Food and symptom tracker
A food and symptom tracker that does the matching for you.
A food diary only helps if you can read it. agni logs meals in seconds, asks how you feel afterwards, and tells you which foods keep showing up before your bad days.
01 · Fast logging
Log a meal however is quickest.
- Photo: agni breaks the meal into ingredients and portions
- Several photos of one meal, for a table full of dishes
- Barcode or a Nutrition Facts label for packaged food
- Menu photo when you eat out
- Voice or text: just say what you ate
Favorites and recent meals are one tap away for the things you eat every week.
02 · How you feel
Symptoms in a tap, and a check-in after each meal.
Pick symptoms from a list made for your gut, rate each from minimal to extreme, and add your stress level. Log stool on the Bristol scale too.
About two and a half hours after a meal, agni can ask how it went: good, discomfort, or bad. One tap, and the meal is linked to how you felt.
03 · The part a paper diary can't do
agni finds the pattern, and says how sure it is.
For every food and ingredient, agni compares how often symptoms follow it with how you usually feel after eating. It checks each kind of symptom over its own time window, ignores foods that only look guilty because they travel together, and runs a significance test before it flags anything.
Each trigger is marked learning, confident, or confirmed, and older data counts for less, so your list keeps up with you. It also finds your safe foods.
04 · Share it
Turn your log into a report your doctor can read.
Export a PDF for any range: symptom frequency and timeline, stool pattern, flagged foods, eating patterns, and medications, with a summary on page one. Share it from your phone or with a QR code.

gut symptom scores. In a controlled trial, people with IBS scored about 50% lower on a low-FODMAP diet, the kind of FODMAP triggers agni helps you pinpoint.

Questions, answered.
What is the best food and symptom tracker app?
Look for one that does the matching for you, not just a diary and charts. agni does: it checks each kind of symptom over its own time window, says how sure it is about each trigger, and turns your log into a PDF report for your doctor.
What should a food and symptom tracker include?
Everything you eat and drink with times and rough portions, each symptom with a time and severity, bowel movements, and things that change symptoms on their own, like stress, sleep, and medication.
Is there an app that finds food intolerances?
agni finds foods that are linked to your symptoms in your own logs, which is how dietitians usually look for food sensitivities. It is not a medical test and cannot diagnose an allergy or intolerance.
Can I log food without photos?
Yes. You can type or say what you ate, scan a barcode or Nutrition Facts label, or pick from your favorites and recent meals.
Does agni connect to Apple Health?
agni reads sleep, steps, workouts, and cycle data from Apple Health so they show up next to your symptoms. It does not write anything to Apple Health.
