Your biological age — or cellular age — is an estimate of how your body is aging compared with the years you have lived. This free Cellular Age Check calculates it from your daily habits in about two minutes, with an optional validated PhenoAge from a standard blood test. Built for women in midlife, private by design, and educational — not a medical test.
A Cellular Age Check estimates your biological age — how your body is aging compared with the years you have lived. This free version calculates it from your daily habits in about two minutes, with an optional validated PhenoAge from a standard blood test. It is educational, private, and built for women in midlife.
Take the assessment on this page: it starts from your real age and adjusts up or down based on habits linked to healthy aging across seven pillars — sleep, movement, nutrition, stress, metabolic health, sun and connection. It is free, needs no account, and your answers never leave your device.
Yes. This check is designed for women roughly 40–65, with questions and education focused on cellular wellness in midlife — the years when factors like NAD+ decline become more relevant. It is an educational estimate, not a medical test.
No. The lifestyle assessment needs only your habits. If you have recent bloodwork, you can add nine routine markers in optional Lab Mode for a research-grade PhenoAge — but it is entirely optional.
Lifestyle-based calculators like this are educational estimates, not validated medical tests — useful for understanding which habits influence aging, not for diagnosis. For a research-grade number, Lab Mode uses the published PhenoAge formula; for the most precise measure, ask a clinician about epigenetic testing.
Completely. Every answer is processed in your browser and never stored or sent. The only thing we ever receive is your email, and only only when you ask for your full PDF report.
Each question maps to a pillar of healthy aging that research links to how we age. Together they let the tool estimate your cellular age and show which areas help or hold you back.
About 2–4 minutes for the full 27 questions, or under a minute for the quick 8-question version.
Pick the closest option — this is an estimate, not an exam. You can retake it anytime as things change.
No. Everything stays on your device. Nothing is stored or sent unless you later ask for your full PDF report.
It is an educational estimate of how your habits relate to aging, shown as an age compared with your real age. Younger suggests your lifestyle is, on balance, working in your favour; older points to room to shift things. It is not a diagnosis.
No tool can promise a number will change. But the habits measured here are consistently associated with healthier aging — use the simulator to see which changes would move your estimate most, and discuss any plans with your doctor.
They are two independent methods. The lifestyle score comes from habits and is capped for realism; PhenoAge comes from bloodwork and reflects biology, so it can sit further from your real age. Lab Mode replaces — it does not add to — your lifestyle score.
There is no single good number — what matters is the trend and how your habits compare. Many people land within a few years of their real age. Use the result to spot your biggest levers, not to chase a target.
PhenoAge (Levine 2018) combines nine routine markers — albumin, creatinine, glucose, CRP, lymphocyte %, MCV, RDW, alkaline phosphatase and white-cell count — with your age, through a published statistical model, into a single age-equivalent shown to track long-term health better than chronological age.
Habits take weeks to shift, so retaking every 4–6 weeks is a sensible rhythm. Your last result is saved on your device so you can see what has changed.
Use your top levers as a short, realistic to-do list, talk to a healthcare professional before making changes, and retake in about a month to see how habits move your estimate.
No. It is educational only — not a diagnosis, treatment, or measurement of your cells. Always consult a qualified professional for health decisions.
Both versions of the report include: your cellular age result and gauge; a seven-pillar radar with your scores; a practical how-to chapter for each of the seven pillars; your three biggest levers; a 30-day starter plan; a day-of-wellness rhythm; a myths-vs-facts section; a curated evidence library; a glossary; a transparent methodology; and an optional, validated PhenoAge from your bloodwork (Lab Mode).
The 8-question quick check (about 15 pages) gives you the full structure: your result, all seven pillar scores, a how-to for each pillar, your levers, a 30-day plan, and the evidence library. The 27-question complete check (about 18 pages) reads each pillar more finely and adds deeper, more practical detail.

No. The report is built entirely from your answers. If you happen to have recent bloodwork, you can optionally add Lab Mode for a validated PhenoAge (nine routine markers plus your age, Levine 2018) — but it is entirely optional.
Yes — it is free and instant, with no payment required. You enter your email to open your full PDF report, and to receive occasional evidence-based notes that you can unsubscribe from anytime.
Your lifestyle estimate starts from your real age and adjusts up or down across seven evidence-informed pillars of healthy aging. If you add bloodwork, Lab Mode also computes a validated PhenoAge using the published Levine 2018 method. Both are educational estimates, not a diagnosis.
Yes. Your answers and any blood values are processed on your device to generate the report; they are not stored or sent to a server. Only your email is captured, so we can send your report and occasional notes.
