tool fits that description if you score your dials and act on what you find. "Healthspan calculator" is the more precise term: healthspan is the number of years lived without serious chronic disease or disability, and that cannot be measured directly, so this tool scores eight systems that each function as an early-warning proxy for it. Either way, the method is the same: real biomarkers, published thresholds, no vanity-metric framing.
Several popular tools ask only about habits — exercise days, sleep hours, smoking, diet quality — and return a single precise-looking age. We looked at the research behind that approach and chose not to build it. Published studies do show real, individually-measured links between specific habits and epigenetic age acceleration, but those effect sizes come from different study populations, different DNA-methylation clocks and different measurement units. Adding them together into one number is not something the underlying research actually supports — it produces a precise-looking result built on an imprecise method. Our dials use direct physiological measurements instead: a real blood pressure reading, a real VO₂ max, a real ApoB value. Several dials score from home-measurable data alone with no quiz-guessing involved — see what you can measure without a blood test, above.
Standard reference ranges describe what is common in a general population, which now includes a great deal of metabolic dysfunction. They are tuned to flag disease, not to identify what is optimal for a long healthspan. A fasting insulin of 20 µIU/mL sits inside most labs' normal range and is strongly associated with insulin resistance. This tool uses longevity-optimised thresholds instead, so a flag here means room for optimisation — not a diagnosis.
For understanding a single result, do — a frontier chat model is genuinely good at that, often clearer than most medical sites, and it handles markers no fixed tool covers. The limitation is different from the one most people assume. A language model produces a plausible response rather than a computed one, so the same panel can score differently on different days. That is fine when exploring an idea and disqualifying when measuring change, because you cannot tell how much of a difference is you and how much is the method. Use both: a chat model to understand, a fixed instrument to track.
Biomarker values, assessment history and visit-preparation drafts are stored in your browser. The visit draft is separate from assessment exports and share links; copying or printing it can leave a copy outside the browser. There are no user accounts or third-party tracking. We keep anonymous usage totals on our own server, such as how many people reached a results screen on a given day; browsers sending Do Not Track or Global Privacy Control are not counted. Optional lab-report upload and AI coach features send data to Anthropic. Optional retest reminders send an email address, date and reminder label to our service and email provider. See our privacy policy for details.
No. It is an educational and personal-tracking tool. The estimates are not clinically validated and must not replace evaluation by a qualified healthcare professional. If a result concerns you — particularly kidney markers, blood pressure or ApoB — take it to a doctor rather than acting on it alone.
