Are you dealing with headaches, bloating, migraines, fatigue, IBS, skin reactions, or other symptoms — and wondering whether food may be involved? Track Change Thrive helps you see potential connections between what you eat and how you feel — without guesswork, spreadsheets, or juggling multiple apps. Start your free trial. Cancel anytime. No ads. No data selling. TCT was created by a systems engineer for his own family when symptoms continued without clear answers. The goal was simple: build a tool that reveals patterns and potential food-related triggers over time. What Track Change Thrive Does: - Log meals and symptoms in seconds. One entry powers analysis across foods, ingredients, allergens, and nutrients — giving you a clear, unified view. - Identifies four types of potential correlations between what you log and the symptoms you experience: • Foods you ate • Ingredients within those foods • Allergens present in the foods you logged • Nutrients associated with symptoms in established research **This multi-layer approach helps reveal potential patterns that traditional food or symptom trackers may not show. - Reveals science-informed nutrient insights • When you log a symptom, TCT highlights nutrients with known associations to that symptom — covering both potential deficiencies and excesses — giving you additional context to review. - Alerts you to allergens & ingredients you want to avoid • Flag allergens and ingredients you want to avoid. TCT automatically surfaces them during logging so you don’t have to inspect labels manually. Your dashboard also shows how consistently you're avoiding them. - Supports overall health with nutrition tracking • Track macros, secondary macros, vitamins, minerals, caffeine, and water while TCT focuses on identifying symptom-related patterns. - Reveals patterns and trends that naturally develop • Track symptoms over time and view how frequently foods, ingredients, allergens, or nutrients appear before the symptoms you log. Patterns strengthen as your entries grow. - Provides fast, reliable food logging • Search natural and branded foods, scan barcodes, build recipes, save favorites, and log meals quickly using a vetted database with over 1.4M foods. Logging stays fast, not frustrating. Why Track Change Thrive Is Different: - Most apps focus on general nutrition tracking, macros, or general health logging. Track Change Thrive is designed specifically for identifying potential symptom triggers. - TCT brings together: • Multi-layer correlations (foods, ingredients, allergens, nutrients) • Symptom tracking aligned to timing and severity • Fast and accurate food logging • Science-informed nutrient associations • The ability to replace multiple tools — symptom trackers/correlators, allergen/ingredient flaggers, macro/micronutrient apps, and basic food logs — with one system designed for clarity - Built around real struggles — not generic health goals — TCT focuses on helping you understand why symptoms may be occurring, not just recording them. Subscription & Trial - Start with a free trial and explore the app at your own pace. No ads. No selling of your data. Cancel anytime. Disclaimer: Track Change Thrive does not provide medical advice.
