GutSync: Food Sensitivity Log
Allergy & Gut Diary Tracker
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Find the foods triggering your symptoms. FODMAP, histamine & IBS tracker with intelligent correlation.
Are you eating well but still feeling bloated, tired, or unwell? GutSync reveals the hidden connection between what you eat and how your gut responds — so you can finally identify your food triggers and take control of your health.
**LOG FOOD IN SECONDS**
Tap a category, pick your meal, and move on. No calorie counting, no databases to browse. GutSync's quick-log system with emoji categories and a one-tap home screen widget makes tracking effortless — even on your worst gut days.
**SMART CORRELATION ENGINE**
Food reactions don't always happen immediately. GutSync analyzes patterns across a 2–72 hour window, linking what you ate to how you felt — and telling you which foods are most likely responsible. "Dairy → Bloating: 78% correlation" is the kind of insight that changes everything.
**ELIMINATION DIET PROTOCOLS BUILT IN**
Start a structured elimination diet without the guesswork. GutSync includes ready-to-use protocols for FODMAP, AIP, Histamine-Free, Gluten-Free, Dairy-Free, and Top-8 Allergen diets. Track your elimination phase, schedule reintroductions, and confirm your triggers — one food at a time.
**TRACK EVERY SYMPTOM**
Bloating, gas, nausea, abdominal pain, diarrhea, constipation, fatigue, skin reactions, brain fog, joint pain — log what you feel, when it started, and how severe it was. The more you log, the smarter your correlations become.
**FULL PICTURE WITH HEALTHKIT & WEATHERKIT**
Poor sleep, high stress, hormonal changes, and even weather pressure can all affect your gut. GutSync connects the dots between your HealthKit data (sleep, HRV, menstrual cycle) and your symptoms — revealing confounding factors your diet alone can't explain.
**PROFESSIONAL REPORTS FOR YOUR DOCTOR**
Generate clean, detailed PDF reports summarizing your food logs, symptom history, and correlations — formatted for your gastroenterologist or dietitian. Stop trying to remember every detail at your appointment.
**WIDGET & LIVE ACTIVITY**
Log meals and symptoms directly from your home screen or lock screen. Live Activity shows your active symptom timer on your Dynamic Island or lock screen.
**STAY MOTIVATED**
Daily logging streaks, milestone badges, and your personal Gut Score keep you engaged. The more consistent you are, the more accurate your insights.
GutSync is designed for people living with IBS, food sensitivities, lactose intolerance, gluten intolerance, histamine intolerance, and FODMAP issues.
Free tier: 10 food logs and 10 symptom logs per month. A subscription unlocks unlimited logging, full correlation history, all elimination protocols, HealthKit integration, PDF reports, and advanced widgets.
