Lab Book

Lab Book — your own private health logbook

Lab Book is a private place to keep the health numbers you already own — blood-panel values, blood pressure, scan results, body measurements, doctor's-visit notes — typed in yourself or imported from a CSV, and to line a marker up against your wearable signals. Everything stays on your device.

It is the inverse of a "labs" subscription. WHOOP/Function/Superpower sell you blood tests and store the results in their cloud where the company reads them. NOOP's pitch is the opposite: you bring numbers you already own, and they never leave the device.

Lab Book is a private notebook, not a medical service. NOOP stores and lines up the numbers you enter yourself. It does not test you, read your results, give medical advice, or diagnose anything. Please read the "How to read it honestly" section below — the framing here matters.

What you need

• Numbers from your own appointments, pharmacy, or home BP cuff. Nothing else — no account, no test to buy.

How to open it

Open Health → Lab Book. On first use, read the one-time "A private notebook, not a medical service" note and tap "Got it."

---

Add a marker reading

1. Tap "Add a reading."
2. Search the marker list (e.g. "LDL", "ferritin", "glucose") and pick one — or tap "Add a custom marker" and type your own name and unit, so you're never limited to NOOP's list.
3. Enter the value (the canonical unit is prefilled; where it makes sense, e.g. mmol/L ↔ mg/dL, there's a unit switcher that shows the conversion).
4. Set the date and time taken.
5. Optionally add a note, and a "reference range from my report" — whatever your own report printed. (NOOP shows this verbatim with a "from your report" tag; it never computes a range of its own.)
6. Blood pressure is entered as a systolic + diastolic pair so it reads naturally.
7. Save the reading.

To bring in a batch, use the Markers CSV card in Data Sources (date, marker name, value, unit, note).

See a marker's trend

Tap a marker to open its detail: the full reading history (table + line chart), a plain trend sentence ("3 readings, trending down"), and any reference text you entered shown verbatim.

Compare a marker with a wearable signal

This is the part only a local app that owns your wearable data can do:

1. On a marker, tap "Compare with a signal."
2. Choose a wearable metric — resting HR, HRV, sleep, Charge, weight, and so on.
3. Choose a trailing window — 7, 14 or 30 days. (Bloods are taken every few months, so NOOP pairs each reading with the average of your wearable signal over the window before the draw — "what your body was doing in the fortnight before." The window is shown and adjustable.)
4. Read the result: an r value, the exact number of readings used, and a restrained sentence — "when LDL is higher, HRV tends to be lower." Below a minimum number of readings, NOOP shows the dots but withholds a conclusion ("not enough readings to read a trend yet").

How to read it honestly

This is the load-bearing part, and it's non-negotiable:

• NOOP stores and lines up the numbers you enter — it does not test you, read your results, give medical advice, or diagnose anything.
• Anything you see, including a side-by-side trend, is your own information shown back to you. It's an association, never a cause, and never a medical finding.
• NOOP never decides whether a value is "normal", "high" or "low". Any reference range shown is exactly what you typed from your own report. NOOP ships no reference-range tables of its own.
• Always rely on your doctor, pharmacist or a qualified professional to interpret results and make decisions. If a number worries you, talk to them — not to an app.

Privacy

Your records never leave your device. There is no account, no cloud, no NOOP server. Because NOOP is an independent app you run yourself — not a healthcare provider — it is not "HIPAA-covered", and that protection does not apply here; the safety comes from the data being local-only and yours.

If you ever let the Coach use this data, it's a separate, explicit opt-in ("Also share my patterns & Lab Book"), off by default — and even then only a compact summary is sent to the provider you chose, never your full history.
