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.

This is exactly what I needed to track my foods and symptoms. It’s easy to use and very easy to understand. Love it!
