follow the plan · keep the record · free beta

A pocket laboratory for the work between appointments.

n1lab helps you follow a complex health plan — the phases, the doses, the food trials, the daily observations — and bring a clear record of what actually happened back to your practitioner. It does not coach. The evidence is yours; the interpretation stays with you and the people guiding you.

§ 01 · Instruments

What it records.

01
AM check-ins
Sleep, how you woke, night waking and weight, plus anything notable from overnight.
02
PM check-ins
End-of-day burden across symptom domains. The day closes when both check-ins are recorded.
03
Your symptoms
Pick what you track from groups such as gut, mood, energy, sleep, pain and skin. Each is scored 0–10.
04
24h food trials
Three intra-day observation windows — 0–2h, 2–6h, 6–24h — read against your fourteen days before the trial.
05
The plan
Scheduled doses, food targets, standing rules — the protocol your practitioner wrote, carried as a daily surface instead of a PDF in a drawer.
06
The report
A dated record of your plan, check-ins, signals and trials, to print or save as a PDF for your practitioner.
§ 02 · Method

The method is older than the app. The app is just a clean place to do it.

STEP 01

Record what you notice.

Two check-ins a day. Add a trial when you're reintroducing a food. Drop a note when something feels off.

STEP 02

Watch shapes emerge over weeks.

Your symptoms are charted day by day on one 0–10 scale, with each trial marked on the day it started.

STEP 03

Decide what it means.

The app keeps the record. What it means is yours to decide, with the people guiding you.

§ 03 · Feature

Trial close-out.

A 24-hour food trial ends on one screen: each watched symptom against your 14 days before the trial, and the three windows’ readings. You record the outcome.

Your interpretation
The app records what you observed. You decide what it means.

No notable change from baseline.
Reaction observed
Symptoms increased within the window.
Inconclusive
Mixed signal, or confounded by other variables.
Aborted
Stopped early. Insufficient data.
Notes
"0–2h window felt unremarkable; flare came on around 3 hours in. Slept poorly the night before — possible confounder."
Confounders recorded at start: poor sleep, heavy caffeine, recent alcohol.
CAPTION · FIG 03

An example trial, with made-up data. One trial is suggestive, not conclusive.

§ 04 · Constraints

The things this app deliberately does not do.

Streaks
Adherence is not the goal. Some weeks you'll record carefully; some weeks you won't. The chart is unmoved either way.
no streaks
Badges
There is nothing to unlock. Observation is not a game; the reward is the record you keep.
no badges
Coaching
No scripted encouragement, no "let's do this." Reminders stay off until you turn them on. The app is a place to notice things, not to be motivated.
no coaching
§ 05 · On n=1

Why n=1 observation, when there are studies and protocols?

Population data tells you what is likely true on average; it cannot tell you what is true for you. If you live with symptoms like gut reactions, cognitive shifts, energy collapses or autonomic noise, you may have tried the protocols already. What your own body does is information no study was looking for.

The aim is modest. Record carefully. Wait. Hold every reading lightly until a second reading agrees with it. The app's job is to keep that loop clean — to make sure the next observation sits next to the last one, scaled the same way, on the same baseline, so a pattern has the chance to be a pattern instead of a feeling. And when someone is guiding you — a practitioner who wrote the plan — that same clean record is what you bring back: not a feeling about the month, but the month itself. The interpretation, where one is warranted at all, stays with the person doing the observing and the people they choose to read it with.
