Fatigue, bloating, brain fog, flushing, anxiety -- if you've spent years dealing with symptoms like these without answers, you're not alone.
Histamine Tracker surfaces patterns in your logged data -- connecting what you ate hours earlier to how you feel later -- so you can explore observations you might otherwise miss.
SCAN FOOD WITH YOUR CAMERA
Point your phone at any meal, menu, or ingredient label and instantly see its histamine level. No searching, no typing -- just snap and know what you're dealing with.
TRACK YOUR WAY
Log meals, symptoms, supplements, and activities naturally. Just type what you ate or how you feel -- no tedious dropdowns or calorie counting.
DAILY FINDINGS THAT SURFACE PATTERNS
After you log entries, the app automatically generates a personalized daily finding. It surfaces patterns in your own data -- connecting meals logged hours earlier to symptoms you noticed later -- and suggests observations worth exploring.
1,000+ FOODS RATED BY HISTAMINE LEVEL
Browse a comprehensive food database organized by category. Every food is rated Low, Moderate, or High histamine so you can make more informed choices.
EXPAND YOUR DIET WITH CONFIDENCE
Many people with histamine intolerance eliminate too many foods unnecessarily. Your logged data helps surface which foods may be worth exploring further, so you can expand your diet with more confidence.
SET GOALS, GET PERSONALIZED INSIGHTS
Tell the app which foods you want to avoid, your ideal sleep schedule, and your wellness goals. Every finding is based on your own entries and personal goals.
SHARE WITH YOUR HEALTH PRACTITIONER
Export your full journal and daily reports in a clean format you can paste into an email or bring to an appointment.

BUILT BY SOMEONE WHO LIVES WITH HISTAMINE INTOLERANCE
After years of struggling with histamine intolerance, insomnia, and chronic pain, I worked with nutritionists, therapists, and sleep specialists to understand how food, sleep, stress, and daily habits affect my symptoms. What I kept wishing for was a simple way to track everything together. So I built it. I use Histamine Tracker every day, and I hope it helps you too.
