The Longevity Lab

Wearable data + labs. One health picture.

Bring the pieces of your health together.

Longevity-focused analysis, without the clinic. Start with the data you already have — wearable numbers, lab results, or both. The Longevity Lab brings them into one clear view, shows what matters most, and helps you build your Longevity Protocol.

Already have bloodwork?

Your labs can show a part of the picture your wearable can't.

If your recent labs include the required markers, The Longevity Lab can calculate your biological age using PhenoAge, a published method based on standard blood markers. Your Master Synthesis also names the markers driving that result.

Wearables show the day-to-day pattern. Labs add metabolic, cardiovascular and biological-aging context. The Lab brings both together.

Who the Lab is built for.

  • Your recovery and sleep numbers have been drifting for months, and you're not sure why.
  • You're in perimenopause, and your sleep, temperature and HRV stopped behaving the way they used to.
  • You train hard, recover badly, and nobody has told you which of the two to fix.
  • You have four apps, plenty of numbers, and no clear place to start.
  • Nothing is wrong yet, and you would like to keep it that way.

Real output

This is what the Lab actually gives you.

What the Lab produces, and what using it looks like. The first is a real member’s output after adding bloodwork, including the biological age only labs can calculate. The second is the wearable-only path.

Master Synthesis · With labs

What it does: takes the findings that matter across your areas and puts them in one order — what to work on now, what can wait.

Resilience Score · Wearable only

What it does: reads what your wearable can measure, and says out loud how much of the picture it is working from.

Inside the Lab

The Resilience Score card on the wearable path, filled in: a score of 72 out of 100 built from 100% of measurable inputs; a box headed "Fitness Age: 30s" saying the member's cardiorespiratory fitness compares with what's typical for women in their 30s, with the line "This is a fitness measure, not your biological age" beneath it; and the five inputs counted toward the score with their points

Fitness Age is a lookup against an age- and sex-matched reference table — a fitness measure, not a biological age.

How the Lab works

A plan for each area. Then one order to work in.

  1. Step 1 — Build your baseline.

    Start with wearable data, labs, or both. Type in or paste the numbers you already have. If you use a wearable, bring those readings. If you have recent labs, bring those too. The Lab works from what is available and clearly shows what is still missing.

  2. Step 2 — Build your focused protocols.

    Work through the health areas that matter for your goals and your data — sleep, training, recovery, nutrition, body composition, hormonal transitions. Each one is a station inside the Lab, and each returns a practical plan of its own.

    • Sleep & Circadian
    • Training Plan
    • Stress & Recovery
    • Nutrition
    • Supplement Review
    • Body Composition

  3. Step 3 — Create your Master Synthesis.

    The relevant findings come together into your Longevity Protocol, one sequenced priority plan: what to work on now, and what can wait.

You work through the areas relevant to your data and goals, not all of them. What you see depends on what you have entered and what applies to you.

No noise. No alerts. Focused plans for the areas you're working on, and one Master Synthesis for your first priority.

Entering your numbers takes minutes. Work through the health areas relevant to you at your own pace. Calibrated every two weeks. Checked in every three months.

“My wearable already tells me things.”

It does — and that's a good start. Your wearable is a strong view of your recent sleep, recovery and activity. The Lab adds what sits around it: your bloodwork, your life stage, and what you've changed lately.

Add labs and the picture gets fuller, and bigger. A wearable trend, a lab panel and a training change each point at something different. Bringing them together is the work the Lab does for you.

What your free Baseline Audit shows

Enter the numbers you already have and the audit reads them together rather than app by app. It is a read of where you are now, and a pointer to the area worth looking at first — not the full plan itself.

  • The single largest constraint in your system — named, not scored
  • Your Resilience Score, and which direction it is actually moving
  • Sleep disruption patterns tied to your recovery, not reported separately
  • Metabolic and cardiovascular signals read together instead of app by app
  • The health area worth looking at first, and why

Your free Baseline Audit starts with whatever data you already have — wearable readings, labs, or both. Wearable data can show sleep, recovery and fitness patterns. Labs can add metabolic, cardiovascular and biological-aging context. Biological age is calculated with membership, and only when the required lab markers are available.

What membership adds

The audit tells you where you stand. Membership is where the plans get built.

  • A focused protocol for each health area relevant to you — sleep, training, recovery, nutrition and more
  • Master Synthesis — the findings that matter, in your Longevity Protocol, one sequenced priority plan
  • Pulse check-ins every two weeks, so the picture keeps up with you
  • Re-run any protocol when your training, sleep, recovery or life changes

Dual-engine validation

Every number is calculated or disclosed. Never guessed.

Most AI health tools skip straight to a recommendation. The Lab calculates first — then synthesizes. Every finding is traceable to its source.

Engine 1 — Deterministic clinical layer.

