Severity with structure.
Fourteen curated GI symptoms — bloating to brain fog — on a 0–10 clinical severity scale, with duration, body area, and triggers like "After eating" or "Poor sleep."
The Wellness Journal
The signal everyone has. The record no one keeps.
StatsKey turns gut health into structured, private, clinician-legible data: a fifteen-second Gut Check with Bristol-scale precision, a live 0–10 GI Burden Score, Face ID on the record, and a straight line from every episode back to what you ate.
Private by default — wellness records never appear to friends, red flags never become diagnoses, and the whole bowel record can sit behind a passcode and Face ID.

Around 40% of people live with a gut–brain disorder, and most hide it — even from their own doctor. StatsKey makes the hardest signal in health effortless to record, impossible to judge, and ready to answer for itself.
The Gut Check
Seven types. Mixed episodes. Fifteen seconds.
The recorder is three tabs deep and zero judgment wide. Most days it's two taps; on the days that matter, it captures what a gastroenterologist would actually ask about.
Type
The Bristol scale, color-coded and named — and when one movement changes form mid-episode, add phases: each gets its own type and portion, from Trace to All.
Timing
Quick-select capsules (1–20 min), an exact minutes:seconds entry, or a live stopwatch you start when you sit down.
Details
Size, color, urgency, control, passage, cleanup, red flags, a private photo, feel tags, and notes — every one optional, every one structured.
Bristol Stool Form Scale (Lewis & Heaton, 1997) — the same instrument used in IBS clinical trials.
Bristol scale tap a type
Mixed episode tap a phase to change its portion
Same movement, two phases — the burden model reads the worst phase, weighted by how much of the episode it was.
GI Burden Score
Every episode, scored 0–10. This is the exact model.
Not a vibe, not a smiley face — a deterministic score built from form, urgency, passage, cleanup, and control, with red flags that refuse to be averaged away. The demo below runs the same math the app runs.

The app's exact model: worst phase (form × portion), plus urgency, passage, cleanup, and control — any red flag floors the score at 8. It summarizes burden; it never diagnoses.
The full capture surface
Every dimension a clinician would ask about.
These aren't mockup words — this is the actual capture surface in the app, string for string. All of it optional, none of it awkward.

Red-flag entries never diagnose anything — they make a clinician summary clearer, and they always surface in the score.
Private by design
Your record. Your face to unlock it.
The Bowel Record Lock masks every bowel row in the app — timeline, history, search — behind a 4–8 digit passcode with Face ID or Touch ID. Unlock once; it relocks the moment the app leaves the foreground.
Private photos go further: owner-only cloud storage, never shown on the timeline, and blurred until you deliberately tap Reveal. Wellness records never appear to friends, and substance records are excluded from Intelligence, reports, and sharing by default.
Honest fine print, straight from the app: it is an in-app viewing lock, not end-to-end encryption — and a forgotten passcode requires re-confirming your sign-in to reset.

The gut–brain axis
Stress talks to your gut. Read the transcript.
The Gut-Brain Check-In takes fifteen seconds: mood, a 0–10 stress read, and optional gut symptoms. Record stress of 6 or higher alongside a symptom and StatsKey quietly tags stress as a trigger.
Once ten days carry both a stress reading and a gut record, the Patterns card computes a real correlation across your days — and tells you the honest version: a link, an inverse link, or "no clear pattern yet."
Pearson correlation on paired days only · requires ≥10 paired days and |r| ≥ 0.20 before claiming anything · high-stress vs calm-day contrast needs ≥4 days per bucket. An association, not proof — and not medical advice.

The whole journal
Five quick records. One timeline.
Bowel movements are the headline, but the journal reads your whole day: symptoms, mood, energy, and substances merge with meals into a single connected timeline — tap any entry to edit, and locked rows stay masked.
A date navigator walks you back through any day, and a 14-day GI Observation Block turns it into a focused experiment when you want one.
The live Wellness Journal — quick-record cards, the Gut-Brain Check-In, and the day's timeline. Actual screenshot.
Mood, with the mediator.
A five-point mood plus a 0–10 stress read underneath — because stress is the central mediator of the gut–brain axis, not a footnote to it.
Crashes, explained.
Five levels with crash time and context tags — post-meal crash, after caffeine, poor sleep, well rested — so the afternoon dip stops being a mystery.
The Gut Check.
The most complete gut recorder in consumer health — everything on this page, in a flow that usually takes two taps.
Recorded, not judged.
Nicotine, cannabis, alcohol, caffeine, and more across 14 intake methods, with one-tap templates and photo-scan intelligence — private by default, everywhere.
The day, assembled.
Wellness entries, meals, and substances on one connected-dot timeline with monospaced time stamps — the same view Intelligence reads when you ask about your day.
Ask your own gut
Intelligence that remembers what you ate before it hurt.
Intelligence carries tools built specifically for the gut: pull every meal from the hours before an episode, search any food across your history and check what followed within 24 hours, or read the full wellness timeline day by day — Bristol averages and burden scores ride along in context.
Grounded in your records · cites its methods · refuses to invent numbers · never diagnoses.
Rough gut afternoons this month — what did I eat beforehand?
get_full_wellness_timeline28 days · 41 recordsget_meals_before_event · 6h window9 meals matchedFour of your five high-burden afternoons (GI burden ≥ 6) followed a dairy-heavy lunch within six hours — average burden 6.2/10 versus 2.1/10 after other lunches. Both Type 6 episodes were tagged After Coffee. Worth one controlled retry before concluding anything.

A gut check that asks first.
An optional daily reminder — suggested for 9:00 AM — keeps the gut picture complete. Off by default, quiet-hours aware, and never smug about it.
The 4-hour check-back.
After a symptom or a loose episode, an optional follow-up asks "How's your gut now?" — answer "Still bothering me" or "Resolved" right from the notification.
Ninety minutes later.
An optional post-meal gut check lands 90 minutes after you eat — at most once a day — exactly when a food reaction is worth writing down.
Clinician-ready
Walk in with data, not a description.
One tap builds a GI Health Records section into your PDF report: totals, days recorded, daily average, ideal-Type-4 share, your full Bristol distribution with meanings, and per-day tables of time, form, color, size, urgency, and notes.
CSV ships a dedicated GI_RECORDS block; JSON carries every field — mixed episodes encoded like T4:most|T6:some — for anyone who wants the raw record.
Ten recorded meals plus four gut checks and your food–gut context is ready — the app counts it down for you and marks the milestone.

Wellness, not a medical device
The Wellness Journal is a self-tracking tool. GI burden summarizes what you recorded, red flags make a clinician summary clearer, and gut–brain patterns are associations — not proof, not diagnoses, and never a substitute for care.
Your gut already keeps score

The Wellness Journal is part of StatsKey — free to start, with the same fifteen-second capture philosophy as everything else: meals, glucose, training, and now the signal nobody talks about.
