Private pilot · Opening soon

Measure the thing that decides everything else.

Hormones are upstream of energy, sleep, mood, strength, focus, recovery and how well you age. They are also the one thing almost nobody measures. Baseline makes that measurable — and builds the evidence out of the people actually living it, rather than whoever is selling something.

The problem

Everyone is optimising downstream.

People count steps and calories for years without ever looking at the signal that decides what the body does with either.

01

Nearly everything you track is a symptom

Energy, sleep, mood, recovery, fertility — these are not separate systems. They are your endocrine system expressing itself.

02

The evidence is thin, and sold to you

Most of what circulates about hormone health comes from someone with a product attached. Almost none of it carries numbers you can check.

03

"That's just your age"

Which is why so many people are doing everything correctly and still feel terrible — and get told there is nothing to look at.

Mission

Get hormones right and everything else gets easier. Get them wrong and nothing else fully works.

I believe optimising hormones is the highest-leverage thing a person can do for their health, because there is nothing downstream it does not touch.

Baseline exists to make that measurable, and to build the evidence out of the people actually living it. Not authority, not whoever is selling something — thousands of ordinary lives, recorded properly, over time.

That only means anything if it can go against me. If the data says something I believe does nothing, it goes in anyway. A record you cannot be wrong in front of is not worth keeping.

The urgency is generational. Our environment changed faster than our biology did, and whoever inherits it inherits what we did and did not bother to find out. That work starts now or it does not happen.

What it is

A community and research platform for hormone health.

You log your own data. You review the products and practices you actually use. Over time, you join screened protocols. The dataset that emerges is the product — the social layer is how it gets collected.

1

Log

A daily check-in that takes under a minute, plus your lab panels whenever you get them.

2

See

Your own trends against reference ranges. Two points are not a trend — twelve are.

3

Link

A review says "my testosterone went up" and points at the measurements that prove it.

4

Prove

Evidence scores recompute from primary data — yours and the published literature, weighed separately.

Features

What's built, and what comes next.

Baseline is being built in phases, deliberately. Everything in the first list is written and running in the pilot today.

In the pilot

Live

The daily log

One short check-in, with a streak. The whole product rests on whether this loop is worth returning to, so it is the only thing built so far.

Manual lab entry

Eleven hormone and metabolic markers, entered in whatever unit your lab printed. Date, time of day and fasting state come with it, because a cortisol reading without a time is not a reading.

Automatic unit conversion

Testosterone is ng/dL in the US and nmol/L nearly everywhere else — a factor of about 29. Values convert once, on the way in, and exactly what you typed is kept alongside forever.

Plausibility check

A value far outside the reference range stops and asks "does this look right?" before it saves. That one dialog catches most unit mistakes at the point of entry, where they are still cheap.

Trends with reference ranges

Every marker charted against the range it should sit in, so a number means something the moment you look at it.

Reminders

One nudge, at an hour you choose, that you can turn off in a tap. Not a notification stream.

Lab photo as a transcription aid

Photograph your panel so you can read it while typing. The image stays on your device and is deleted the moment you save or cancel. There is no upload path, by design.

Export everything, from day one

A complete CSV of your own data, on demand. Not a feature request — a starting condition.

A privacy ledger that starts empty

A record of who accessed your data and why, running from the first day rather than added once there is something to explain.

A public evidence library

Graded, cited answers to common hormone questions — with the actual numbers, and the study that disagrees. Open to anyone, no account needed.

What comes next

Planned

What you can track

Eleven markers, today.

Each one carries its reference range, its accepted units, and a note on how to make the reading actually comparable — morning draws, fasting state, cycle day.

Principles

The rules that don't bend.

These are enforced in the database, not promised in a policy page. Most of them cost something — that is roughly the point.

  1. Your record is append-only

    A measured value is never edited. Correcting one writes a new row and marks the old one superseded. A dataset where history can be quietly rewritten is not a research dataset, and researchers are right not to trust one.

  2. Units convert once, and the original is kept forever

    Mixed units produce aggregates that look completely plausible and are completely wrong, and you do not notice for months. Keeping what you actually typed means a bad conversion is recoverable instead of permanent.

  3. Consent is a database policy, not a promise

    Who can see a row is decided by the database on every single query. Not by an application remembering to filter, and not by a company remembering its own privacy page.

  4. Popularity and evidence never mix

    Star ratings and evidence scores are computed separately and are never merged. A thing can be beloved and useless at the same time, and the interface has to be able to say so.

  5. Reporting that something didn't work pays more than reporting that it did

    Publication bias is the failure mode most likely to quietly ruin a dataset like this. So the incentive is inverted at the source: a null result earns more standing than a positive one.

  6. How confident a number is depends on where it came from

    Typed by hand, read from a PDF, or delivered straight from the lab — each carries a different confidence, set by the path it arrived through. No setting anywhere lets a user raise it.

  7. "Your results are real and your explanation is wrong"

    Being able to say that without flinching is the entire differentiator. Someone can feel dramatically better and be completely wrong about why, and a platform that cannot separate those two things is just another marketing channel.

Privacy & scope

What Baseline will and won't do with your data.

This is health data about your body. The commitments below are structural — they were built in before there were any users to reassure.

Where it stands

Built in phases, on purpose.

Almost everything on the roadmap is more interesting to build than the logging loop. All of it waits anyway.

FoundationDone

Accounts, the consent model, the data model, the brand. The security policies were written before the features they protect.

The logging loopBuilt

Daily logs, lab entry, unit conversion, trends, reminders, export. Live now as a private web pilot.

ValidationHappening now

Fifty people, four weeks, and one number that decides what happens next.

Social & evidenceNext

Reviews linked to measurements, evidence scoring, the study library.

Structure & ingestionLater

Protocols and enrolment, aggregate insights, PDF import, wearables.

ResearchLater

The researcher console, consented exports, clinician verification.

The gate: 50 people, 4 weeks. At least 40% have to come back and log again in week two.

Above that, the next phase gets built. Below it, the loop itself is the problem and no amount of social features would rescue it. Nothing past the logging loop gets built until that number exists — because building on a guess is how you end up with a beautiful product nobody opens twice.

Get in touch

Ask anything, or ask to get in early.

The pilot is small and deliberately so. If you measure your own hormones, or you want to start, say so below and you'll be first in when it opens.

Finn · Baseline I'm building this on my own, so this box reaches me directly rather than a support desk. Ask about the science, the privacy model, what's actually built, or how to get into the pilot. I read everything and reply within a couple of days — leave an email if you'd like an answer back.

Your message is stored so I can answer it, and it is never published, shared or used as research data. An email address is optional — without one I simply have no way to reply. Please don't send anything you'd want kept confidential, and don't include lab reports or documents.
