Introduction

What GutSense does

GutSense is an offline-first iOS app that helps you capture daily gut-related events in a structured way and translate them into trends you can actually use. It is designed for people managing IBS-like patterns, elimination diets (including Low-FODMAP workflows), symptom recurrence, and appointment preparation.

Instead of keeping fragmented notes, GutSense gives you one timeline where meals, symptoms, stool entries, stress, mood, medication, and free notes all live together with timestamps.

The app calculates daily trigger and impact scores so you can quickly estimate whether your day is stable or overloaded. You can include or exclude individual events from scoring when needed, which keeps interpretation flexible and transparent.

Insights mode then visualizes pain trends, stool distributions, FODMAP meal exposure, lifestyle context, and HealthKit background signals (sleep and step trends if permission is granted). Correlation cards summarize potential trigger patterns while explicitly avoiding diagnostic claims.

For consultations, GutSense can generate a shareable PDF report with charts and optional event appendix. The app includes reminders, app lock, language selection, appearance mode, optional iCloud sync, and explicit privacy controls.

Timeline-first daily logging

The Timeline tab is your operational daily logbook. It is optimized for fast, repeated entries with consistent structure.

Insights and report generation

The Insights tab converts timeline data into interpretable visuals and summaries over multiple windows (1, 7, 30, 180, 365 days).

Feature Guide

Complete support overview

1. Onboarding and baseline setup

  • Step-based onboarding explains how to use the timeline, insights, correlations, export, and settings.
  • You can set display name, app language, and privacy storage mode during setup.
  • Baseline profile records your starting pain/stress/stool tendency so insights can compare progress over time.
  • FODMAP education is integrated in onboarding to give context before users start meal tracking.
  • Onboarding can be restarted later from Settings.

2. Meal logging and FODMAP detail

  • Meals support ingredient tags, note field, portion scaling, and location context (home/work/out/other).
  • Per-ingredient FODMAP flags and amount metadata are supported for more granular tracking.
  • Meal tag suggestions are generated from your own historic usage for faster repeat logging.
  • This structure helps separate "what was eaten" from "how much" and "where," which improves interpretation quality.

3. Symptom, stool, and alarm-context logging

  • Symptom events can include pain score, symptom types (e.g., bloating, cramping, nausea), and location notes.
  • Stool events include Bristol type, urgency, pain during bowel movement, blood flag, and mucus flag.
  • Blood-related stool markers are treated as safety-critical context and surfaced clearly in summaries.
  • All events remain editable, and detail screens preserve each data point for later review.
  • GutSense is a tracking tool only: it does not diagnose or provide treatment instructions.

4. Stress, mood, medication, and notes

  • Stress entries support stress score and optional energy score to capture functional load.
  • Mood entries include mood score and trigger tags (work, sleep, food, social, hormones, etc.).
  • Medication entries capture name, dose, and taken/not-taken state.
  • Free notes capture contextual events that do not fit strict forms (travel, sleep disruption, schedule changes).
  • Together, these entries reduce confounding when reviewing flare patterns.

5. Daily scoring and event control

  • Daily trigger and impact scores summarize the day in a compact, comparable format.
  • Events can be excluded from or included in scoring to handle outliers and non-representative entries.
  • Daily score cards update as data changes, giving immediate feedback while logging.
  • Home timeline cards can prioritize either recent-any or fixed meal/symptom/stool presets.
  • This system is intended for pattern awareness, not medical diagnosis.

6. Insights charts and trend windows

  • Selectable windows (1/7/30/180/365 days) support both short-term checks and long-term pattern review.
  • Chart groups include pain, stool type distribution, meal FODMAP load, context signals, and HealthKit context.
  • You can switch chart render modes and use smooth charts where preferred.
  • Correlation cards summarize candidate trigger links and potential confounders.
  • Trend labels are designed for practical interpretation before appointments or dietary reviews.

7. HealthKit context import

  • Optional HealthKit authorization imports background context such as sleep and cycle-related signals.
  • Import can be run from settings and typically processes recent periods (e.g., last 30 days or recent months).
  • HealthKit values are used as context overlays, not as clinical conclusions.
  • If permission is denied, GutSense keeps working with manual entries only.
  • This keeps the app usable both for privacy-focused users and users who want richer context.

8. Notifications and reminders

  • Daily logging reminders can be enabled with multiple reminder times per day.
  • Each reminder can be linked to a specific event type target (or left unassigned).
  • Reminder counts and times are configurable in settings.
  • Permission status is surfaced in-app, with quick link to iOS settings when denied.
  • Tapping a reminder routes directly into the timeline add flow for fast capture.

9. Privacy, storage, and app security

  • Offline-first architecture with on-device data storage by default.
  • Optional iCloud sync mode can be selected from Settings (restart may be required after switching).
  • No third-party analytics SDKs or external backend dependency in current architecture.
  • App lock via Face ID/Touch ID can protect data when reopening from background.
  • Users can clear all data or seed demo data from Settings for testing/training flows.

10. Export and sharing workflow

  • Insights can generate a PDF report with summary metrics and trend visualizations.
  • Report sections include pain trend, stool distribution timeline, meals/FODMAP, context and HealthKit charts.
  • Top trigger correlations and medication/supplement summaries are included.
  • Optional event appendix adds chronological event details to support consultation handoff.
  • Reports are shareable via iOS share sheet.

Tips & Workflow

How to use GutSense effectively

Time accuracy matters for pattern analysis. A quick entry now is usually more useful than a perfect entry hours later.
