GutLedger

GutLedger is the private gut health diary built for people with IBS - by someone who has it. Track everything that matters: meals, symptoms, mood, stool, sleep, and fluid intake. Stored locally on your device. No accounts. No cloud. No data harvesting.

FOOD & DRINK DIARY

• Log meals with descriptions, photos, and barcode scanning
• Break multi-ingredient meals into components for accurate trigger tracking
• Built-in database of 470+ foods auto-tags entries as low, moderate, or high FODMAP
• Compound name recognition: "oat milk" -> lactose-free, "almond flour" -> low FODMAP
• Drinks tracked separately so you can spot coffee, alcohol, and tea triggers

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

GUT FEELING CHECK-INS (new in v2.5)

• Quick overall self-rating - "how's your gut today?" - that captures patterns the detailed log misses
• Time-of-day nudge rows surface a check-in when you usually need one
• Pairs with the meal log to correlate "felt rough" days back to the food trigger

MOOD, SLEEP & FLUID

• Rate mood and stress alongside 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 on every calendar view so you can correlate symptoms with hormonal changes

SMART INSIGHTS (PRO)

• Automatic trigger food detection with correlation scoring and lift over baseline
• Safe-foods report - the meals that never cause symptoms
• Send trigger foods to ListLedger as "avoid" tags, or to Settle as recipe filters
• Symptom heatmap, weekly trends, FODMAP load, day-of-week patterns

GUIDED FODMAP ELIMINATION DIET (PRO) Follow the gold-standard 3-phase protocol recommended by dietitians. Structured elimination phase with progress tracking, guided reintroduction challenges across all 7 FODMAP groups, and a personalisation phase showing your individual tolerances.
