Science & methodology

Conservative models, open about their edges.

Longevity is a field with real signal and real hype. We only use scoring methods that have been replicated in large cohort studies, and we tell you where each score is uncertain.

01 /

Based on replicated cohort data.

We combine established risk engines - QRISK3 for CV, FINDRISC for metabolic, and peer-reviewed equivalents for the other three domains - rather than a single black-box algorithm.

02 /

Every score carries a confidence interval.

When we don’t have enough input to be confident, we tell you - and we ask for the specific data point that would sharpen the number.

03 /

We never pretend a questionnaire is a lab.

When a biomarker would genuinely change your plan, we’ll say so - and connect you to a partner lab rather than guess.

04 /

Your data is separated from your identity.

Identifiers are encrypted at rest and never exposed to our AI layer. Health data is linked by UUID. Even our own engineers can’t read your records without your key.

How it works

Three steps, one morning.

No blood tests to book, no wearables to buy on day one. You answer honest questions, we do the maths, you get a plan you can actually follow. If you want deeper panels later, your clinician can add them.
STEP 01 · SEVEN MINUTES

Tell us about your life.

A plain-English intake: what you eat, how you sleep, how you move, who came before you. Save and come back - nothing is submitted until you confirm.

TYPICAL DURATION6m 42s
STEP 02 · CLINICAL MODELS

Your biological age, five domains scored.

We run your answers through five peer-reviewed risk models - cardiovascular, metabolic, neurological, oncological, musculoskeletal - and reconcile them into one age.

OUTPUT1 bio-age · 5 domain scores
STEP 03 · YOUR PROTOCOL

A plan written for one person.

Specific supplements, specific doses, specific timing - with the rationale for each. Download as a branded PDF, or take it to your GP.

What you get

Four things, no noise.

We’re deliberately small. No gamified streaks. No daily push notifications. No supplements we don’t believe in. Just the four things that matter on day one.
01 · BIO-AGE

The only number you actually need.

One figure. Updated every time your data changes. Compared honestly against your chronological age - no hype.

34.8yrs
02 · RISK SCORES

Five domains, measured.

Cardiovascular, metabolic, neurological, oncological, musculoskeletal - low, moderate, or high, with what’s driving each.

YOUR MODERATE DOMAINSMetabolic · Musculoskeletal
03 · SUPPLEMENTS

A protocol, not a pile.

3-7 supplements, specific doses, specific times - and the reason each one is on your list.
