GutLedger

GutLedger is a private, offline gut health diary built by someone who lives with IBS. Track everything that matters — meals, symptoms, mood, stool, sleep, and fluid intake — all stored securely on your device. No accounts, no cloud, no data harvesting.
FOOD & DRINK DIARY
Log meals with descriptions, photos, and barcode scanning. Break down multi-ingredient meals for better trigger tracking. The built-in database of 470+ foods auto-tags entries as low, moderate, or high FODMAP. Drinks are tracked separately so you can spot triggers like coffee or alcohol.
SYMPTOM & STOOL TRACKING
Record symptoms with type, severity, and duration. Log stools using the Bristol Stool Scale with optional photo records (auto-blurred for privacy). Track urgency and spot patterns over time.
MOOD, SLEEP & FLUID
Rate mood and stress alongside your gut symptoms to uncover the gut-brain connection. Log sleep quality and fluid intake with daily targets.
MENSTRUAL CYCLE TRACKING
Log periods and see how your cycle phase affects your gut. Period overlay appears on all calendar views so you can correlate symptoms with hormonal changes.
SMART INSIGHTS
Automatic trigger food detection with correlation percentages. Food-mood and sleep-symptom analysis. Symptom heatmap, weekly trends, and FODMAP load breakdown. Smart food suggestions with trigger warnings and predictive symptom alerts.
GUIDED FODMAP ELIMINATION DIET
Follow the gold-standard 3-phase protocol recommended by dietitians. Structured elimination phase with progress tracking, guided reintroduction challenges across 7 FODMAP groups, and a personalisation phase showing your tolerances.
PRO FEATURES (one-time purchase)
Barcode scanning, advanced trigger detection, PDF doctor reports, CSV export, database backup & restore, predictive alerts, elimination diet guide, cycle overlay, and smart suggestions.
PRIVACY FIRST
All data stays on your device. No accounts, no analytics, no telemetry, no ads. Biometric lock protects your health diary. GutLedger doesn't even need an internet connection.
Built independently by someone who gets it.
