Discover Hidden Links Between Your Food and Your Wellbeing.
Ever wonder if a food or ingredient might be affecting how you feel? Is dairy causing bloat? Does eating blueberries help increase your focus?
GutCheck is a privacy-first, offline-first mobile application designed to help you identify the specific triggers behind your digestive issues, migraines, brain fog, and energy fluctuations. Unlike traditional food diaries that focus on calorie counting and weight loss, GutCheck is a "health detective" tool built to uncover the complex correlations between the ingredients you consume and the wellness markers you track.
The Problem: Delayed Reactions & Hidden Triggers
Identifying food sensitivities is notoriously difficult. Symptoms like bloating, fatigue, or skin flare-ups often appear hours or even days after a meal. Most apps track "meals" (e.g., "Turkey Sandwich"), making it impossible to isolate the actual culprit—was it the gluten in the bread, the nitrates in the turkey, or the dairy in the cheese?
The Solution: Ingredient-Level Tracking & Local Analysis
GutCheck shifts the focus from meals to ingredients and from calories to symptoms. By tracking specific variables and correlating them with your self-defined wellness markers, the app provides a clear visual and statistical map of your health.
Key Features
- Ingredient-Focused Logging: Log the specific components of your food (e.g., gluten, dairy, nightshades, caffeine) rather than just meal names. The app uses frequency-based autocomplete to make logging fast and frictionless.
- Custom Wellness Markers: Track what matters to you. Create personalized markers like "Stomach Ache," "Mental Clarity," "Joint Pain," or "Energy Level" using a simple 1–10 scale.
- Multi-Marker Visualization: View your data on a multi-curve line chart. See exactly when you logged specific ingredients alongside your wellness trends. Ingredient icons are overlaid directly on the timeline, allowing you to spot patterns at a glance.
- Quick Insights (Correlation Engine): GutCheck uses Spearman rank correlation to analyze your data locally. After just 5 days of logging, the app can identify which ingredients are most strongly correlated with your wellness fluctuations, helping you pinpoint potential triggers or "superfoods."
- Privacy-First Architecture: Your data is yours alone. GutCheck operates entirely offline using a local SQLite database. There is no cloud sync, no data selling, and no requirement to create an account.
- Smart Reminders: Set one-time "Check-in" reminders (30 mins, 1, 2, 3, 4, 5 or 6 hours after eating) to prompt you to log how you feel, ensuring you capture delayed reactions while they are fresh in your mind.
- Secure & Portable: Protect sensitive actions (like data export or app reset) with biometric or PIN authentication. You can export your entire history as a JSON file at any time for your own records or to share with a healthcare professional.
Who is GutCheck for?
The Health Detective: Anyone struggling with IBS, migraines, fatigue or other symptoms that may be related to food who needs to identify food triggers through elimination or observation.
The Wellness Optimizer: Athletes and biohackers looking to verify if specific additions to their diet (like blueberries or turmeric) actually improve their recovery, mood, or mental clarity.
The Dietary Restricted: Individuals with Celiac disease, nut allergies, or severe intolerances who need a rigorous, ingredient-level log of their daily intake.
