What changed, and when.

A client's record in the practice area gains Energy. The requirement is estimated from inputs the practitioner enters. Energy in is read day by day from the client's food log, with how much of each day's log could be read.

Any logged food can be matched more closely with Refine: search the food composition data and set the grams eaten. The figures come from AUSNUT 2023, Food Standards Australia New Zealand's public food composition data.

Help opened on 4 October. Its first pages followed on 8 October: Start on your own, Do your morning check-in, Do your evening check-in, Where did Trials go? and Sign-in and email links. The check-in pages and Where did Trials go? carry pictures of the screens they describe.

Add n1lab to your Home Screen walks through installing n1lab on an iPhone, one picture per step. The beta invitation email carries the same steps. On an iPhone, reminders reach only the installed app.

Help is the last row of the More menu, at the foot of the sign-in and invitation screens, and in the practice sidebar. It offers Back to n1lab to the screen you came from.

A food trial watches the symptoms you choose: Symptoms to watch, up to five, at setup and in a running trial's menu.

What n1lab no longer needs is deleted on a schedule, such as old reminder records and devices that stopped taking reminders. Nothing is deleted because an account is quiet; accounts and files go only when their owner asks.

A care plan can hold a Medication beside a supplement, with the same dose grid.

Start a trial from the dose on your plan: Start a trial on this supplement or Start a trial on this medication. Choose Light, Standard or Detailed. Light is dose ticks and one question at the end. Standard compares up to three symptoms. Detailed adds a short daily entry.

At the end, the trial sets each symptom's average for the two weeks before the start against the average since, and says when a symptom was already moving before it began. You record the outcome yourself, and its confidence is always low.

Trends shades each supplement or medication trial as a band on the charts.

A practitioner you share your record with reads these trials, read-only and without your notes.

Reminders for a trial, off until you turn them on.

A plan update that touches a medication adds Check with your doctor before you change a medication. A practitioner drafting one is told that a change to a medication is for the client's prescriber.

The outcome screen shows what moved and the outcome it suggests, with its reasons, and asks for one confirmation: Record this outcome or Record a different one. A trial's menu can Abort this trial, Delete one with nothing recorded, or Reopen and Amend outcome on a closed one. Amendments stay listed on the record.

A food's page lists every run of that food in date order, and Trends' per-food section became Trials by food. A food introduction on your plan links to its trial, or offers Start a trial on this food.

Where the plan has dated stages, the overview compares the current stage with the one before. The record says when you last read it.

Choose up to five symptoms to focus on for each client. What moved leads with them, and the client list shows Last read. The focus is yours and is never written to the client's record.

Invitations work both ways. A practitioner can Invite a client and draft their first plan for the client to confirm, and can Accept or Decline a client's invitation from the client list.

Choose which symptom leads Today and Trends. It starts as your protocol's headline symptom.

Share your record, in Settings: Invite a practitioner by email, and see each read made on n1lab's screens in the Access log. You can withdraw an invitation or revoke access at any time.

A practitioner who accepts gets a practice area: a client list, and each client's overview, signals and full record. Every read on n1lab's screens is written to the client's access log.

Plan changes are proposed, never imposed. A practitioner drafts changes to a client's plan, and the client sees a line on Today such as "1 plan update to confirm". Nothing changes until the client confirms, and any change can be unticked first.

A practitioner can build their own groups of foods, supplements, medications or symptoms to read a record by. They are now called Group lenses, and clients never see them.

A Custom protocol sets Your rules: which food groups you remove, and how fast. Add your own names a symptom the catalogue lacks.

Reminders for the morning and evening check-ins, plan doses and food, each off until you turn it on. A reminder comes once a day, and only while the thing is still undone.

A one-time Beta participation screen sets out what usage information the beta may include, what it never includes, and what is off.

At the end of a plan stage you can continue it, a week at a time, as well as start the next one.

More symptoms to choose from, nausea, reflux, joint pain, dizziness and palpitations among them. Tracked symptoms adds or stops a symptom mid-study, and past entries are kept.

The report lists Signals that rose in the period, with the rule it used and the days behind it.

Save PDF on the report, for the phone's share sheet.

A past day's plan record can be corrected: Edit plan record.

Taken is one list for anything you take: a medicine, a supplement, or a substance such as coffee or alcohol. Each add saves at once, and a dose from your plan ticks the plan too. A few hours later, Today asks once whether you felt anything.

Movement has its own screen: pick a kind, how long, and Easy, Steady or Hard.

Exposures record a change that stays changed, such as a new product, a course of medication or a change in your surroundings. File one from the evening check-in's Something new in the mix? It shows on the day's record, as a shaded range on Trends, and in the report.

The plan's daily measures, water and urine colour, show on the Plan page with today's reading.

A printable Protocol report — observation record of your own record, over a range you choose: record quality, the plan record, self-scored signals, daily measures, trials, and only the notes you tick. It is in Settings, under Report.

Added to an iPhone Home Screen, n1lab opens full-screen with its own name and icon, clear of the notch. Pinch-zoom works across the app.

Terms and Privacy are linked from sign-in, sign-up and Settings, beside the line An observation journal, not medical advice.

A Skin group joined the symptom catalogue: itching, rash or irritation, dryness or flaking, flushing or redness, and breakouts. It was pre-ticked at setup for every protocol.

A Plan screen holds a practitioner's protocol beside the diet study: the day's doses to tick or mark skipped, food introductions with weekly targets, tests to record, standing rules, and the plan's documents. The practitioner's own words are always shown as a quote.

An Adherence record, week by week, with no percentages and no streaks.

Enter your practitioner's plan yourself, in four steps from the document, ending in a Read-back that shows the plan as the Plan screen will. A half-entered plan is kept as a draft.

With an active plan, Trends opens with the plan: doses scheduled against doses taken each day, water against the plan's target, and a weekly card for each introduction food.

A plan test such as a transit marker test keeps one run open from Eaten at to First seen. Each time can be amended, and a sighting can be marked Not certain it was the marker.

Six protocols: Lion Diet, Carnivore, AIP, Paleolithic, Low-FODMAP and Custom. Each curated protocol can begin with an on-ramp that removes its food groups week by week, or start from today if you are already eliminating.

Phases you move through yourself: on-ramp, elimination, strict and reintroduction.

A morning and an evening check-in, scored against the symptoms you chose to track, plus food and the day's events.

Food trials. A challenge tests one food against your baseline, and a staple observes a food you eat every day. Each trial has three observation windows: 0–2h, 2–6h and 6–24h. At the close, each symptom was drawn against a shaded band of your 14-day baseline, the context noted at the start was shown again, and a confidence line counted how many observations agreed.

Today, Trends and Notes, with every date in your own time zone.