Recovery metrics, lipid ratios, and VO₂max estimates are calculated using published medical formulas, not inferred by an AI. Biological age is the one value that genuinely requires bloodwork — and if labs aren't on file, the system says so plainly rather than guessing.

Engine 2 — Synthesis layer.

The AI only works with verified outputs from Engine 1 plus your wearable and lab inputs. It does not recalculate clinical values. It does not override them. It does not invent missing data. It only synthesizes what is real.

You can trace any number in your protocol back to its source. Always.

The living system

Most longevity products hand you a report. This one answers back.

A plan built in January shouldn't still be guessing in March. So the Lab keeps reading.

Every two weeks, the Pulse. Log three numbers from your wearable — your 14-day average HRV, deep sleep, and resting heart rate. Sixty seconds. The system compares them against your protocol baseline and returns one directive: what's moving the right way, what isn't, and the single thing to focus on next. No bloodwork. No appointment. Just your wrist and a straight answer.

Any time life changes, re-run that area. New training block. Cut sugar. A brutal quarter. Update your training, nutrition, sleep or recovery plan the moment it happens, and that area is re-read against where you are now — not where you were at signup. When enough has moved, run your Master Synthesis again and the priority order is rebuilt around it.

Your Baseline and check-ins stay locked once saved, so your progress line stays honest no matter how often you update.

That's the difference between a report and a system: a report is true on the day it's printed. This one stays true.

While you decide, the Lab isn't idle: log a bi-weekly Pulse check-in from your wearable, or re-run any station once real time has passed — about two weeks is enough to see a genuine signal instead of noise. Neither ever resets your check-in dates, so there's no risk in exploring in between.

How does my data get in?
You paste or type in what you have — wearable data (Oura, Whoop, Hume Band, Fitbit, Apple Watch, Garmin), lab results, or both. For labs you can also upload the PDF or a photo of your report and the system reads the numbers off it — no formatting, no exports to wrangle. It takes minutes, you do it at each audit rather than daily, and your baseline builds the same day.
Do I need recent lab work to use The Longevity Lab?
No. Wearable data alone, labs alone, or both — your protocols adapt to whatever you bring. More inputs sharpen the synthesis, but neither one is a requirement to start. If you already have recent labs, bring them. When the required markers are present, they can also unlock your biological age calculation.
What if my wearable isn't listed?
If it exports data — HRV, sleep stages, resting heart rate — it works. Oura, Whoop, Hume Band, Fitbit, Apple Watch, and Garmin are the most common, but the platform isn't limited to them.
Do I have to wait a year to get anything useful?
No. Your free Baseline Audit shows what your numbers reveal as soon as you enter them: where you stand, what your signals are saying together, what your fragmented apps couldn't connect. Your focused protocols and priority plan for your year are the roadmap forward from there. The wait isn't a year — it's however long it takes you to enter your data.
What is the bi-weekly Pulse?
A 60-second check-in between your full audits, every 14 days. You log three metrics from your wearable — your 14-day average HRV, deep sleep, and resting heart rate. The system compares them against your protocol baseline and returns a short directional report: which numbers are moving the right way, which aren't, and one specific thing to focus on next. It keeps the protocol alive between audits without requiring a full re-analysis.
Can I re-run a station or check my Pulse more than once?
Yes — log a Pulse every 14 days, and update any station whenever something real changes: a new training block, cutting sugar, a stressful quarter. For real signal instead of noise, give any station at least two weeks between runs before checking again. Either way, this never touches your check-in dates — those check-ins lock once saved, so your progress comparison stays honest no matter how often you update your inputs. Your Station History page shows exactly when each station last changed, and your next report names what changed instead of leaving you to guess why a number moved.
I'm in my 40s — is it too early to start?
It's the right time to start — not too early. The hormonal transition can show up across sleep, recovery, temperature, energy and other patterns. Bloodwork can add metabolic, cardiovascular and other lab-based context that wearables cannot provide. Starting now means your protocol adjusts as those signals emerge instead of catching up after they've compounded. The members who benefit most from their year-end look-back are the ones who started at 40, not 55.
Is this built for women, or for men?
Both — and not generically. After 40 the protocol reads where you are in the menopause transition. For men after 45 it asks about energy, libido, mood, and changes in hair and skin, because andropause is real. Same depth, different biology. What it never does is hand you a plan designed for a 25-year-old and call it personalized.
Is this medical advice?
No. The Longevity Lab is an analysis and protocol-organization tool — it doesn't diagnose, treat, or replace your physician. It makes you the most prepared, most informed person in the room at your next appointment — so the conversation with your doctor is more specific and more actionable.
Who sees my health data?
You. Your data is stored encrypted, is never sold or shared, and you can delete it permanently at any time from inside the app.
